Answer: C
Step-by-step explanation:
πr^2 is how you find area
r=1/2(d)
r=1/2(12)
r=6
6^2=36
36π
Answer:
x = 3 and y = -3
Step-by-step explanation:
To start, let's double the first equation to get 6x + 2y = 12. Add this to the second equation to get 10x = 30, so x = 3 and y = -3.
Answer:
It takes 60 miles driven with company B for charge as much as company A
Step-by-step explanation:
Company A = $ 117 with unlimited mileage.
Company B = $ 75 + (m × $0,70)
Let's find the number of miles driven in company B for charge as much as company A:
$ 75 + (m × $ 0,70) = $ 117
m × $ 0,70 = $ 117 - $ 75
m = $ 42/ $0,70
m = 60 miles
Answer:

Step-by-step explanation:
Answer:
The answer is below
Step-by-step explanation:
The general form of a line is given by:
Ax + By + C = 0
The slope intercept form of a line is give by:
y = mx + b;
where m is the slope and b is the y intercept
Given a line with equation Ax + By + C = 0; the slope of the line can be gotten by representing in slope intercept form, hence it becomes:
By = -Ax - C
y = (-A/B)x - C/B
The slope is -A/B
For a line with equation Bx - Ay + C = 0:
Ay = Bx + C
y = (B/A)x + C/A
the slope is B/A
Two lines are said to be perpendicular if the product of the slopes is -1. Hence:
-A/B * B/A = -1; hence the two lines are perpendicular
