Answer:
16. f(y-2) = 2(y-2)²-5
= 2(y²-4y+4)-5
= 2y²-8y+8-5
= 2y²-8y+3
17. f(a+h)-f(a) = 2(a+h)²-5-(2a²-5)
= 2(a²+2ah+h²)-5-2a²+5
= 2a²+4ah+h²-2a²
= h²+4ah
Answer:
x = 8
Step-by-step explanation:
200x - 100x + 57,600 = 60,000 - 200x
100x + 57,600 = 60,000 - 200x
300x = 2,400
x = 8

AB is a straight line and the angle of a straight line = 180°
so that means , solve for :

if you want to make sure of the answer, plug in in the equation:
The roots on the graph is basically the x-intercepts So if you see points that are on the x-axis then those are the roots.
Ex
x=0, x=-2 x=3 etc. <span />
Given :
A function, f(x) = -6 + 12
To Find :
The value of f(x) when x= -3, x= 0 and x=1.
Solution :
Given function is f(x) = -6 + 12 .
Simplifying above function, we get :
f(x) = 6
Now, the given function is independent of x.
So, for any value of x the the value of functions remains constant.
Hence, this is the required solution.
