No, it is not a function.
Step-by-step explanation:
Answer:
She must work at least 7 hours. All possible values are 7, 8, 9, 10
Step-by-step explanation:
14 - 4 = 10
4($7)=$28
$130-$28=$102
$102÷$15=6.8
$15x7=$105
$105+$28=$133
$15x8=$120
$120+$28=$148
$15x9=$135
$135+$28=$163
$15x10=$150
$150+$28=$178
Answer: 24
Step-by-step explanation:
Colleen painted 7 windows, some of which were her mother's.
Her dad painted 7+1 (8) windows, and that is twice as much as what her mother was supposed to do. Her mother was supposed to do 4 windows. That means Colleen's share was 3 windows.
If all the kids had to do an equal amount of windows, than each kid had to do 3 windows.
8+7+3+3+3=24
When a shape is rotated, it must be rotated through a point.
- <em>90 degrees counterclockwise rotation negates the y-coordinates, and then swap the x and y-coordinates</em>
- <em>Chanel is incorrect</em>
The rule of 90 degrees counterclockwise is:

This means that:
- <em>The y-coordinate is negated</em>
- <em>Then the y and x coordinates are swapped</em>
<em />
However, Charlies transformation is incorrect.
- This is so because, the shape was not rotated, but instead it was reflected across the x-axis.
- Then, the shape was dilated
Using points L and Q

When L is reflected across the x-axis.
The rule is:

So, we have:

Next, it is dilated by 2.
The rule of this is:

So, we have:


From the diagram, the coordinate of Q is:

Same as the calculated point
Hence, Chanel is incorrect
