y=7x-5
2x+y=13
Answer:
x = 2, y = 9
Step-by-step explanation:
y = 7x - 5
2x + y = 13
These equations can both be set to equal y.
y = 7x - 5
y = -2x + 13
Now that they both equal y, you can set them equal to each other.
7x - 5 = -2x + 13
add 2x to both sides
9x - 5 = 13
add 5 to both sides
9x = 18
divide by 9
x = 2
plug x into either equation
y = 7(2) - 5
y = 14 - 5
y = 9
2(2) + y = 13
4 + y = 13
y = 9

What two numbers add up to -2 and multiple to 10
There are no two Real numbers that add up to -2 and multiply to 10.
The numbers that add up to -2 and multiply to 10, we can use algebraic methods. Let's denote the two numbers as x and y. Based on the given conditions, we can set up two equations:
Equation 1: x + y = -2
Equation 2: x * y = 10
To solve this system of equations, we can use substitution or elimination methods. Let's solve it using the substitution method:
1. Solve Equation 1 for x:
x = -2 - y
2. Substitute the value of x in Equation 2:
(-2 - y) * y = 10
3. Simplify the equation:
-2y - y^2 = 10
4. Rearrange the equation to standard form:
y^2 + 2y + 10 = 0
5. Since the equation is a quadratic equation, we can apply the quadratic formula:
y = (-b ± √(b^2 - 4ac)) / (2a)
In this case, a = 1, b = 2, and c = 10.
6. Calculate the discriminant: b^2 - 4ac:
2^2 - 4(1)(10) = 4 - 40 = -36
7. Since the discriminant is negative, the quadratic equation does not have real solutions. Therefore, there are no real numbers that satisfy both conditions of adding up to -2 and multiplying to 10.
In conclusion, there are no two real numbers that add up to -2 and multiply to 10.

What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
The given inequality is 4x > 1.2.
It can be solved as follows,
4x > 1.2
Divide both sides by 4 to obtain,
⇒ (4x ÷ 4) > (1.2 ÷ 4)
⇒ x > 0.3
Which implies that the values of x are greater than 0.3.
Analysing all the options give the result as 0.5.
Hence, the value of x that satisfies the given inequality is 0.5.

is not a solution.
An image of a coordinate plane shows a dashed horizontal line. The line crosses the y-axis at (0, 2) and passes through the points (2, 2) and (negative 2, 2). The area above the line is shaded.
Answer:
To determine if (0,3) is a solution to y>2, we need to check if y is greater than 2 when x=0 and y=3. Since 3 is greater than 2, the point (0,3) satisfies the inequality y>2.
To graph the inequality y>2, we need to shade the region above the horizontal line y=2. The line y=2 is a solid line since it includes the points where y=2, but the region above the line is shaded with a dashed line since it does not include the points where y=2.
Here is a description of the graph:
Draw a horizontal line passing through the point (0,2).
Shade the region above the line with a dashed line.
The graph visually represents all the points that satisfy the inequality y>2. Since the point (0,3) is above the line, it is part of the shaded region and satisfies the inequality.

Nathan deposits $940 every 2 months into his daughter's RESP. If the account earns 3.99% / annual, compound quarterly, how much will be in the account after 25 years?
There will be approximately $594,311.34 in Nathan's daughter's RESP after 25 years of depositing $940 every 2 months with a 3.99% annual interest rate compounded quarterly.
To calculate the amount in Nathan's daughter's RESP after 25 years, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = Final amount (amount in the account after 25 years)
P = Principal amount (amount deposited every 2 months)
r = Annual interest rate (in decimal form)
n = Number of times the interest is compounded per year
t = Number of years
In this case, Nathan deposits $940 every 2 months, so the principal amount (P) is $940. The annual interest rate (r) is 3.99% or 0.0399 in decimal form. Since the interest is compounded quarterly, the compounding frequency (n) is 4. The number of years (t) is 25.
Since Nathan deposits every 2 months, we need to calculate the total number of deposits made over 25 years. There are 12 months in a year, so in 25 years, there will be 25 * 12 = 300 months. However, since Nathan deposits every 2 months, the number of deposits (m) is 300 / 2 = 150.
Now, we can substitute these values into the formula:
A = 940(1 + 0.0399/4)^(4*25)
Calculating the exponent first:
(1 + 0.0399/4)^(4*25) ≈ 2.703236
Now, substituting the calculated exponent and the number of deposits into the formula:
A = 940 * 2.703236 * 150 ≈ $594,311.34
Therefore, there will be approximately $594,311.34 in Nathan's daughter's RESP after 25 years of depositing $940 every 2 months with a 3.99% annual interest rate compounded quarterly.
It's important to note that this calculation assumes Nathan makes the same $940 deposit every 2 months consistently over the 25-year period and does not make any withdrawals from the account during that time. Additionally, the actual amount may vary slightly due to rounding and any potential changes in interest rates over the years.

