Answer:

y=-2x+6

Step-by-step explanation:

You want to to turn the given equation 4x+2y=12 into y=mx+b

** m is the slope and b is the y-intercept

The first step is to isolate y. First subtract 4x from both sides:

4x+2y=12

2y=-4x+12

Now you have y mostly isolated, all you have to do is divide both sides by 2:

2y=-4x+12

y=-4/2x +12/2

y=-2x +6

Now you have your equation, plug in values for x to find y to fill in the table:

ex: y=-2(2)+6

y= -4+6

y= 2

** an order pair ex.: (2,2)

Answer:

(1,4), (2,2) (3,0)

Step-by-step explanation:

adjust the equation so that the y is isolated so subtract 4 x

2y=4x +12

Every number is divisible by 2 so you can further isolate the y

y=-2x+6

Plug your x coordinates into the equation so get the y coordinates

Mike is buying eight tickets for a concert. A package of five tickets costs $74.45. Individual tickets cost $17.25 each. What is

svetlana [45]

Answer:

$126.20

Step-by-step explanation:

Given:

Mike is buying eight tickets for a concert.

A package of five tickets costs $74.45.

Individual tickets cost $17.25 each.

To Find:

What is the least amount that Mike can pay for eight tickets? Be sure to include a decimal point in your answer.

Solve:

Since we know that:

A package of five tickets costs $74.45.

Individual tickets cost $17.25 each.

Hence we know that 5 + 3 = 8

Thus,

$74.45 = 5 tickets

Now for the 3 tickets we can do individual tickets which cost $17.25

$17.25 × 3 = 51.75

Then we add both together:

51.75 + 74.45 = $126.20

Answer:

The answer is letter A.

Step-by-step explanation:

The amount that each company charges per hour on the pool is known, however the amount of hours they will be working is not, and is needed to distinguish which company is cheaper. Therefore, the number of hours is substitued by x and it is right next to the amount they charge for each hour. To find what each company charges, you must sum up what they charge and what they charge per hour, times the hours they will have to work on it( which is unknown and by x).
