Question

Please Help Me

Answer 1

i think that is it

Answer 2

really, yay okay...I just guessed on that one

Answer 3

whats your guess??

Answer 4

C?

Answer 5

well first, what can you use for x and y?? to make them true

Answer 6

0 and -3?

Answer 7

1st one is wrong

Answer 8

no, but here.. the only solution i have got so far was x=3 and y=1. plug those numbers in for the variables and tell me if they are right

Answer 9

3*3-9*1=0
-3+3*1=0

Answer 10

x + y = 6
x = y + 5
so sub in y + 5 for x back into the 1st equation
(y + 5) + y = 6
===============
-x + 3y = -3
3y = x - 3
y = 1/3x - 1...slope is 1/3...y intercept is -1

and then the other equation
3x - 9y = 0
-9y = -3x + 0
y = 1/3x + 0....slope is 1/3...y intercept is 0

since they have the same slope, but different y intercepts, this means they are parallel and there is no solution

Answer 11

thank you...can you help me with my other problems too?
