-2(3(3)-4)+6(2(3)-7) = -16.
X= 8
Y= -7
If you use elimination:
–3y–4x=–11
3y–5x=–61
Add the two equations and get
–9x=–72
Divide by –9 on both sides
X=8
Substitute 8 in for x
–3y–4(8)=–11
Simplify
–3y–32=–11
Add 32 on both sides
–3y=21
Divide by –3 on both sides
Y=–7
Answer:
A
Step-by-step explanation:
If two lines are perpendicular, the slopes are the negative reciprocals of each other. If one slope is 5, then the other is -1/5.
The answer would be 21 I believe
