Answer:
x = 6
Step-by-step explanation:
These are supplementary angles.
This means that the angles add up to 180 degrees.
The first thing we can do is set 6y equal to 90, because the little red box means that is 90 degrees.
6y = 90
y = 15
Now that we have found y we can solve for x.
Plug in the y to the 5x + 4y
5x + 4(15)
5x + 60
We can set this equal to 90 again
5x + 60 = 90
5x = 30
x = 6
Therefore x is equal to 6.

Step-by-step explanation: 1. Bree= 2x+3
2. Tessa= x
3. 2x+3=23
4. 2x=26
5.x=13
Tessa's Age is 13 Years old.
Yes it’s a function bc if u graph it no two points are on the same x or y point so it passes the vertical line test making it a function
(-4-(-4))/(2-8) = 0/-6 = 0 = zero slope
Your answer would be D I took the quiz just now and got a 100% :)
