Step-by-step explanation:
8x+3y=18
subject y according y=mx+c
y=8/3x-6
(-9,-13)
substitute -9 to y=8/3x-6
-13=8/3×(-9)+c
11=c
y=8/3x+11
A
plug in x = -1 to both sides and you get 1 as the answer for both sides.
Answer:
1: x ^11
2: y ^12
3: x^ 7
Step-by-step explanation:
In 1 we give the sum
In 2 we give the multiple
In 3 we minus
