Answer:

The value of f(3)=12.4

Step-by-step explanation:

Average rate of change = 3.4

Interval: -2 < x < 3

f(-2) = 9

We need to find f(3)

The formula used to calculate Average rate of change is: Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}

here we have a=-2 and b=3

Now finding f(3)

Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}\\3.4=\frac{f(3)-f(-2)}{3-2} \\3.4=\frac{f(3)-9}{1}\\3.4=f(3)-9\\f(3)=3.4+9\\f(3)=12.4

So, The value of f(3)=12.4

A restaurant manager wants to purchase 200 sets of dishes. One design costs ​$10 per​ set, while another costs ​$35 per set. If
pogonyaev
X = 10 per set dishes, and y = 35 per set dishes

x + y = 200....x = 200 - y
10x + 35y = 4250

10(200 - y) + 35y = 4250
2000 - 10y + 35y = 4250
-10y + 35y = 4250 - 2000
25y = 2250
y = 2250/25
y = 90 <=== he got 90 of the $ 35 dishes

x + y = 200
x + 90 = 200
x = 200 - 90
x = 110 <=== he got 110 of the $ 10 dishes
