Answer:
I think it's <u><em>A</em></u>
Step-by-step explanation:
You can multiply either the top or bottom equation by -1 so lets say you apply it to the bottom equation it’ll look like this:
-9x + 9y = 18
6x - 9y = 12
then the +9y and -9y will cancel out
-9x = 18
6x =12
then you add the two equations together
-3x = 30
divide both sides by -3
x = -10
Answer:
x=11 and the number of solutions is one solution
Step-by-step explanation:
The square root of 121 is 11. There are no other solutions, I believe.
Answer:
16 total meets
Step-by-step explanation:
it would break even at 8 wins and 8 loss so add them together and get 16 total meets.
Answer:
Solution given:
we have
y=5x-1
equating equation with y=mx+c
we get
slope [m]=5
we have
for parallel
slope are equal
So
<u>the</u><u> </u><u>required</u><u> </u><u>slope</u><u> </u><u>is</u><u> </u><u>5</u><u>.</u>
