The expression 1/2 bh gives the area of a triangle where b is the base of the triangle and h is the height of the triangle. what is the area of a triangle with a base of 7 cm and a height of 4 cm. ?

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
