Jeff and his family are driving to visit his grandmother they have driven about 30 miles which is about 2/3 of the way how much farther do they have to go

 15 miles

Step-by-step explanation:

2/3 of the way is 30 miles

Let x represent the total distance to grandmother's house, then

Since the total distance is 45 and they have already driven 30 miles, there is 15 miles to go

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

50- 250 is correct i did that one too
