Answer:

0.25p+20

Step-by-step explanation:

Since there is a set up fee of $20 then you would have to add it to the value of what 0.25p will be. Since p represents every square foot of the walls and you would multiply p by 0.25 every square foot is $0.25 then 0.25p+20 would accurately represent the problem

What is the result of subtracting the second equation from the first? \begin{aligned} x-3y &= 6 \\\\ -8x-y &= 6 \end{ali
Mila [183]

Answer:

Therefore the required result is 9x-2y =0.

Step-by-step explanation:

Given equation are

x-3y =6.....(1)

-8x-y=6 .....(2)

Subtracting equation (2) from (1)

 x  -  3y = 6

-8x  -  y=  6

+     +      -                 [ The sign of equation (2)  will be change in case of          

_________               subtraction and in case of plus the signs remains same ]

(x+8x)-3y+y=6-6   [ adding the like terms]

⇒9x-2y =0

Therefore the required result is 9x-2y =0.

Find an equation for the line with slope m through the point (a,c).
lidiya [134]
If you want the answer in point slope form then,

y-y1 = m(x-x1)
y-c = m(x-a)

---------------------------------------

If you want the answer in slope intercept form, then solve for y

y-c = m(x-a)
y-c = mx-ma
y-c+c = mx-ma+c
y = mx-ma+c
y = mx+c-ma
y = mx+(c-ma)

For this answer in slope intercept form the slope is m and the y intercept is c-ma

---------------------------------------

If you want the answer in standard form, then get the variable terms to the left side. Have the constant terms on the right side.

y = mx+c-ma
y-mx = mx+c-ma-mx
-mx+y = c-ma

Optionally you can multiply both sides by -1 to get mx-y = -c+ma but it will depend on your book if this step is carried out or not.
