Answer:
Option C 
Step-by-step explanation:
step 1
Find the slope of AB
we have
A(-3,-1) and B(4,4)
The slope m is equal to


step 2
Find the slope of BC
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
so

we have

substitute


step 3
Find the equation of the line into slope point form

we have


substitute

Multiply by 5 both sides



Multiply by -1 both sides

Answer:
x ≥ 4
Step-by-step explanation:
Multiply to remove the fraction, then set equal to 0 and solve.
Inequality Form:
x ≥ 4
Interval Notation:

The graph will be a horizontal line.
Explanation:
In this number line the solution set that's graphed is all numbers less than 1. It doesn't include 1 because that point is graphed with an empty circle.
Answer:
x < 1
The answer is 40. 5/9 of 72 is 40
Answer:
A & D are correct
Step-by-step explanation:
to solve for 'x':
4x + 16 = 180
4x = 164
x = 41
m∡A = 2(41)+1 = 83°
m∡B = 41°
m∡C = 41+15 = 56°
