Solve each of the following equations for x . Equation Solution x+7=18 x=11 5x+4=14 x=2 12−4x=−36 x=12 Organize each of the following equations to express P as a function of Q . Q as a function of P P as a function of Q Q=30−P Q=20−5P 6Q=14−2P

y=mx+b is the final answer!   : )

step-by-step explanation:

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

question: match the eqaution with its graph -8x - 5y = 40

answer: 8 x 5 = 40

x= absiss

y= orderly

so you have a proportional graph
