If 39 is 15% of a number, what is that number? How did you find your answer?

260

Step-by-step explanation:

There are a few ways to solve this, but an easy to understand one is that 39=15%, therefore 13=5%, as it is taking 1/3 of each number. Then to get to 100% we would need to multiply 13=5% by 20 to get 260=100%

i need a picure

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
