Perpendicular slope= 1/2

y=1/2x+b

3=1/2(4)+b

3=2+b

b=1

the new equation is y=1/2x+1

If m + n = 12 and n = 5, what is m-n?don't know the answer ​
vladimir1956 [14]

We need to find m first.

m+n=12, n=5 (plug in n as 5)

m+5=12   (subtract both sides by 5)

m=7

m-n: we know that m is 7 and n is 5

7-5=2

The final answer is 2.

Which is a better buy?
pav-90 [236]

Answer: I would say to go with "2-cup carton of pineapple juice for $1.04"

Step-by-step explanation:

If you want more pineapple juice for a cheaper price go with 2-cup carton for $1.04 The reason I say this is because 2 quarts equal 8 cups, so if you multiply the 2 cups and price by 4 you get 8-cups= $4.16 which is cheaper.

How much should each person receive?
seraphim [82]
Add up the 13+12 to get 25 then divide 500,000 by 25 to get 2,000. Then multiply it by 13 to get 26000 and by 12 to get 24000. Subtract 26000 minus 24000 to get 2000. 2000 is your answer.

Match each formula on the left with an equivalent formula on the right.
ozzi

The formulas and the equivalent formulas are

W = X - Y                                    X = W +Y

W = X/Z - Y                                 X = Z(W + Y)

W = (X - Y)/Z                               X = WZ+Y

W = XY                                       X =W/Y

<h3>How to match the formulas?</h3>

To do this, we simply make X the subject of the formula in expressions on the left.

So, we have:

W = X - Y

This gives

X = W + Y

W = X/Z - Y

This gives

X/Z = W + Y

X = Z(W + Y)

W = (X - Y)/Z

This gives

X - Y = WZ

X = WZ + Y

W = XY

This gives

X =W/Y
