Since the parabola is connecting the points, it means that the points given are on the parabola or that the points are solutions of the parabola. Thus, when we substitute the points into the function, we should end up with the correct y-value.
To find the correct choice, let's test a point. An easy point to test I believe would be (-3, 0) because we should be getting 0 as a y-value. Let's test:




We can see that Choice B is the correct function, because it produces 0 when we substitute
. Thus, Choice B, or (x + 3)(x - 4) is the answer.
Answer:
The equation that can be used to determine the number of rounds that Emma golfs is:
x=(c-7.50)/6.25
Step-by-step explanation:
From the information given, the total amount Emma pays to go miniature golfing is equal to the price of the admission ticket plus the result of multiplying the price per round of golf for the number of rounds and according to this, the equation would be:
c=7.50+6.25x, where:
c is the total cost for Emma to go miniature golfing
x is the number of rounds
Now, you can solve for x to determine the equation that can be used to find the number of rounds that Emma golfs:
x=(c-7.50)/6.25
You can replace c with 26.25:
x=(26.25-7.50)/6.25
x=18.75/6.25
x=3
Using synthetic division to divide
x³ + 2x² - x - 2. Since (x + 1) is the factor, we can divide by -1. See the attached file for the synthetic division. After that, we are left with x² + x - 2. This can easily be factored into (x + 2)(x - 1). The remaining factors are (x + 2) and (x - 1).

Answer:
x = 4

Explanation:
We're solving the equation: -8=-(x+4)
Solve:
-8=-(x+4)
Distribute the negative to the variables in the parenthesis.
-8 = -x - 4
Add 4 to both sides
-4 = -x
Divide by -1
4 = x (same as x = 4)

Answer:
No, because it doesn't have a constant pattern and the ratios are nonequivalent
