Two lines are represented by the equations -1/2y=6x+10 and y=mx for which value of m will the lines be parallel
hjlf

Answer:

-12

Step-by-step explanation:

So to start we need to know what makes a line parallel. In an equation we know that for lines to be parallel they must have the same slope(m).

Then, we  need to know the slope-intercept form of an equation. The slope intercept form is y=mx+b where m is the slope of the line and b is the y-intercept. In this problem where can see the second equation is already in this form.

Now that we know we need to find the slope, and we know that the second equation is in slope-intercept form we're going to convert the fist equation into the correct form.

To do this, we know we need to make sure y is the only thing on the left side of the equal sign. Currently, on the left side of the equal sign we have -\frac{1}{2} y so we have to divide both sides by -\frac{1}{2} to get y=-12x -20

Now that we have it converted to slope-intercept form, we are going to look for what represents the slope or m in the equation. In this case the slope would be -12, so any line with a slope of -12 will be parallel.

Margret is inviting 3 friends to a party. If each friend will get 8 cookies and each box has 6 cookies, how many boxes does Marg
Alisiya [41]

Answer:

Margret need to get 4 boxes of cookies.

Step-by-step explanation:

Total friends = 3

Cookies each friend will get = 8

Each box has cookies = 6 cookies

How many boxes does Margret need to get?

Total cookies will be= Total friends x Cookies each friend will get

Total cookies will be= 3 x 8 = 24

If one box has 6 cookies and we need total 24 cookies so, divide 24 by 6 to get number of boxes

Number of boxes = Total cookies/ number of cookies in one box

Number of boxes = 24/6

Number of boxes  = 4

So, Margret need to get 4 boxes of cookies.
