What with :)
hint: what is the slope of the graph?
use the point slope formula
pick two points on the graph (0,0) and (2,9) = (x1,y1) and (x2,y2) then find m = slope = (y2-y1)/(x2-x1) = ?
nope, read carefully.
x1 = 0 y1 = 0 x2 = 2 y2 = 9 slope = (y2-y1)/(x2-x1) = ?
i dont know how to do that
what is the slope ?
90 / 20
y2 = 9 y1 = 0 y2-y1 = ?
9 / 2
good, now convert to decimal
good now p = (slope)(s)
and pick the answer that matches
old length = 8 new length = 5.5*old length = ?
good old width = 6 find the new width
remember, a scale factor of 5.5 means we multiply each dimension by 5.5
how do i find the nwe width
multiply the old width by the scale factor.....
follow the same pattern we used to find the length
new width = scale factor*old width
good so we have length = 44 and width = 33 now find the perimeter and area.
please memorize these two equations. perimeter = 2(length+width) area = length*width
now find the perimeter and area....
perimeter = 2(length+width) = ?
2 ( 8 + 5.5 )
remember we just calculated length and width...
length = ? width = ? please look back at what we wrote earlier.
8 and 5.5
read through everything we have written so far.
8 and 44
im so confused
I already told you what the length and width were. what are they?
start from the beginning and read carefully.
8 and 5.5
pay attention. length = ?
but thats what you said it was
look at the attachment.
now tell me what the length and width are.
44 and 33
good. now find the perimeter and area.
what do i calculate to find the perimeter?
use the equations I just gave you.
good now find area.
use. the. equation.
nevermind.. i got d :)
supplementary means they add up to 180. 7x + 33 = 180. solve for x.
7x + 33 + 70 = 180 solve for x
need to go, tag someone if you need help.
