Answer:

-3.8=n

Step-by-step explanation:

My goal is to get n all by itself, but its multiplied by 6. If I do the inverse operation (which is division) on both sides I will get -22.8/6=n. Now I can just simply combine the like terms and finalize my answer. 6 * 3=18 but -22.8 is a decimal number so my answer will range from around 3.5-3.9. if I divide -22.8/6 I get -3.8. My final answer is n=-3.8

Consider the graph of the line y = .5x- 4 and the point
Katena32 [7]

Answer:

slope of parallel line and perpendicular line are 5 and -1/5 espectively

equation of parallel and perpendicular line are y = 5x + 22 y= \frac{-1}{5} x+\frac{6}{5} respectively

Step-by-step explanation:

y = 5x - 4 is in the form

y = mx + c

where m is the slope of the line and c is the y intercept of thr line

therefore slope of the line = 5 and y intercept = -4

when an another line is parallel to the given line then the slope of both the lines are equal

therefore the slope the parallel line = 5

equation of a line passing through a given point (x_{1} ,y_{1}) with slope m is given by y-y_{1} = m(x-x_{1} )

given (x_{1} ,y_{1})= (-4,2)

therefore equation of line y-2 = 5(x+4)

therefore y = 2+ 5x+20

y = 5x + 22is the eqaution of required line.

when two lines are perpendiculer then

m_{1} m_{2}=-1

where m_{1} and m_{2} are slope of the lines therefore

m×5=-1

therefore m= \frac{-1}{5}

therefore eqaution of line passing through (-4,2) and with slope m= \frac{-1}{5} is given by y - 2= \frac{-1}{5} (x+4)

y= \frac{-1}{5} x+\frac{6}{5}

Solve for X plz plz plz plz
Sliva [168]

Answer:

Step-by-step explanation:

B/c they are similar triangles we can set the sides ratio's equal to each other again

7x + 6 / 56  = 78 /91

does it kind of makes sense why I'm able to set those two ratio's equal?

it's the tough part of these problems... understanding why that works

the rest is just algebra.. My calc II professor always told us our algebra sucks. :D he was funny,

anyway, use your mad algebra skilz on the above equation

7x + 6 = 56(78/91)

7x + 6 = 4368 / 91

7x + 6 = 48

7x = 48 - 6

7x = 42

x = 6
