Answer:

<h2>B. y = -1.5x + 350</h2>

Step-by-step explanation:

Givens

  • Frederick earns $10 per hour at the grocery store.
  • He earns $8.50 per hour mowing lawns.
  • He worked 35 hours last week.

x represents hours mowing lawns, which make him earn $8.5 each.

y represents the total earnings, mowing lawns plus grocery store.

Now, we know that he worked 35 hours in total. So, if he worked x mowing lawns, then he worked 35-x hours in the grocery store, which represents +$10 per hour. So, this situation can be expressed as

y=8.50x+10(35-x)

Then, we solve the operations

y=8.50x+10(35-x)\\y=8.50x+350-10x\\y=-1.5x+350

Therefore, the right choice is B. y = -1.5x + 350

Openstudt what are the coordinates of the turning point for the function f(x) = (x − 2)3 + 1? (−2, −1) (−2, 1) (2, −1) (2, 1)
Dominik [7]

f(x) = (x - 2)^3 + 1

Find the derivative:-

f'(x) =   3(x -2)^2   This = 0 at the turning points:-

so 3(x - 2)^2 =  

giving x = 2 .  When x = 2     f(x)  =  3(2-2)^3 + 1 = 1

Answer is (2, 1)
