As a membership fee a health club charges a one time amount of $40 and charges $25 for each month. The total fee after m months
ICE Princess25 [194]
First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.
To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.
240 = 25x + 40
subtract 40 from each side
200= 25x
divide by 25
8 = x
8 months

Isn't A B and D correct?
faust18 [17]

Answer:

I think the answer is B.

Step-by-step explanation:

I'm just going by how it looks but I am pretty sure that <em>n</em> is -0.5 and <em>m</em> is 2.5. Therefore, if you add -0.5 + 2.5 it equals 2.0.

Graph 6x-2y=2 ,9x-3y=1
enot [183]

It's a linear function. We need only two points to draw a graph.

We choose any values of x and calculate the value of y.

6x-2y=2\qquad|-6x\\\\-2y=-6x+2\qquad|:(-2)\\\\y=3x-1

for x= 0 → y = 3(0) - 1 = 0 - 1 = -1 → (0, -1)

for x = 2 → y = 3(2) - 1 = 6 - 1 = 5 → (2, 5)

9x-3y=1\qquad|-9x\\\\-3y=-9x+1\qquad|:(-3)\\\\t=3x-\dfrac{1}{3}

for x = 0 → y = 3(0) - 1/3 = 0 - 1/3 = -1/3 → (0, -1/3)

for x = 2 → y = 3(2) - 1/3 = 6 - 1/3 = 5 2/3 → (2, 5 2/3)
