Answer: The solution is   (0,2)

Step-by-step explanation:

2x +3y = 6      We will solve the  equations using the elimination method

-5x +2y= 4     but first we need to eliminate one of the variables and we will multiply the first equation by 5 and multiply the second equation by 2 to eliminate the x variable.

5(2x + 3y) =6(5)     new equation  :  10x  +15y = 30

2(-5x + 2y) = 4(2)   new equation   ;   -10x +4y =8    

Now we have to new equations so we will eliminate the x term by adding

10x  +15y = 30

 -10x +4y =8    

       19y = 38  divide both sides by 19.

  y= 2     Now using the solution for y plot it  into one of the new equations and solve for x

10x + 15(2) = 30

10x  + 30  =  30

        -30       -30

10x = 0

x= 0

What is the answer for 4x + 2y = 12
sesenic [268]

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

Can someone please help me with this? It would be greatly appreciated:) thanks

Answer:

d < 1

Step-by-step explanation:

First, we have to get d on the same side of the equation. So we will subtract d from both sides and the equation will be  12d-d < + 11. We could also write this problem as d(12-1) < 11, which when simplified would be d(11) < 11. Next, divide both sides by 11 and you get d< 1.   Hope this helps and have a great day!!:D

A department store is having a 15% off sale on all winter coats. You purchase a winter coat for $275. The department store is lo
sergeinik [125]

$275*.15(15%)=41.25 (this is the amount of the discount)

$275-$41.25=$233.75 (cost of jacket after discount)

$233.75* .0725=$16.946(round to $16.95, this is the amount of the sales tax).

If you want to know the total cost after tax just add $16.95 to the discounted price of $233.75. The price you pay for the jacket is $250.70.
