Answer:
The correct answer would be 
Step-by-step explanation:
given 
we want to solve for a
How?
We can do this by using basic algebra ( isolating the variable (a ))
Step 1 subtract 
from each side
now we have 
step 2 take the square root of each side
we're left with
Hence your answer is A
How much trophies does Jared have(
the only thing you need to do is separate m:
2/7m= 3/14 + 1/7
2/7m= 5/14
m= (5/14)/(2/7)
m= 5/14 × 7/2
m= 35/28
m= 5/4
Remember, rise/run is the easiest way to determine slope
y=mx+b is form
mx is slope, whilst b is y int
so, answer? y=-3x-2
Or A.
