If line b is perpendicular to line a, and line c is perpendicular to line a, what is the slope of line c?mc = _____

Answers

Answer 1

Answer:

we know that

If line b is perpendicular to line a, and line c is perpendicular to line a,

then

line b and line c are parallel

and two lines parallel have the same slope

Find the slope of the line b

Let

$A(-3,-2)\nB(2,3)$

The formula to calculate the slope between two points is equal to

$m=((y2-y1))/((x2-x1))$

$(x1,y1)=(-3,-2)\n(x2,y2)=(2,3)$

substitute

$m=((3+2))/((2+3))$

$m=((5))/((5))$

$m=1$

therefore

the answer is

the slope of the line c is

$mc=1$

Answer 2

Answer:

If two lines are perpendicular, then the product of the slope is -1.

Thus, the slope of line c is m which is the same as line b.

What is the linear system?

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

Line b is perpendicular to line a, and line c is perpendicular to line a.

To find

The slope of line c.

We know that the slope theorem

If two lines are perpendicular, then the product of the slope is -1.

Let the slope of line b be m, then the slope of line a will be .

$\rm m_am_b = -1$

Then

$\rm m_a = -1/m_b$

Then the slope of line c will be.

$\rm m_am_c = -1$

Then

$\rm m_c = m_b$

Thus, the slope of line c is m which is the same as line b.

You read 50 pages in an hour. Your sister reads 40 pages in an hour. Explain how to find out how many more pages you read than your sister reads in 1/2 hour?A. I know that 50 • 40 = 2,000, so I read 1,000 more pages than my sister reads in 1/2 hour.
B. I know that 50 ÷ 40 = 5454, 5 ÷ 4 = 1 1/4, so I read 1 1/4 more pages than my sister reads in 1/2 hour.
C. Because I read 10 more pages than my sister reads in 1 hour, I read 5 more pages in 1/2 hour.
D. Since 5 • 4 = 20, I read 20 more pages than my sister reads in 1/2 one half hour.

what is x??

Answers

Hi there!

Answer:

x=-1

Step-by-step explanation:

Distributive property: ⇒ a(b+c)=ab+ac

5x-2=-7

add 2 both sides of an equation.

5x-2+-7+2

simplify.

5x=-5

divide by 5 both sides of an equation.

5x/5=-5/5

simplify

-5/5=-1

x=-1

Hope this helps!
