If (a, - 7) is a solution to the equation 8a =-3b – 5, what is a? O -17
O 17
O 2
O 8

C

Step-by-step explanation:

b is the y value of the equation.

8a = -3b - 5         Let b = - 7

8a = -3*-7 - 5       Combine

8a = 21 - 5            Combine the right again.

8a = 16                 Divide by 8

8a/8 = 16/8

a = 2

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
