Subtract the fee from the total:
131- 35.50 = 95.50
Now divide that by the price per mile:
95.50/ 0.40 = 238.75
They drove 238.74 miles
The answer is x=22 because you just have to add the two equations together and then solve for 8x+4=180
Tan(58)=10/x
x=10/tan(58)
x= 6.2
Replace all the x values with -3
f(-3)=-2(-3)^2+5(-3)
f(-3)=2(9)-15
f(-3)=18-15
f(-3)=3
Hope I helped :)
