Answer:
8
Step-by-step explanation:
We start by getting the coordinate of the dilated point
what we simply have to do
here is to multiply the coordinates of the initial given point by the dilation factor
Mathematically, we have this as ;
(4,1) to (8,2)
So the x-coordinate of the endpoint is 8
Answer:
31
Step-by-step explanation:
To rationalise 7 + 3 , multiply by its conjugate
The conjugate of 7 + 3 is 7 - 3 , then
(7 + 3)(7 - 3) ← expand using FOIL
= 49 - 21 - 21 - (3)²
= 49 - 18
= 31
You add 3x plus 2x to get you 5x then -7 plus 10 to get you positive 3
5x + 3 is the final answer

(-1,5)</u></h2><h2><u>
(-4,-8)</u></h2>
Step-by-step explanation:
When an inequality is graphed, the solutions will be shaded in a color. \
On this graph, it is shaded blue.
First we want to put all the points on the graph. During this step, it does not mater if the point is in the blue or not.
Now that we have all 8 points plotted, we can begin elimination.
For this step, we will cross out or eliminate any points in the white.
Any points in the blue, will be correct
After doing this step, you should have the answers <u>(0,0), (4,9), (-1,5), (-4,-8)</u>
So those are the correct answers
