Its called Pythagoras therom, A sq + B sq = C sq, if they give both legs you square them and then add them together, once you have that you square root both sides to get rid of the sq on C and you have your answer
Answer: y = 2x + 9
<u>Step-by-step explanation:</u>
slope(m) = 
= 
= 
= -2
Point-Slope formula: y - y₁ = m(x - x₁)
y - 5 = -2(x - 2)
y - 5 = -2x + 4
y = 2x + 9
( [72-60] / 72 )*100 = 50 / 3 = 16.7 %
Answer: A
Step-by-step explanation:
On a reflection through the x-axis, the x-coordinate of the point will not change, but the y-coordinate will be changed with a negative sign.
So, the reflection of the point is: (8, -7)
Therefore, Option(a)(8, -7) is true.
