X = oranges / y = apples

x - 2 = 2y and 0.5x - 0.5y = 4

x - 2 = 2y
   +2        +2
x = 2y + 2

0.5x - 0.5y = 4
2(0.5x - 0.5y = 4)
x - y = 8

Substitute 

(x) - y = 8
(2y + 2) - y = 8
3y + 2 = 8
     - 2       -2
3y = 6
y = 2

Substitute again

x = 2y + 2
x = 2(2) + 2
x = 4 + 2
x = 6

Hope this helps!

I need graph help plz ​
Likurg_2 [28]

Answer:

Step-by-step explanation:

Part A

x-intercepts of the graph → x = 0, 6

Maximum value of the graph → f(x) = 120

Part B

Increasing in the interval → 0 ≤ x ≤ 3

Decreasing in the interval → 3 < x ≤ 6

As the price of goods increase in the interval [0, 3], profit increases.

But in the price interval of (3, 6] profit of the company decreases.

Part C

Average rate of change of a function 'f' in the interval of x = a and x = b is given by,

Average rate of change = \frac{f(b)-f(a)}{b-a}

Therefore, average rate of change of the function in the interval x = 1 and x = 3 will be,

Average rate of change = \frac{f(3)-f(1)}{3-1}

                                         = \frac{120-60}{3-1}

                                         = 30
