Answer:
144&36
126&54
21&159
Step-by-step explanation:
Supplementary means angles that add up to 180 degrees
Since these angles add up to 180 degrees, they are therefore supplementary
Hello!
This question is an example of function notation. Function notation is basically f(x) , said as "f of x". To solve this problem, you need to substitute x = 2 into each x-value in this equation. F(2) is written as function notation, while x = 2 is not.
F(2) = 4x² - 3x + 5
F(2) = 4(2)² - 3(2) + 5
F(2) = 4(4) - 6 + 5
F(2) = 16 - 6 + 5
F(2) = 15
Therefore, the value of F(2) is 15.
Answer:
We will add 64 to both sides.
x=8±√20
Step-by-step explanation:
Here we are given the equation:

Now we take half of the coefficient of x and add it to x.
Coefficient of x is 16, half of 16 is 8.
Also we add square of 8 to both sides.
So new equation becomes:

Completing the square:

NOw let us simplify it to get the value of x.
Taking square root on both sides:

Bringing 8 to the right side:
x=8±√20
Answer:

Step-by-step explanation:
Given:
Interval, [0, 4]
Required:
Average range of change over [0, 4]
SOLUTION:
Find f(0) and f(4) from the graph:
(when x = 0, y = 0)
(when x = 4, y = 3)
Average rate of change = 
Where,


Plug in the values into the formula for average rate of change.


Average rate of change 
The slope would be 0 and it is a straight line line
