498.12

Step-by-step explanation:

To find the answer you need to first find the area of the triangle which is simply where b is the base and h is the height when you plug the numbers in you get 96 for the area and to find the area of the semicircle you have to use the formula and you would get 128 pi which is 402.12 and when you add the numbers you get 498.12 as the area

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

x = 23.78
