6x + 5y = 4<br> - 6x + y = 20
Masja [62]

Answer:

x = -8/3

y = 4

Step-by-step explanation:

I assume you want to solve for x and y.

The best way to do this with the two formulas given is elimination. This means add the two equations together.

6x + 5y = 4

-6x + y = 20

The 6 x and -6x will cancel each other. By adding the like terms of the two together you will come out with

6y = 24

Now solve for y by dividing both sides by the 6.

y = 24/6 = 4

Now that we have y, you can plug it into one of the equations and solve for x.

Let's use -6x + y =20.

So plug in the 4 for y to get -6x + 4 = 20

Subtract the 4 from both sides then solve for y by dividing both sides by the -6.

-6x = 16

x = -16/6

You can reduce that down so that x = -8/3.

Lapatulllka [165]

Answer:

M =  2620 + 16d

M = total money paid or earned

d = # of days

Step-by-step explanation:

15  food

23 game

Total Money  =  M = 15 * 75  + 9 d   +  23* 65  + 7d

M = 15 * 75  + 9 d   +  23* 65  + 7d

M  =  1125  + 1495 + 16d

M =  2620 + 16d

Does this set of ordered pairs represent a function?
skelet666 [1.2K]
Yes...because every x value corresponds to exactly one y value

a function will not have any repeating x values...it can have repeating y values, just not the x ones. So if all the x values are different, then it is a function
