Step-by-step explanation:
the markup is 700 so add that to the 500, then sales tax adds 96
Answer - D.
you basically find the equation of the line first and eliminate the wrong answers...
Strategy: before u do any of this, label your coordinates as (X1,Y1) and (X2,Y2) and u can choose any of ur points to be as x1 or x2 or y1 or y1...
basically, I'll choose (6,7) as (x1,y1) and (2,-1) as (x2,y2). SO,
First you have to find the gradient (m) of the line.
you do this by using the formula m = Y2-Y1 / X2-X1 (where '/' is division sign) ....
Put the numbers in their respective places and your gradient will be 2x. we put the x after our number to represent it as a gradient as the straight line formula is y = mx+c and you've found the m.
NOW.
use the formula Y-Y1=m(x-x1) to find the equation of the line.Again u can use any Y1 and X1 here but remember your m is 2
replace the digits and solve...Hopefully you'll get sth like this if you use the points (6,7):
Y-7 = 2(x-6) ....
y=2x-12+7...
Y=2x-5! <<<< this is your straight line equation!
Now all u gotta do is rearrange all your options into y = mx+c.
D. is incorrect as it gives us y=2x+5 and not y = 2x-5 unlike the others
Hope you get it!
Hello from MrBillDoesMath!
Answer:
9, 11
Discussion:
From the attachment,
P = w + l + w + l
= 2w + 2l => as l = w + 2
= 2w + 2( w+2)
= 4w + 4
= 40 (given value)
4w + 4= 40 => subtract 4 from both sides
4w = 40 -4 = 36 => divide both sides by 4
w = 36/4 = 9
This implies that l = w+2 = 9 + 2 = 11
Thank you,
