Answer:
74.05
Step-by-step explanation:
1st step: plug -3.5 in for all values of x
y = 1/5(-3.5) + 7(-3.5)^2 - 11
2nd step: follow the order of operations by doing (-3.5)^2 to get 12.25
y = 1/5(-3.5) + 7(12.25) -11
3rd step: multiply 1/5 and -3.5 to get -0.7
y = -0.7 + 7(12.25) -11
4th step: multiply 7 and 12.25 to get 85.75
y = -0.7 + 85.75 - 11
Lastly, now that all operations are either addition or subtraction, work left to right
y = 85.05 - 11.00
y = 74.05
