Actual distance between two city = 40 miles
Step-by-step explanation:
Given sample size;
1 inch = 10 miles
Distance between two city = 4 inch
Find:
Actual distance between two city
Computation:
Actual distance between two city = Sample size of 1 inch in miles x Distance between two city
Actual distance between two city = 4 x 10
Actual distance between two city = 40 miles
The books are $5, and the magazines are $10. I’m not sure which way you want it explained but since magazines are twice the price of books, you can solve the equation 3b + 2b = 25. This gives you b=5 which you just multiply by 2 giving you the price of a magazine.
Answer: 5
Step-by-step explanation:
To find the inverse, interchange the variables and solve for

The invese switches x and y so basically
if
f(21)=z then f⁻¹(z)=21
therefor
f(z)=21 and f⁻¹(21)=z
basically solve for the value that makes the functino equal 21
21=6(x+2)-3
add 3 both sides
24=6(x+2)
divide by 6
4=x+2
minus 2
2=x
answer is 2
