when
y
=
9
x
=
k
y
⇒

Step-by-step explanation:
A function is increasing if it "points upwards".
Think that you have two inputs (think of them as being very close to each other). A function is increasing if
So, smaller input, smaller output.
So:
- In the first segment on the left, the function is decreasing: if you move with little steps rightwards, the output will get smaller and smaller (the function points to the right bottom)
- In the second segment, the line is constant (it's horizontal). This means that even if you consider a larger input, the output reimains the same
- In the third segment, the function is increasing: if you consider a larger input, the output will be larger as well: the function points to the top right.
- In the fourth segment, the function is decreasing again (look at the first bullet point)
So, the function is increasing in the third segment, which is delimited by
-2y - 2y - 8 = -4
Move the -8 to the -4, and that makes
-2y -2y = 4
Add the -2ys together and that makes
-4y = 4
Then divide by -4, and you will get your answer of
y= -1
Answer:
g(q) =
Step-by-step explanation:
Given
- 7q + 12r = 3q - 4r
Rearrange making r the subject
Add 7q to both sides
12r = 10q - 4r ( add 4r to both sides )
16r = 10q ( divide both sides by 16 )
r = = , thus
g(q) =
