<h3>Answer: No, they are not perpendicular</h3>

Explanation:

Compare each equation to the form y = mx+b

m = slope

The first equation has slope -1/3 and the second equation has slope 1/3

The slopes do not multiply to -1, so the lines aren't perpendicular.

The slopes aren't equal, so the line aren't parallel either.

One number is 6 times another number. it is also 12 more than twice the other number. Find the numbers.
stepan [7]

The numbers are 3 and 18

Does 12cm,35cm,37cm equal a right triangle
velikii [3]
Start off by using the Pythagorean Theorem: a^2 + b^2 = c^2

12^2 + 35^2 = 37^2
144 + 1,225 = 1,369
1,369 = 1,369

If the left side equals the right side than it is a right triangle.

Your answer is: Yes 

Have an amazing day and stay hopeful!

Solve the inequality: -7y - 3x &lt; 21
SashulF [63]

Answer:

x>  -7/3y -7

Step-by-step explanation: -7y-3x<21

Step 1: Add 7y to both sides.

−3x−7y+7y<21+7y

−3x<7y+21

Step 2: Divide both sides by -3.

-3x/-3 < 7y+21/-3

x>-7/3y -7
