Let
<span>A (4,8) and B (3,5)

</span>step 1
find the slope m
m=(y2-y1)/(x2-x1)---------> m=(5-8)/(3-4)----> m=-3/-1----> m=3

step 2
with m=3 and point B (3,5) find the equation of the line
y-y1=m*(x-x1)-----> y-5=3*(x-3)----> y-5=3x-9----> 3x-y=4

the answer is
<span>the equation in the form Ax+By=C is
</span> 3x-y=4

see the attached figure

UW= 2 and UX=y. Write an expression for WX
Eddi Din [679]
Divide each term by U and simplify. X=y/U and W=2/U. Next, solve the equation for y. Simplify the left side then cancel the common factor of U. 1/1*y/1=y

W=2/U. Multiply 1/1*y/1=y/1 so, y/1=y and W=2/U. Next, divide y/y to get 1 now y=y, still W=2/U. Now, move all terms containing y to the left side.  Since, Y contains the variable to solve for, move it to the left side of the equation by subtracting y from both sides. Now, y-y=0 still W=2/U.  Next, subtract y from y to get zero and still W=2/U.  Subtract y from y to get zero or 0=0 and W=2/U is your expression since 0=0.


Next: UW=m and WX=y+14  write expression for UX

First, divide each term by W and simplify. U=m/W, WX=y+14. Next, solve the equation for Y. Move y from the right side of the equation to the left side. Still, U=m/W and y=-14+WX.  We must reorder -14 and WX. U=m/w and y=WX-14.
Replace the variable U with m/W in the expression to (m/W)X. Next, simplify (m/W)X. Now, write X and a fraction with denominator 1. Looks like this
fractions are side by side m/W X/1 . Multiply, m/W and X/1 to get mX/W.
mX/W is your final expression for UW=m and WX=y+14 expression for UX.

S=L−rL<br><br> solve for r<br><br> Please solve this fast for much points.
podryga [215]
Subtract L from both sides. 
the expression now becomes,
<span>S−L=−rL</span>
2)Divide by L on both sides.
<span><span><span>S−L</span>L</span>=−r</span>
3)Multiply with a negative sign on both sides in the final step to obtain the expression in terms of r      so the answer is<span> #(L-S)/L = r#</span>

On average during the summer, a 30,000 cubic foot house costs $7 per day to cool, while a 25,000 cubic foot house costs $6.50 pe
Ber [7]

The house with 30000 cubic foot costs less to cool per cubic foot than the house with 25000 cubic foot.

Step-by-step explanation:

The cost of cooling 30000 cubic foot house = $7

Cost per cubic foot = 7/30000

=$0.00023

The cost of cooling 25000 cubic foot house= $6.50

Cost per cubic foot=6.50/25000

= $0.00026

The house with 30000 cubic foot costs less to cool per cubic foot than the house with 25000 cubic foot.
