Answer:
D
Step-by-step explanation:
x+4y=8
4x+y=2
add
5x+5y=10
so system is
x+4y=8
5x+5y=10
Answer:
NONE
Step-by-step explanation:
(Sorry if I get something wrong, it’s straining my eyes to see what letter) 1. A 2. U 3. S 4. J 5. I 6. M 7. H 8. B 9. Y 10. L
To find where a coordinate is on a graph you need to start with the first number (x) (let’s say the coordinate is (2, -3), so 2) and find where it is ( you always find where the first number is on the x-axis and the second number on the y, remember that by x, y and x comes first.) Then, you need to find the second number (-3) then you need to find where they meet. So 2, -3 is on the letter I.
To find what coordinates a point that’s already been plotted is to see, for example, L, the two numbers that meet where L is are -4, -3, remember whatever was on the x axis comes first, -3, -4 is not the same.
Hopefully this makes sense, I don’t normally answer stuff.

Answer:
120 degrees! (line) or 300.
Step-by-step explanation:
All lines are 180 degrees, this triangle is congruent, so all sides are 60 degrees. 180 minus 60 is 120.
If it's a measure of a 360 degree angle, using 2 lines from the triangle, then you take 60 away from 360. A circle formed with that angle at it's radius would be 300 degrees.
