Answer:
251.047804213 miles
Step-by-step explanation:
c1 t=3.5+1 speed 40 mph
c2 t=3.5 speed 50 mph
c1 40 *4.5= 180
c2 50 *3.5= 175
a^2+ b^2= c^2
180^2+175^2=c^2
32400+30625=c^2
63025=c^2
251.047804213=c
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

Isolate the variable y
subtract x both sides

Divide by 2 both sides

The solution of the inequality is the shaded area above the dashed line

The slope of the dashed line is negative
The y-intercept of the dashed line is (0,2)
The x-intercept of the dashed line is (4,0)
therefore
The graph in the attached figure
