Yes, it is a right triangle.

Step-by-step explanation:

A right triangle follows the rules of 3,4,5 side lengths, in which 5 is the hypotenuse, 3 is the shortest side, and 4 is the opposite side.

Plug it into the equation. The equation you will use is:

(shortest side)² + (longer side)² = (hypotenuse)²

(9)² + (40)² = (41)²

Simplify. First, solve the power:

(81) + (1600) = (1681)

Simplify. Combine like terms:

(81 + 1600) = 1681

1681 = 1681 (True)

Yes, these sides can be used to make a right triangle.

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20
