Hey there! :)
Answer:
(5, -2), or x = 5 and y = -2.
Step-by-step explanation:
We can solve the two equations algebraically by eliminating a variable:
2x + 5y = 0
3x - 4y = 23
Eliminate the x variable by finding the least common multiple and multiplying both equations:
3(2x + 5y = 0)
2(3x - 4y = 23)
Distribute and subtract the bottom equation from the top:
6x + 15y = 0
6x - 8y = 46
------------------
0x + 23y = -46
23y = -46
y = -2.
Plug in y into an equation to solve for x:
2x + 5(-2) = 0
2x - 10 = 0
2x = 10
x = 5. Therefore:
The solution to this equation is (5, -2), or x = 5 and y = -2.
Answer:
x = 5; y = -2
Step-by-step explanation:
2x + 5y = 0
3x - 4y = 23
Let's eliminate y. Multiply the first equation by 4. Multiply the second equation by 5. Then add them.
8x + 20y = 0
(+) 15x - 20y = 115
------------------------------
23x = 115
x = 5
Now we substitute 5 for x in the first equation and solve for y.
2(5) + 5y = 0
5y = -10
y = -2
Solution: x = 5; y = -2

in symbolizing truth-functional claims, the word "if" used alone introduces the consequent of a condition. "only if" represents the antecedent.
In symbolizing truth-functional claims, the word "if" is used to introduce the consequent of a condition, while the phrase "only if" represents the antecedent.
Symbolizing truth-functional claims involves representing statements or propositions using logical symbols. When using the word "if" in a truth-functional claim, it typically introduces the consequent of a conditional statement. A conditional statement is a type of proposition that states that if one thing (the antecedent) is true, then another thing (the consequent) is also true. For example, the statement "If it is raining, then the ground is wet" can be symbolized as "p → q," where p represents "it is raining" and q represents "the ground is wet."
On the other hand, the phrase "only if" is used to represent the antecedent in a truth-functional claim. In a conditional statement using "only if," it states that if the consequent is true, then the antecedent must also be true. For example, the statement "The ground is wet only if it is raining" can be symbolized as "q → p," where p represents "it is raining" and q represents "the ground is wet."
In summary, when symbolizing truth-functional claims, the word "if" introduces the consequent of a condition, while the phrase "only if" represents the antecedent. These terms help express the relationships between propositions in logical statements.

Choose the equation below that represents the line that passes through the point (-2,-1)
and has a slope of 5.
The line that passes through the point (-2,-1) and has a slope of 5. The equation of the line is y + 1 = 5(x + 2).
What is slope of a line?
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively. The ratio of the increase in elevation between two points to the run in elevation between those same two points is referred to as the slope.
Using the slope and 1 point format: (y- y₁) = m(x - x₁)
where m = slope = 5, and point is (x₁, y₁). In this case point (x₁, y₁) = (-2, -1)
x₁ = -2, y₁ = -1
Using: (y- y₁) = m(x - x₁)
y - -1 = 5(x - -2)
y + 1 = 5(x + 2).

What is the solution of x3 – x2 > 9(x – 1)
Consider the cubic equation,
x³ - x² = 9 (x - 1)
We can solve this by factoring:
x³ - x² - 9x + 9 = 0
x² (x - 1) - 9 (x - 1) = 0
(x² - 9) (x - 1) = 0
(x - 3) (x + 3) (x - 1) = 0
So the cubic has roots at x = 3, x = -3, and x = 1. Split the real line into the open intervals (-∞, -3), (-3, 1), (1, 3), and (3, ∞). Check if the inequality holds for some test point taken from each interval:
• in (-∞, -3), take x = -4. Then
(-4)³ - (-4)² = -80
9 (-4 - 1) = -45
but -80 > -45 is not true. So this interval is not in the solution set.
• in (-3, -1), take x = -2. Then
(-2)³ - (-2)² = -12
9 (-2 - 1) = -27
and -12 > -27 is true. So x in (-3, -1) satisfies the inequality.
• in (1, 3), take x = 2. Then
2³ - 2² = 4
9 (2 - 1) = 9
but 4 > 9 is not true.
• in (3, ∞), take x = 4. Then
4³ - 4² = 48
9 (4 - 1) = 27
and 48 > 27 is true.
So, the complete solution set is
(-3, -1) U (3, ∞)
(where U denotes union)
AABC has vertices (-6,2), B (5,-1), and C (4,4). Classify AABC by its sides. Then determine whether it is a right triangle. (Hint: Draw the picture).
AABC is a scalene triangle and not a right triangle.To classify AABC by its sides, we need to examine the lengths of its sides. Using the distance formula, we can calculate the lengths of the three sides:
Side AB:
\(\sqrt (-6 - 5)^2 + (2 - (-1))^2] = \sqrt 11^2 + 3^2] = \sqrt(121 + 9) = \sqrt130\)
Side BC:
\(\sqrt(5 - 4)^2 + (-1 - 4)^2] = \sqrt1^2 + (-5)^2] = \sqrt(1 + 25) = \sqrt26\)
Side AC:
\(\sqrt(-6 - 4)^2 + (2 - 4)^2] = \sqrt(-10)^2 + (-2)^2] = \sqrt(100 + 4) = \sqrt104 = 2\sqrt26\)
Now, comparing the lengths of the sides, we find that AB ≠ BC ≠ AC. Since none of the sides are equal, AABC is classified as a scalene triangle.
To determine whether AABC is a right triangle, we can examine its angles. We can calculate the slopes of the sides to determine the relationship between them:
Slope AB = (2 - (-1))/(-6 - 5) = 3/(-11)
Slope BC = (4 - (-1))/(4 - 5) = 5/(-1)
Slope AC = (4 - 2)/(4 - (-6)) = 2/10 = 1/5
Since the slopes of the sides are not negative reciprocals of each other, the angles of AABC are not 90 degrees. Therefore, AABC is not a right triangle.

