The Amador family pays $7.50 per thousand cubic feet of natural gas. The total cost, t, varies directly as the number of thousand cubic feet to natural gas, g, used. Draw a graph that shows the proportional relationship between t and g.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

30,40,50 is correct answer

1. a^4+8a^3+24a^2+32a+16

2.y^8+8y^7+28y^6+56y^5+70y^4+56y^3+28y^2+8y+1

3.x^6-3x^4y^2+3x^2y^4-y^6
