Eight more than the product of four and a number is twice the sum of the number and six. Write an equation that can be used to s

masha68 [24]

4n+8=2(n+6)
Now isolate the n on one side of the equation:
4n+8=2n+12(distribution of the 2)
4n=2n+4(combine like terms)
2n=4(combine like variables)
N=2(isolate the n)

The answer is 2
Good luck!

The point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is y – 4 = (x – 8). What is the slop

Masteriza [31]

[ y - 4 = x - 8 ] is not the equation of the line that goes through
those two points. The first point (8, 4) is on the graph of that
equation, but the second point (0, 2) is not.

The slope/intercept equation of the line that passes through
both points (8, 4) and (0, 2) is

y = 1/4 x + 2 .

The slope/intercept form of [ y - 4 = x - 8 ] is

y = x - 4 .

PLEASE HELP IM STUCK PLS

QveST [7]

Answer:

<u>The slope is -3.</u>

Step-by-step explanation:

The slope is the Rise/Run between the two points. The change in y for every change in x. Take the two points and calculate the:

RISE = (-6 - 3) = -9

RUN = (8 - 5) = 3

Rise/Run, or slope, is = -9/3 or -3

I graphed a line with slope of -3 and then added 18 to force the line to intersect the two given points.

What is Y-3x=-2 and Y+x=-6

love history [14]

Rearranging the first equation gives:

$y=3x-2$

Substituting this into the other equation gives:

$y+x=-6
\\(3x-2)+x=-6
\\4x-2=-6
\\4x=-4 \\x=-1$

If x=-1:

$y+(-1)=-6
\\y=-5$

So x=-1, y=-5