What is f_x (0,0) if
Hint: use Limit
\(f_x(0,0)\) is the partial derivative of \(f\) with respect to \(x\) evaluated at the origin. By definition of derivative, this is the limit
\(\displaystyle f_x(0,0) = \lim_{x\to0} \frac{f(x,0) - f(0,0)}{x-0} = \lim_{x\to0} \frac{f(x,0)}x\)
We have by definition of \(f\),
\(f(x,0) = \dfrac{x^5}{x^4+0^4} = \dfrac{x^5}{x^4}\)

Scores for a common standardized college aptitude test are normally distributed with a mean of 496 and a standard deviation of 110. Randomly selected men are given a Test Preparation Course before taking this test. Assume, for sake of argument, that the preparation course has no effect. If 1 of the men is randomly selected, find the probability that his score is at least 545.7. P(X > 545.7)
Answer:
0.3257
Step-by-step explanation:
Given an approximately normal distribution:
Z = (x - mean) / standard deviation
Mean = 496 ; Standard deviation = 110
For :
P(x > 545.7)
We obtain the standardized, Z score
Z = (545.7 - 496) / 110
Z = 49.7 / 110
Z = 0.4518
Hence, using the Z distribution table :
P(Z > 0.4518) = 1 - P(Z < 0.4518)
P(Z > 0.4518) = 1 - 0.67429
P(Z > 0.4518) = 0.32571

Sharon runs a screen-printing business. To print T-shirts each day, it costs her $200 in labor plus $5 per T-shirt for materials. Her income is $15 for each T-shirt she sells. How many T-shirts does Sharon need to sell each day in order for her costs to equal her income for that day?
(i mainly need the equation for this problem)
Answer:
Equation: 15n = 200 + 5n
Number of T-shirts: 20
Step-by-step explanation:
We need to find an expression for the costs for 1 day for making n number of T-shirts and an expression for the income for 1 day for selling n number of T-shirts. Then we set the expressions equal and solve for n, the number of T-shirts.
Expenses in 1 day:
The expenses are a fixed cost of $200 plus the cost per T-shirt.
$200 plus $5 per T-shirt
We need an expression for the cost per T-shirt in terms of n, the number of T-shirts.
If she makes 1 T-shirt, she spends $5 * 1.
If she makes 2 T-shirts, she spends $5 * 2.
If she makes n T-shirts, she spends $5 * n, or simply 5n.
Her total costs for a day are:
200 + 5n
Income in 1 day:
All the income comes from selling T-shirts.
She sells 1 T-shirt for $15 * 1.
She sells 2 T-shirts for $15 * 2.
She sells n T-shirts for $15 * n, or simply 15n
Her total income for 1 day is:
15n
Now we set the costs equal to the income and solve for n.
15n = 200 + 5n <--------- here is the equation you need
Subtract 5n from both sides.
10n = 200
Divide both sides by 10.
n = 20
Answer: She needs to sell 20 T-shirts.
If you flip 11 coins, the probability of not getting all 11 tails is
The required probability of not getting all tails is 2037 / 2048.
Given that,
If you flip 11 coins, the probability of not getting all 11 tails is to be determined.
What is probability?
Probability can be defined as the ratio of favorable outcomes to the total number of events.
What is simplification?The process in mathematics to operate and interpret the function to make function simple or more understandable called simplify and the process is called simplification.
Since each coin has 2 possible outcomes for a single toss i.e either head or tail.
Total number of sample spaces for the 11 coins to be tossed = 2^11 = 2048
The number of favorable outcomes for all tails = 11
Probability of not getting all 11 tails = 1 - probability of all are tails
= 1 - 11 / 2048
= 2037 / 2048
Thus, the required probability of not getting all tails is 2037 / 2048.
