Answer:
<u>f[g(x)] = f[x + 2] = 7(x + 2) + 13 = 7x + 7(2) + 13 = 7x + 14 + 13 = 7x + 27</u>
<u>f[g(x)] = 7x + 27</u>
r = 5y/8
Step-by-step explanation:
isolate the variable by dividing each side by factors that contain the variable.
10.5 cm^2
Area of a triangle = 1/2(L x H)
Reading from the diagram
length = 7 cm
height = 3 cm
therefore
Area of the triangle = 1/2( 7×3)
Area = 10.5 cm^2
(1,-1) and (4,-6)
midpoint:
x = (1 + 4)/2 = 5/2
y = (-1 - 6)/2 = -7/2
Midpoint (5/2, -7/2)
Answer
D.
(5/2, -7/2)
