Answer:

Answer:

(x,y) --> (x+4, y-5)

Step-by-step explanation:

A is correct. B can be represented as x+4, y - 5 because the x values shifted 4 to the right (a positive shift so x+4) and the y values shifted 5 down (a negative shift so y-5)

For the graphed exponential equation, calculate the average rate of change from x = −3 to x = 0. graph of f of x equals 0.5 to the x power, minus 6.

Answers

The average rate of change will be negative 7 / 3.

How to find the average rate of change of something?

Let the thing that is changing be y and the thing with which the rate is being compared is x, then we have the average rate of change of y as x changes as:

Average rate = (y₂ - y₁) / (x₂ - x₁)

The exponential function is given below.

f(x) = (0.5)ˣ - 6

Then the average rate of change will be

Average rate = [f(0) - f(-3)] / [0 - (-3)]

Average rate = [(0.5⁰ - 6) - (0.5⁻³ - 6)] / 3

Average rate = [1 - 6 - 8 + 6] / 3

Average rate = - 7 / 3

The fountain contains 20 pennies and 9 dimes. A coin is randomly taken and not replaced. A second coin is randomly taken. What is the probability that both coins are pennies?

Answers

Well, the first coin has chance $(20)/(29)$ to be a penny. When it is a penny, the only valid case (the other case gives 0 for the multiplications later, so it is ignored) gives $(19)/(28)$ chance for the second one to be a penny. The result is $(20*19)/(29*28)$ , which is $(95)/(203)$ , or about 46.80% (rounded to the first 2 decimals)

Answer:

9 dimes

When factored completely, the expression p^4-81 is equivalent to what?

Answers

differnce of 2 pefect squares
a^2-b^2=(a-b)(a+b)
(p^2)^2-9^2=(p^2-9)(p^2+9)

p^2-9=(p-3)(p+3)

factored is
(p-3)(p+3)(p^2+9)

Can anyone please help with this question

Answers

so 4(x+5)=x+8
first we distribute
using the distributive property of multiplication which is a(b+c)=(ab)+(ac)

4(x+5) is also (4x)+(4(5))=4x+20

4x+20=x+8
subtract x from both sides
3x+20=8
subtract 20 from both sides
3x=-12
divide both sides by 3
x=-4

4(x+5)=x+8
4x+4*5=x+8
4x+20=x+8
4x-x+20=x+8-x
3x+20-20=8-20
3x=-12
3x/3=(-12)/3
x=-4

Follow the directions to solve the system of equations by elimination.8x + 7y = 39
4x – 14y = –68

Answers

To solve a system of equation by elimination, the coefficients of the same variable of both equations must be equal. In this case, let's choose y.
In order to make the coefficient of y of the second equation be equal to 7, we divide it by 2. Resulting to:
2x - 7y = -34

Next, add the two solutions so that the y term is eliminated. The result is:
10x = 5
Then solve for x
x = 1/2

Substitute x to either of the solution to solve for y. The result is:
y = 5

Final answer:

The solution to the system of equations 8x + 7y = 39 and 4x – 14y = -68 via elimination is x = 0.5 and y = 5.

Explanation:

The two given equations are 8x + 7y = 39 and 4x – 14y = -68. The method for solving this is elimination.

First, modify the second equation by multiplying every term by 2.
This will give 8x - 28y = -136.
Now, you have two equations 8x + 7y = 39 and 8x - 28y = -136 that can be combined by subtraction: 8x - 8x + 7y - (-28y) = 39 - (-136).
Simplification gives 35y = 175, so y = 5.
Substituting y = 5 into the first equation, 8x + 7*5 = 39, which simplifies to 8x + 35 = 39, and then to 8x = 4, so x = 0.5.
