x=2
Step-by-step explanation:
10x2=20
20+1=21
Simplify the exponents
3-2=1 therefore it should be 1/7 the third answer. Hope that helps
Answer:
Not solutions.
Step-by-step explanation:
-5x+6y=-5
6y=-5+5x
6y=5x-5
y=5/6x-5/6
-5/6 is about -0.833
And the slope is 5/6.
So for every x there is 5/6y.
This means (1, 4) won't work cause it's too low.
Also 5/6*6=5. this is too low too.
So they aren't solutions.
