Put the values of x to the equations of the functions:
1. f(9) → x = 9; f(x) = -3x + 10
f(9) = -3(9) + 10 = -27 + 10 = -17
2. f(-2) → x = -2; f(x) = 4x - 1
f(-2) = 4(-2) - 1 = -8 - 1 = -9
3. f(-5) → x = -5; f(x) = -2x + 8
f(-5) = -2(-5) + 8 = 10 + 8 = 18
Answer:
Each plane cuts the other two in a line and they form a prismatic surface. ... The second and third planes are coincident and the first is cuting them, therefore the three planes intersect in a line.

Answer:
C = 6.28 in.
A = 3.14 in.^2
Step-by-step explanation:
C = (pi)d
C = 3.14 * 2 in.
C = 6.28 in.
A = (pi)r^2
r = d/2 = 2 in./2 = 1 in.
A = 3.14 * (1 in.^2)
A = 3.14 in.^2
