C) Ms. Applewhite needs to drive 210 miles to get to Washington, D. C. She has already driven 60 miles. If she drives 30 miles per hour, how many more hours will she have to drive? Write and solve an equation.

Answer is in the photo. I couldn't attach it here, but uploaded it to a file hosting. link below! Good Luck!

5 hours

Step-by-step explanation:

210-60=150

150/30=5 hours

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
