Answer:
If you simplify the equation, you will get, 
Step-by-step explanation:
You have to combine like terms.
and
are like terms, so you add them together.
Answer:
y=2x+4
Step-by-step explanation:
slope=2 as parallel lines have the same slope
y=2x+b , if x=2 then y=8 , so 2x2+b=8
so, b=4
Therefore the equation is y=2x+4
Answer:
y=1, x=-1
Step-by-step explanation:
I used substitution **I'm not sure this is right but this is what I got!!!***
Answer:
B
Step-by-step explanation:
if an angle is congruent, it is the same measurement
A=(V-V₀)/t
a=(220-88)/3=44 ft/s²
Acceleration is 44 ft/s²
