In the formula 1= prt, find p when I is
$300, r is 4%, and t is 1 year.

P=$7,500

Step-by-step explanation:

The given formula is .

This is the simple interest formula

We want to find the principal, when I=$300

r=4% and t=1 year.

We substitute the values to obtain:

We multiply on the right to get:

Divide by 0.04 to get:

This gives

Therefore the principal is $7500  

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
