\(\boxed{\boxed{\pink{\sf \leadsto The \ x - intercept \ is \ (2,0) \ \& \ the \ y \ intercept \ is \ (-8,0) }}}\)

A linear equation is given to us and we are required to find x and y Intercepts to it. So the given linear equation to us is ,

\(\bf \implies 4x - y = 8 \\\\\bf\implies \dfrac{1}{8} \bigg( 4x -y\bigg) =\frac{1}{8}\times 8 \\\\\bf\implies \dfrac{4x}{8}-\dfrac{y}{8} = \dfrac{8}{8} \\\\\bf\implies \dfrac{x}{2}-\dfrac{y}{8}=1 \\\\\bf\implies\boxed{\red{\bf \dfrac{x}{2}+\dfrac{y}{-8}=1 }}\)

Hence on comparing to standard form we get

Answer:

x = (2,0)

y = (0,-8)

Step-by-step explanation:

Remember than an intercept always has the other number as 0.

Let's put this in standard form of a linear equation, or y = mx + b

4x - y = 8

-y = -4x + 8

y = 4x - 8

"b" is the y intercept. The y intercept is -8, or (0,-8)

Now, to find the x intercept, all we have to do is substitute 0 for y.

0 = 4x -8

8 = 4x

2 = x

The x intercept is 2, or (2,0)

Sarah's charges per hour for working during the week will be $9.5.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Sarah is a nanny who bills clients at various prices depending on whether she is working during the week or on the weekend. She worked 45 hours in a single week for a salary of $902.50, of which 5 hours were on the weekend. She worked 50 hours the next week, 10 of which were on the weekend, and made 1045 dollars.

Let x be the charge per working hour and y be the number of charges per hour during the weekend. Then the equation will be

45x + 5y = 902.5           ...1

50x + 10y = 1045

25x + 5y = 522.5          ...2

Subtract equation 2 from equation 1, then we have

45x - 25x = 902.5 - 522.5

20x = 380

x = 19

And the value of y will be

25 (19) + 5y = 522.5

475 + 5y = 522.5

5y = 47.5

y = 9.5

Sarah's charges per hour for working during the week will be $9.5.

To eliminate the roots in 1.1 and 1.2, we can use trigonometric substitution. In 1.1, we can substitute x = 4 sin(theta) to eliminate the root of 4. In 1.2, we can substitute z = 7 sin(theta) to eliminate the root of 7.

1.1. V64+2 + 1 We can substitute x = 4 sin(theta) to eliminate the root of 4. This gives us:

V64+2 + 1 = V(16 sin^2(theta) + 2 + 1) = V16 sin^2(theta) + V3 = 4 sin(theta) V3 1.2. V4z2 – 49

We can substitute z = 7 sin(theta) to eliminate the root of 7. This gives us:

V4z2 – 49 = V4(7 sin^2(theta)) – 49 = V28 sin^2(theta) – 49 = 7 sin(theta) V4 – 7 = 7 sin(theta) (2 – 1) = 7 sin(theta)

Here is a more detailed explanation of the substitution:

In 1.1, we know that the root of 4 is 2. We can substitute x = 4 sin(theta) to eliminate this root. This is because sin(theta) can take on any value between -1 and 1, including 2.

When we substitute x = 4 sin(theta), the expression becomes V64+2 + 1 = V(16 sin^2(theta) + 2 + 1) = V16 sin^2(theta) + V3 = 4 sin(theta) V3

In 1.2, we know that the root of 7 is 7/4. We can substitute z = 7 sin(theta) to eliminate this root. This is because sin(theta) can take on any value between -1 and 1, including 7/4.

When we substitute z = 7 sin(theta), the expression becomes: V4z2 – 49 = V4(7 sin^2(theta)) – 49 = V28 sin^2(theta) – 49 = 7 sin(theta) V4 – 7 = 7 sin(theta)

The graph of g is Transformation up 7 units.

what is Transformation?

