Apainter can paint 350 square feet in 1.25 hours. what is the painting rate in square feet per hour?

We are given a painter can paint 350 square feet in 1.25 hours.

We want to figure out the painting rate in square feet per hour. “Per hour” means for every 1 hour.

To find this, an equation like 350 = 1.25h (h for hours) can be set up. To solve, the only thing we need to do is divide by 1.25 to get h alone:

350/1.25 = 1.25h/1.25 or 280 = h

The painter can paint 280 square feet per 1 hour.

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
