Answer: (-2,3)

Step-by-step explanation:

-3x + 4y = 18

6x + 2y= -6        we have to eliminate one of the variables so you will have ot

2(-3x + 4y) = 18(2)     multiply the first equation by 2.  

-6x + 8y = 36

6x +  2y = -6       now we could eliminate the x terms by adding them and

0  +   10y= 30   remember that is a new equation.  

       y=  3

Now we know that the y solution is 3 so we will put it into one of the equations and solve for x.

-6x + 8(3)=36

-6x + 24

-24   -24

-6x =  12

x= -2

James works in a flower shop. He will put 60 tulips in vases for a wedding. He must use the same number of tulips in each vase.
Lina20 [59]

Answer: a. 1, 3, 5, 15

Step-by-step explanation:

If he needs to put an equal number of tulips in each vase he uses, the number of vases will have to be multiples of 15.

The multiples of 15 are;

1, 3, 5, and 15.

James can therefore put;

  • 1 tulip in 15 vases
  • 3 tulips in 5 vases
  • 5 tulips in 3 vases
  • 15 tulips in 1 vase

How many solutions does this system of equations have? y=3x+1 y=3x+7
frutty [35]

Answer:

The following system of equation has no solution.

Step-by-step explanation:

since both of them are equal to y, set them equal to each other:

3x+1=3x+7

if you subtract both sides by 3x, you get 1=7. That is a contradiction, so this has no solutions.