A graph transformation is a method for altering an existing graph or graphed equation to create a different version of the graph that follows. The modification of algebraic equations is a typical form of algebraic issue.

solution:

From the question, we have the following parameters that can be used in our computation:

g(x) = f(x) + k

Also, we have the value of k to be

k = 7

From the question, we can interpret g(x) = f(x) + k as f(x) is shifted up by k units

This means that

g(x) = f(x) + k

So, we have

g(x) = f(x) + 7

Hence, the transformation is (a) translated up 7 units

Assuming steady growth over 5 years, the annual rate of appreciation using the formula for compound interest is found to be 172.31%.

If we assume a steady rate of growth over the past 5 years, we can use the formula for compound interest to calculate the annual rate of appreciation:

A = P(1 + r/n)⁽ⁿᵗ⁾

where A is the final value, P is the initial value, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

In this case, P = $65,000, A = $177,000, n = 1 (since the interest is compounded annually), and t = 5. Plugging these values into the formula and solving for r, we get:

$177,000 = $65,000(1 + r/1)⁽⁽¹⁾⁽⁵⁾⁾

2.7231 = 1 + r

r = 1.7231 = 172.31%

The critical value of F for a .05 significance level, with within-groups degrees of freedom of 15 and between-groups degrees of freedom of 5, is approximately 2.901.

To find the critical value of F, you need to consult an F-distribution table, which you can find in a statistics textbook or online. Using the table, locate the row corresponding to the between-groups degrees of freedom (5) and the column corresponding to the within-groups degrees of freedom (15). The intersection of this row and column will give you the critical value of F for a .05 significance level.

Remember that the critical value of F is used to determine whether there is a significant difference between group means in an analysis of variance (ANOVA) test. If your calculated F-value is greater than the critical value, you would reject the null hypothesis and conclude that there is a significant difference between the group means.

So to calculate 5 with an exponent of 3, you can write 5, 3 times with a multiplication symbol between them like so: 5 · 5 · 5 When we multiply them together, we get the answer to 5 with an exponent of 3.

Answer:

-3

Step-by-step explanation:

First - change the equation to y=mx+b format

3y/3 = 4x/3 - 17/3

y = 4/3x - 17/3

Second - then (2,y) plug x = 2

Third - solve

y = 4/3(2) - 17/3

y = 8/3 - 17/3 = -9/3 = -3

Therefore, the original number is 10x + y = 10(10) + 7 = 107.

Given that the sum of the digits is seventeen, we have the equation:

x + y = 17 (equation 1)

The number with the digits reversed is thirty more than 5 times the tens' digit of the original number. The number with the digits reversed would be 10y + x.

According to the given information, we have the equation:

10y + x = 5x + 30 (equation 2)

To solve the system of equations, we can substitute equation 1 into equation 2:

10(17 - x) + x = 5x + 30

Expanding and simplifying:

170 - 10x + x = 5x + 30

170 - 30 = 5x + 10x - x

140 = 14x

x = 10

Substituting the value of x back into equation 1:

10 + y = 17

y = 7

Therefore, the original number is 10x + y = 10(10) + 7 = 107.

Answer:

x = √2y^2 + 64 or x = √2y^2 + 64

Step-by-step explanation:

Solve for x.

x^2/64 - y^2/32 = 1

Step 1: Add 1/32 y^2 to both sides.

1/64 x^2 + -1/32 y^2 + 1/32 y^2 = 1 + 1/32 y^2

Step 2: Divide both sides by 1/64.

1/64 x^2/ 1/64 = 1/32 y^2 + 1/ 1/64

x^2 = 2y^2 + 64

Step 3:

x = √2y^2 + 64 or x = √2y^2 + 64

Answer:

x = √2y^2 + 64

Step-by-step explanation:

= 1/64 x^2 + -1/32 y^2 + 1/32 y^2 = 1 + 1/32 y^2

= 1/64 x^2/ 1/64 = 1/32 y^2 + 1/ 1/64

= x^2 = 2y^2 + 64

= x = √2y^2 + 64

[3] Answer: ∠DCB = 128°

Step-by-step explanation:

     First, we know a straight angle is equal to 180 degrees.

