Mistake D. The response from seniors was reversed.
Didn't answer all because I got lazy and I think you should try and do the rest yourself. Did this in 5 mins, try putting more effort into your homework. This is basic mathematics.
Answer:
-7
Step-by-step explanation:
We first are going to flip the equation around.
So instead of 9 times x = -36 we'll do 36/9. 36/9 = -7.
Also you will kind of know it will be a negative number from the beginning since it's -36.
I don't know if that last part makes any sense, but I hope this helps you!
Answer:
the first one
Step-by-step explanation:
remember, in a function, x can only have one y, whereas y can have more than one x
Find the soluiton
2x+2y=16
3x-y=4
x+y=8
<u>3x-y=4+</u>
4x=12
x=3
3(3)-y=4
9-y=4
y=5
(3,5)
test them to see if get true statment
obviously the first equatons of 1,2,4 work
1 doesn't work
2, works
4. doesn't work
2 is the same as the first except both euations are just doubled
answer is 2
