What is the slope of y=-2
Answer:
zero
Step-by-step explanation:
What is slope?
Slope is a line that measure's how steep the line is.
How did i get zero as my answer
Since the line is y = 2, that means it is a horizontal line. Slope is defined as rise over run. Since it is horizontal, there is no rise, only a run, which is a constant, 2. Therefore, it is 0.
Hence, the solution to this problem is 0.

8. ABC Company has sales price per unit for its only product at br. 13. The variable cost per unit is br. 5. In the year 2003 the company's sales was br. 1,040,000 which was 5000 units above the break-even output. a) Determine the fixed cost b) Compute the variable expense at the point of break-even.
a) The fixed cost for ABC Company in the year 2003 was Br. 600,000.
b) The variable expense at the break-even point for 2003 was Br. 375,000.
What is the break-even point?The break-even point refers to the sales units or revenue at which the total sales revenue equals the total costs (variable and fixed).
At the break-even point, ABC Company does not generate any profit or incur a loss.
Sales price per unit = Br. 13
Variable cost per unit = Br. 5
Contribution margin per unit = Br. 8 (Br. 13 - Br. 5)
Contribution margin ratio = 0.6154 (Br. 8 ÷ Br. 13)
Sales revenue for 2003 = Br. 1,040,000
Sales units for 2003 = 80,000 units (Br. 1,040,000 ÷ Br. 13)
Break-even units for 2003 = 75,000 units (80,000 - 5,000)
Break-even sales revenue = Br. 975,000 (Br. 13 x 75,000)
Variable expense at the break-even point = Br. 375,000 (Br. 5 x 75,000)
Fixed expenses = Br. 600,000 (Br. 975,000 - Br. 375,000)

7. The Taylor Rule states that the central bank should set the short-term nominal interest rate (i)
based on the inflation gap [the difference between inflation (3.14) and desired inflation (3.14*)] and the
output gap (the percentage difference between real GDP (Y) and potential GDP (Y*) An
example of a Taylor Rule would be the formula
i - 3.14 = 1.5 +0.5(3.14-3.14*) +0.5 (Y-Y*/Y*)
The term on the left-hand side is the real interest rate. Consider the following table
Inflation rate (3.14), %
Target inflation rate (3.14*), %

Calculate the real interest rate. Has the real interest rate moved in the direction that would
move the inflation rate toward its target?
c. How does scenario C differ from the base scenario in terms of the inflation and output gaps?
Calculate the real interest rate. Has the real interest rate moved in the direction that would
move output toward the potential level?
d. Suppose a new chair of the central bank is appointed and she switches to a new policy rule of
the form given in the next equation. Recalculate the real and nominal interest rates for the
three scenarios. What has been the effect of the change in weights?
i-3.14=1.5 +0.75(3.14-3.14*) +0.25(Y-Y*/Y*)
The weight on the inflation gap has increased from 0.5 to 0.75. The real interest rate is 16.86% and Nominal interest rate is 20%
a. In the base scenario, the real interest rate will be 20%, and the nominal interest rate will be 20%.
b. In scenario B, inflation rate will be higher (4%) compared to the base scenario (3.14%).
Output gap is 0% in both the scenarios, however, in the base scenario inflation gap is 0% (3.14 - 3.14) and in scenario B, inflation gap is 0.86% (4 - 3.14).
Now, let's calculate the real interest rate.
Real interest rate in base scenario = 20% - 3.14%
= 16.86%.
Real interest rate in scenario B = 20% - 3.14% + 1.5 + 0.5 (4-3.14) + 0.5 (0-0/0)
= 19.22%.
The real interest rate has moved in the direction to move inflation rate towards its target.
c. In scenario C, the output gap will be 20% compared to 0% in the base scenario.
Inflation gap is 0% in both the scenarios
Inflation rate is 3.14% and in scenario C, inflation rate is 2%.
Let's calculate the real interest rate. Real interest rate in the base scenario = 20% - 3.14%
= 16.86%.
Real interest rate in scenario C = 20% - 2% + 1.5 + 0.5 (3.14 - 3.14) + 0.5 (20-0/20)
= 20.15%.
Real interest rate in scenario C = 20% - 2% + 1.5 + 0.75 (3.14-3.14) + 0.25 (20-0/20) = 18.78%.
The new policy rule has changed the weight of the output gap in the Taylor Rule from 0.5 to 0.25.

Which of the following shows the correct solution steps and solution to 2×+ 7 = -11?
Answer:
x = - 9
Step-by-step explanation:
2x + 7 = - 11 ( subtract 7 from both sides )
2x = - 18 ( divide both sides by 2 )
x = - 9
The answer is:
x = -9
Work/explanation:
The point of equations is to find the variable's value by isolating it step-by-step.
For this equation, the variable is x.
To isolate it, I will perform a few operations.
First, I will subtract 7 from each side:
\(\sf{2x+7=-11}\)
\(\sf{2x=-11-7}\)
\(\sf{2x=-18}\)
Divide each side by 2
\(\sf{x=-9}\)
Hence, x = -9.

