Carl drove to his grandmother’s house. He drove for 6 hours and averaged a speed of 55 miles per hour. At the end of 6 hours he still had 90 miles to go until he reached his grandmother’s house. What was the distance of his trip?

420 miles

Step-by-step explanation:

Distance traveled per hour = 55 miles

Distance traveled in 6 hours = 55 * 6 = 330 miles

Distance of the trip = 330 + 90  = 420 miles

all it means is function 3

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
