Answer:
y = -0.2x - 5.8
Step-by-step explanation:
If a line is given in the form y = mx + b, the "m" is the slope.
For the line given y = 5x, the slope is 5
The line that is perpendicular to this will have slope that is "negative reciprocal of that".
So, the perpendicular line will have slope of 
So, the Perpendicular Line will have equation:
y = -1/5x + b
Let's find b by replacing x with 6 and y with -7 [the point given]. So we have:

So the equation of perpendicular line = y = -0.2x - 5.8
Answer:
Your answer is -3
Step-by-step explanation:
We know your answer is going to be the answer because 8 is a bigger number than 5, so you take 5 away from (-8)
Which leaves you with -3

Answer:
Acute angles.
Step-by-step explanation:
Acute angles are from 0-90 degrees.
Hope this helps :)
Step-by-step explanation:
f(x) = 2x² + 9
f(5) = 2(5)² + 9
= 2(25) + 9
= 50 + 9
= 59
