Use the substitution method to solve the system of equations. choose the correct ordered pair. 2x - y = 103x - 2y = 8

crimeas [40]

$2x-y=10\Rightarrow 2x-10=y \\ 
\Longrightarrow 3x-2y=8\Rightarrow 3x-2(2x-10)=8 \\ 
3x-4x+20=8 \\ -x=8-20=-12 \\ x=12 \\ \\ y=2(12)-10=24-10 \\ y=14 \\ \\ (x,y)=(12,14)$

Answer:

d. AB = 54

Step-by-step explanation:

The triangle is isosceles, so AB = AC.

(4x +6) = (5x -6)

12 = x . . . . . . . . . . . . add 6-4x to both sides

Then the length of AB is ...

AB = 4x +6 = 4(12) +6 = 48 +6

AB = 54