Answer:
x = 24°
Step-by-step explanation:
If two parallel lines are being intersected by the same line, the opposite inside angles are congruent. This means that ∠EFH should be equal to ∠JHF. However, we cannot set these angles equal because we do not know the value of ∠JHG.
Line IG is intersected by line HJ. This means the value of ∠JHG is 24° (180° - 156° = 24°). Know that we know this value, we can set up an equation to find "x".
∠EFH = 2x
∠JHG = 24°
∠GHF = x
∠EFH = ∠JHF <----- Opposite interior angles are equal
∠EFH = ∠JHG + ∠GHF <----- Break ∠JHF into 2 angles
2x = 24 + x <----- Insert values
x = 24 <----- Subtract x from both sides

In 2015, the average distance from Earth to the moon was about 3.74 x 105 km. The distance from Earth to Mars was about 9.25 x 107 km. How much farther is traveling from Earth to Mars than from Earth to the moon? Write your answer in scientific notation.
Traveling from Earth to Mars is approximately 9.249626 x 10^7 km farther than traveling from Earth to the moon.
Earth to Mars is compared to traveling from Earth to the moon, we need to calculate the difference between the distances.
The distance from Earth to the moon is approximately 3.74 x 10^5 km.
The distance from Earth to Mars is approximately 9.25 x 10^7 km.
To find the difference, we subtract the distance to the moon from the distance to Mars:
9.25 x 10^7 km - 3.74 x 10^5 km
To subtract these numbers, we need to make sure the exponents are the same. We can rewrite the distance to the moon in scientific notation with the same exponent as the distance to Mars:
3.74 x 10^5 km = 0.374 x 10^6 km (since 0.374 = 3.74 x 10^5 / 10^6)
Now we can perform the subtraction:
9.25 x 10^7 km - 0.374 x 10^6 km = 9.25 x 10^7 km - 0.374 x 10^6 km
To subtract, we subtract the coefficients and keep the same exponent:
9.25 x 10^7 km - 0.374 x 10^6 km = 9.25 x 10^7 - 0.374 x 10^6 km
Simplifying the subtraction:
9.25 x 10^7 - 0.374 x 10^6 km = 9.249626 x 10^7 km
Therefore, traveling from Earth to Mars is approximately 9.249626 x 10^7 km farther than traveling from Earth to the moon.
Scientific notation is a convenient way to express very large or very small numbers. It consists of a coefficient (a number between 1 and 10) multiplied by a power of 10 (exponent). It allows us to write and manipulate such numbers in a compact and standardized form.

Step-by-step explanation:
what to do: look at the equation and match each answer to the answer choice answers -the function has x-intercepts? -one vertical asymptote along the line where x always equals what number -one horizontal asymptote along the line where y always equals what number -how many holes? - there is a hole where the y intercept should be
Solution:
Given:
\(y=\frac{9x^2+81x}{x^3+8x^2-9x}\)The graph of the function is shown;
1) x-intercepts
From the graph of the equation, there is no x-intercept because the curve does not cut the x-axis at any point.
2) Vertical asymptote
The vertical asymptote is the vertical line the curve tends towards but does not touch.
From the graph, the vertical asymptote is at x = 1.
3) Horizontal asymptote
The horizontal asymptote is the horizontal line the curve tends towards but does not touch.
From the graph, the horizontal asymptote is at y = 0.
4) Hole
To get the hole, we get the common factor.
\(\begin{gathered} y=\frac{9x^2+81x}{x^3+8x^2-9x} \\ y=\frac{9x\left(x+9\right)}{x\left(x-1\right)\left(x+9\right)} \\ The\text{ common factors are;} \\ x\text{ and }x+9 \\ \\ Equate\text{ the common factors to zero} \\ Hence,\text{ there is a hole at}x=0 \\ \\ \\ \\ x+9=0 \\ Also,\text{ there is a hole at}x=-9 \\ \\ \\ Hence,\text{ cancelling out the common terms, the equation becomes;} \\ y=\frac{9}{(x-1)} \\ when\text{ x = 0,} \\ y=\frac{9}{0-1}=\frac{9}{-1} \\ y=-9 \\ Hence,\text{ hole is at }(0,-9) \\ \\ \\ Also,\text{ when x = -9} \\ y=\frac{9}{-9-1}=\frac{9}{-10} \\ Hence,\text{ hole is also at }(-9,-\frac{9}{10}) \end{gathered}\)Therefore, there are two holes.
A hole exists at (0,-9) which is where the y-intercept should be because the y-intercept usually exists at the point x = 0. Hence, there is a hole where the y-intercept should be. TRUE

z = (6.4 - 8.2)/1.1
Evaluate
z = -1.64
(b) Calculating the values of the z-scores 3.11 fluid ounceRecall that
z = (z - Mean)/Standard deviation
So when the score is 3.11, we have
z = (3.11 - 8.2)/1.1
