Which ordered pair is a solution to the system of equations 4x-y=10 y=2x-2

A.(-1,2)
B.(-3,0)
C.(4,6)
D.(4,0)

C

Step-by-step explanation:

Substitute the coordinates of each point into the equations and if true then the point is a solution.

A (- 1, 2 )

4(- 1) - 2 = - 4 - 2 = - 6 ≠ 10 ← not a solution

B (- 3, 0 )

4(- 3) - 0 = - 12 ≠ 10 ← not a solution

C (4, 6 )

4(4) - 6 = 16 - 6 = 10 and

2(4) - 2 = 8 - 2 = 6

Both equations are true, thus (4, 6) is a solution to the system of equations

D (4, 0 )

4(4) - 0 = 16 ≠ 10 ← not a solution

Step-by-step explanation:

hello :

C.(4,6) you can verify : 4(4)-6=10  ..right

                                   6=2(4)-2..right

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