C = c0 + c1YD T = t0 + t1Y YD = Y – T
G and I are both constant. Assume that t1 is between 0 and 1.
Solve for taxes in equilibrium.
Suppose that the government starts with a balanced budget and that there is a drop in c0.
What happens to Y? What happens to taxes?
Suppose that the government cuts spending in order to keep the budget balanced. What will be the effect on Y? Does the cut in spending required to balance the budget counteract or reinforce the effect of the drop in c0 on output? (Don’t do the algebra. Use your intuition and give the answer in words.)
To solve for taxes in equilibrium, we can start by substituting the given equations into the equation for YD:
YD = Y - T
Since C and T are constant, we can write:
YD = (c0 + c1YD) - (t0 + t1Y)
Now, we can rearrange the equation to isolate YD:
YD = c0 + c1YD - t0 - t1Y
Simplifying further:
YD - c1YD = c0 - t0 - t1Y
Factoring out YD:
YD(1 - c1) = c0 - t0 - t1Y
Dividing both sides by (1 - c1):
YD = (c0 - t0 - t1Y) / (1 - c1)
Now, let's analyze the effects of a drop in c0. If c0 decreases, it implies that consumption decreases. As a result, YD will decrease, leading to a decrease in Y. Taxes will also decrease because they are determined by YD.
If the government cuts spending to balance the budget, it will lead to a decrease in G. This decrease in spending will reduce Y and further decrease YD. However, the impact on Y will depend on the magnitude of the cut in spending.
If the cut in spending is significant, it can counteract the decrease in output caused by the drop in c0. On the other hand, if the cut in spending is small, it may reinforce the effect of the drop in c0 on output. The overall effect on Y will depend on the relative magnitudes of the changes in c0 and G.
A drop in c0 will decrease both Y and taxes in equilibrium. If the government cuts spending to balance the budget, the effect on Y will depend on the magnitude of the cut in spending relative to the decrease in c0.

The cut in spending required to balance the budget counteracts the effect of the drop in c₀ on output (Y).
In equilibrium, taxes can be solved using the given equations:
C = c₀ + c₁YD
T = t₀+ t₁Y
YD = Y – T
To find taxes in equilibrium, we need to substitute the value of YD into the equation for taxes:
T = t₀ + t₁YD
Now, let's analyze the impact of a drop in c₀ on output (Y) and taxes (T).
When c₀ decreases, it means that the intercept of the consumption function (C) decreases.
This results in a decrease in consumption at every level of income. As a result, the aggregate demand decreases, leading to a decrease in output (Y).
The decrease in output (Y) leads to a decrease in income and, consequently, a decrease in disposable income (YD).
Since taxes (T) depend on disposable income, a decrease in YD will lead to a decrease in taxes (T).
Next, let's consider the effect of a government spending cut to balance the budget.
When the government cuts spending to balance the budget, it reduces its expenditure (G) without changing its tax revenue (T).
This reduction in government spending decreases aggregate demand, which in turn reduces output (Y).
However, since the government is keeping the budget balanced, the decrease in government spending is offset by the decrease in taxes (T) that occurs as a result of the decrease in output (Y).
Therefore, the cut in spending required to balance the budget counteracts the effect of the drop in c₀ on output (Y).

3. prove that the least upper bound of a nonempty subset s of r, if it exists, is unique.
The least upper bound (LUB) of a nonempty subset s of the real numbers (r) is a number m such that:
1. m is an upper bound of s, i.e., m ≥ x for all x ∈ s;
2. m is the least upper bound, i.e., if u is any upper bound of s, then u ≥ m.
To prove that the LUB of a nonempty subset s of r is unique, we need to show that if m and n are both LUBs of s, then m = n.
Assume that m and n are both LUBs of s. Since m is a LUB, we have that:
1. m is an upper bound of s, i.e., m ≥ x for all x ∈ s;
2. m is the least upper bound, i.e., if u is any upper bound of s, then u ≥ m.
Similarly, since n is a LUB, we have that:
1. n is an upper bound of s, i.e., n ≥ x for all x ∈ s;
2. n is the least upper bound, i.e., if u is any upper bound of s, then u ≥ n.
Now, suppose for contradiction that m ≠ n. Without loss of generality, assume that m < n. Since m is an upper bound of s, we have that m < n is not an upper bound of s. Therefore, there exists some element x in s such that m < x ≤ n. But this contradicts the fact that n is an upper bound of s. Therefore, our assumption that m ≠ n must be false, and we conclude that m = n.
We have shown that if m and n are both LUBs of a nonempty subset s of r, then m = n. Therefore, the LUB of s, if it exists, is unique.

The slope is -0.1 starting at 3.9, the GPA will decrease by 0.1 for each text sent in class.
Here we have to find the slope.
The equation given is:
y = 3.9 - 0.1x
As we know that the equation of a line is:
y = mx + c
Therefore we get that the slope is m = -0.1
Starting at 3.9 the GPA will decrease by 0.1 for every text sent in class ( for y = mx + b, a is the slope which is the coefficient of x)
Because the slope is less than 0, it is decreasing.
Therefore the slope is -0.1 and there is a decrease in GPA of 0.1.
