Which system of equations is represented by the matrix below? 1 5-6
0 317
O A. y + 5x = -6
3x = 17
O B. x + 5y = -6
x + 3y = 17
O
C. x+ 5y = -6
3y = 17

C. x+ 5y = -6

3y = 17

This is the correct answer.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
