Answer:
y=5x+42
subtract 5x from both sides
-5x+y=42
Step-by-step explanation:
subtract 5x from both sides
-5x+y=42
multiply by -1
5x-y=-42
In standard form, Ax+By=C, the variable A cannot be a negative. However, this is not an option so go with c.

Answer:
7
Step-by-step explanation:
we use Pythagorean theorem for solving x
a^2 + b^2 = c^2
c^2 - a^2 = b^2
(√58)^2 - (3)^2 = b^2
58 - 9 = b^2
49 = b^2
b = 7
