If she did not reach her goal then
miles she drove must be less than 385
or
miles she drove<385
so rate=55 miles per hour
so
miles driven=h times 55
subsitute
55 times h<385
divide both sides by 55
h<7
she drove less than 7 hours
inequality=55h<385
h<7
Step-by-step explanation:
Abby’s Expression:
Double m, giving 2m. She then takes 20% of the result, which we can write 0.2(2m). Finally she subtracts this from 2m, giving 2m−(0.2)2m
2m − (0.2)2m
Renato’s Expression:
Divide m by 5, giving m ÷ 5 = m/5, and then multiplies the result by 8, giving:
8(m/5)
The axis of symmetry is x=-1