3x° + 5° + x° + 11° = 180°

4x° + 16° = 180°

4x° = 164°

x° = 41°

     Next, we can apply this same knowledge of straight angles to ∠DCA. We will substitute the value of x above into the expression for angle ACB.

180° - (x + 11)° = ∠DCB

180° - (41 + 11)° = ∠DCB

180° - 52° = ∠DCB

128° = ∠DCB

[4] Answer: ∠DEC = 126°, ∠BEC = 54°

Step-by-step explanation:

     We will also apply the knowledge of straight angles being equal to 180 degrees here.

5x° + 36° + 3x° = 180°

8x° + 36° = 180°

8x° = 144°

x° = 18°

     Next, we will substitute this value of x back into the expressions for each angle.

5x° + 36°              3x°

5(18)° + 36°          3(18)°

126°                     54°

     Lastly, we know that vertical angles are congruent.

∠AEB = ∠DEC = 126°

∠AED = ∠BEC = 54°

The first three laws of probability are: Law of Non-Negativity: The probability of any event is a non-negative number. It is always greater than or equal to zero.

Law of Additivity: For mutually exclusive events, the probability of the union of those events is equal to the sum of their individual probabilities. If events A and B are mutually exclusive, then the probability of A or B occurring is equal to the sum of the probability of A and the probability of B.

Law of Complementarity: The probability of the complement of an event is equal to one minus the probability of the event. If event A is the occurrence of an event, then the probability of not A (or the complement of A) is equal to 1 minus the probability of A.

The derivative, f'(-3), represents the slope of the function's tangent line at x = -3, and in this case, it equals -6.

The derivative of a function measures its rate of change at a specific point. To find the derivative of f(x) = x² + 17, we can use the definition of derivative, which states that the derivative of a function f at a point x is equal to the limit as h approaches 0 of [f(x + h) - f(x)] / h.

In our case, we want to find f'(-3), which means we need to evaluate the derivative of f(x) at x = -3. Plugging these values into the definition, we have:

f'(-3) = lim(h->0) [(f(-3 + h) - f(-3)) / h]

Expanding the function f(x) = x² + 17, we have:

f'(-3) = lim(h->0) [((-3 + h)² + 17) - ((-3)² + 17)] / h

Simplifying further:

f'(-3) = lim(h->0) [(9 - 6h + h² + 17) - (9 + 17)] / h

= lim(h->0) [h² - 6h] / h

= lim(h->0) h(h - 6) / h

The curl of the vector field F is given by the determinant:

curl(F) =

| i j k |

| ∂/∂x ∂/∂y ∂/∂z |

| xy+z² x² xz-2|

Taking the partial derivatives and evaluating the determinant, we get:

curl(F) = (2x, -z, y)

So the curl of F is (2x, -z, y).

To find the curl at the point (0, -1, 0), we substitute x=0, y=-1, and z=0 into the curl:

curl(F(0,-1,0)) = (2(0), -0, (-1)) = (0, 0, -1)

Therefore, the curl at the point (0, -1, 0) is (0, 0, -1).

Since the curl of F is not zero, the vector field F is not irrotational.

Step-by-step explanation:

Let's simplify the expression step by step: Expand the squared term:

(x - 3y)² = (x - 3y)(x - 3y) = x² - 6xy + 9y²

Expand the second term:

3(x + y)(x − 4y) = 3(x² - 4xy + xy - 4y²) = 3(x² - 3xy - 4y²)

Expand the third term:

x(3x + 4y + 3) = 3x² + 4xy + 3x

Now, let's combine all the expanded terms:

(x - 3y)² + 3(x + y)(x − 4y) + x(3x + 4y + 3)

= x² - 6xy + 9y² + 3(x² - 3xy - 4y²) + 3x² + 4xy + 3x

Combining like terms:
