Is 21 because volume you add them up
Answer:
a
Step-by-step explanation:
2
Because -
2 x 12=12
2 x 13 = 36
2 x 42 = 84
Answer:
y=-2x-3
Step-by-step explanation:
Since the slope is -2, we can make an equation : y=-2x+b
Now plug in the point given to find b.
1=-2(-2)+b
1=4+b
b=-3
so, the equation is y=-2x-3
