Just plug stuff in
(0, 32)
(100, 212)
(-20, -4)
(10, 50)
50. That is the expected number. Because 100 divided by 2 equals 50.

Answer:
Step-by-step explanation:
Differentiate using the power rule
(a) = na
Given
f(x) = - = - , then
f'(x) = - 1 × - 1 × = =
10x+3y=43
-9x-y=-20
From second equation,
y=-9x+20
Substitute third equation into first equation,
10x+3(-9x+20)=43
10x-27x+60=43
-17x=43-60
-17x=-17
x=1
y= -9+20= 11
Option B
