Answer:
Step-by-step explanation:
pyrhagoras theorem
a^2+b^2=c^2
( )^2+b^2=7^2
33+b^2=49
b^2=49-33
b=
b=4
therefore the length of the third side is 4

Y = 5x + 2
y = 3x
5x + 2 = 3x
- 5x - 5x
2 = -2x
-2 - 2
-1 = x
y = 3x
y = 3(-1)
y = -3
(x, y) = (-1, -3)
y = 3x
5x + 2 = 3x
- 5x - 5x
2 = -2x
-2 - 2
-1 = x
y = 3x
y = 3(-1)
y = -3
(x, y) = (-1, -3)
