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
