Enter your answer in the box.

ft
A triangle with vertices labeled as A, B, and C. Side B C is base. Sides A B and A C contain points D and E, respectively. A line segment is drawn from D to E. Side A D is labeled 8 feet. Side D B is labeled 2 feet. Side A E is labeled 4 feet. Base B C and line segment D E are labeled with single arrowhead pointing the same direction.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
