An audio books club charges an initial joining fee of $15.00. the cost per audio book is $12.00. the graph shows the cost of belonging to the club as a function of audio books purchased. how will the graph change if the cost per audio book goes up by $1.00?

The y intercept would remain the same but the slope would increase .

Step-by-step explanation:

An audio books club charges an initial joining fee of $15.00. The cost per audio book is $12.00. The graph shows the cost of belonging to the club as a function of audio books purchased.

The graph is drawn with number of audio books along x axis and the total charges along y axis.

The equation is : y = 12x + 15

Now we are going to increase the cost of audio book by $1.00

Then the total charge would also increase.The y intercept would remain the same but the slope would increase .

The new equation is : y = 13x + 15

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

x=5
