Answer:
length = 20 ft, width = 11 ft
Step-by-step explanation:
let w be width, then length = w + 9
The opposite sides of a rectangle are equal , then
2w + 2(w + 9) = 62
2w + 2w + 18 = 62
4w + 18 = 62 ( subtract 18 from both sides )
4w = 44 ( divide both sides by 4 )
w = 11
and w + 9 = 11 + 9 = 20
then width = 11 ft and length = 20 ft
If the school spent $1,137.50 and wants to make a $1500 profit, then they need to make $2637.50 to earn back what they spent and make a profit. So, if you divide $2637.50 by 350, the number of books they purchased, you get the amount each book would have to cost to make this much money. The lowest price they could sell them for is $7.54.
I think it would be -9.64
First you have to put it into point-slope form before you can write it in slope-intercept form which is y-y1=m(x-x1)
Y-1=2(x-1)
Distribute the 2 to the x and -1
Y-1=2x-2
Move it all to one side
Y=2x-1
Therefore, the solution is: x = 4, y=1.
