You did not include the choices. However, I answered one that just included them. I've included the possible answers below and then the correct answers. 

<span>A multiple of Equation 1. 
B. The sum of Equation 1 and Equation 2 
C. An equation that replaces only the coefficient of x with the sum of the coefficients of x in Equation 1 and Equation 2. 
D. An equation that replaces only the coefficient of y with the sum of the coefficients of y in Equation 1 and Equation 2. 
E. The sum of a multiple of Equation 1 and Equation 2.

</span>A, B and E.

Adding and multiplying the terms allow them to keep working. However, you must make sure that each variable is changed each time. Not just one as in C and D.

A runner warmed up for 10 minutes and then takes seven minutes to run each mile. The total time after r miles is 45 minutes how
scoundrel [369]
So our equation to find this can be represented by 7x + 10 = 45.
(x representing miles run)
Just solve for x!

Subtract the 10 from both sides, you've got
 7x = 35
And now to isolate the x, we divide both sides by 7.
Now we're left with just
x = 5!

We can check this by substituting 5 as x in our equation.
7x x 5 + 10 = 45
45 = 45
It's right!

So the runner ran 5 miles total.

Hope this helps!
If I skimmed over this too much, let me know and I'll try to explain the best that I can.

What is the y-value of the vertex 4x^2 +8x-8
galina1969 [7]

Answer:

-12

Step-by-step explanation:

Here the coefficients a, b and c are 4, 8 and -8 respectively.

                                                                     -b

A formula for the axis of symmetry is x = -------

                                                                      2a

                                 -8

... which yields x = --------- = -1

                                2(4)

Evaluating f(x) = 4x^2 + 8x - 8 at x = -1 yields   f(-1) = 4(-1)^2 + 8(-1) - 8 = -12.

The y-value of the vertex is -12.  Note that the vertex lies right smack on the axis of symmetry.
