Answer:

Answer:

Step-by-step explanation:

Carrying out the indicated multiplication, we get

3y - 6 + 6x + 6 - 2 = 0.

Combining like terms, we get 3y = -6x + 2.

Solving for y: y = -2x + 2/3.

The slope is -2 and the y-inercept is 2/3.

I don't need an answer, just an explanation of how to do it. 1-(-3)

Step-by-step explanation:

When you are subtracting a negative number from a positive number, the negative - sign will always turn into a positive + sign.

So in this case, you would cancel out the negative - signs and put in a positive + sign: 1-(-3) --> 1+3

How do you do this problem and please show the work? 3/4 (4-x)

(3/4*4)+(3/4*-x)= (3)+(-3/4x) = -3/4x+ 3

A pharmacist has 18% bleach solution. How much of this solution and how much water must be mixed together to make 10 liters of a 12% solution?

X = the amount of water to add

10 - x = amount of 18% bleach to add

.18(10-x)= .12 x 10

1.8 -.18x =1.2

-.18x = -.6

x = 3 1/3 liters water

therefore 6 2/3 liters bleach

10 - x = amount of 18% bleach to add

.18(10-x)= .12 x 10

1.8 -.18x =1.2

-.18x = -.6

x = 3 1/3 liters water

therefore 6 2/3 liters bleach
