The ratio 1:2 means there are twice as many dimes as there are quarters. An expression could be n=2d, n being number of quarters, d being number of dimes.
Answer:
216 marbles bought altogether
Step-by-step explanation:
small m- 10
large m- 8
10×12+8×12=
120+96
= 216
F⁻¹(x) stands for the invers of function f(x). The inverse of f(x) is equal to x. We need to solve for x.
solve for x
f(x) = 2x + 2
2x + 2 = f(x)
2x = f(x) - 2
x =

f⁻¹(x) =

Determine the value of f⁻¹(x) when x = 4
f⁻¹(x) =

f⁻¹(4) =

f⁻¹(4) =

f⁻¹(4) = 1
When x = 4, the value of f⁻¹(x) is equal to 1
