Which statement is not used to prove that ΔABC is similar to ΔADE? AC is a transversal line passing ED and CB.
Angle A is congruent to itself, due to the reflexive property.
Segments ED and CB are parallel.
The sum of angles A and B are supplementary to angle C.

360/29

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
