Answer:
X=5, Y=0
Step-by-step explanation:
-9Y +4X -20=0
-7Y+16X-80=0
1. We can multiply the first equation by 4. This will equal to -36Y +16X-80=0.
-36Y +16X -80 =0
-7Y+16X-80=0
2. We can subtract these two equations.
-36Y +16X -80 =0
-7Y+16X-80=0
We will get -29Y =0. Y=0.
3. Then we can substitute y into the first equation. -9(0) +4x-20 =0. 4x=20. x=5
X=5, Y=0
Answer:
perpendicular
Step-by-step explanation:
They will intersect at a 90 degree angle as x= is vertical and y= is horizontal
Answer:
The answer is 62.17
Step-by-step explanation:
Because 3 in the thousandths is not equal to or greater than 5
3= 3 thirds + 3 thirds + 3 thirds = 9 thirds
2/3 = 2 thirds
9 + 2 = 11 thirds. (11/3)
