Answer:
450+70x
Step-by-step explanation:
x is the number of months and 450 is the actual amount of money in his bank account
Answer: The answer would be f^-1 (x) = x/2 - 3/2
Answer:
f(4) = -11
Step-by-step explanation:
Plug in 4 for x: Note that x = 4.
f(x) = -2x - 3
f(4) = -2(4) - 3
Remember to follow PEMDAS. First, solve the multiplication, then subtract:
f(4) = (-2 * 4) - 3
f(4) = (-8) - 3
f(4) = -11
f(4) = -11 is your answer.

a trapezoid
equation for area = h(a +b) ÷ 2
so you sub that in
8(9 +21) ÷ 2 = 8 × 30 ÷ 2 = 120
so the area is 120cm
8
A trapezoid
equation for area = h(a +b) ÷ 2
so you sub that in
6(9 + 5 ) ÷ 2 = 6 × 14 ÷ 2 = 42
So the answer is 42 inches
9
A kite
equation for area = p× q ÷ 2
so you sub that in
(3+3)×(4.5+6.5) ÷ 2 = 6×11÷2 = 3
So the answer is 33 cm
