Answer:

Step-by-step explanation:

I don't completely understand what you were asking, but if you were counting by 7's, 91 would be after 84 instead of just 90.

On a map, 9 cm represents 15 miles. If the distance between two cities on the map is 15 cm, how many miles separate the cities?

torisob [31]

Answer:

15 cm on the map is equal to 25 miles.

Step-by-step explanation:

Given that,

On a map, 9 cm represents 15 miles.

The distance between two cities is 15 cm. We need to find the distance in miles.

9 cm = 15 miles

$1\ cm=\dfrac{15}{9}\ \miles$

So, 15 cm is equal to,

$15\ cm=\dfrac{15}{9}\times 15\ miles\\\\=25\ miles$

So, 15 cm on the map is equal to 25 miles.

What is the inverse of f(x)= cube root of x +2.

DiKsa [7]

F(x)= $\sqrt[3]{x+2}$
to solve for the inverse of a function you do 4 steps:
1. subsitute f(x) with y
2. switch y and x places
3. solve for y
4. subsitute y with f⁻¹(x)

so we have
f(x)= $\sqrt[3]{x+2}$
subsitute f(x) with y
y= $\sqrt[3]{x+2}$
switch x and y
x= $\sqrt[3]{y+2}$
solve for y

x= $\sqrt[3]{y+2}$
cube both sides
$x^{3}$ =y+2
subtract 2 from both sides
$x^{3}-2$ =y

subsitute y with f⁻¹(x)
f⁻¹(x)= $x^{3}-2$

the answer is f⁻¹(x)= $x^{3}-2$
