Answer:
x -2y = -4
Step-by-step explanation:
The slope of the line between points C and D is ...
m = (y2 -y1)/(x2 -x1)
m = (7 -13)/(5 -2) = -6/3 = -2
The slope of the perpendicular line is the opposite reciprocal of this: -1/(-2) = 1/2. The point-slope equation of the desired line is ...
y -k = m(x -h) . . . . line with slope m through point (h, k)
y -1 = 1/2(x -(-2))
We can rearrange this to standard form.
2y -2 = x +2 . . . . . multiply by 2
-4 = x -2y . . . . . . . subtract 2y+2
x -2y = -4 . . . . . . standard form equation of the desired line
Answer:
9 tshirts
Step-by-step explanation:
Money he had for t shirts= $75
Cost of shipping= $3
Money left for t shirts= $75-$3=$72
Cost of 1 t shirt= $8
We can find the answer with two ways:
1st way: tshirts of $8=1
tshirts of $72=72/8
=$9
2nd way: Cost ($) 8 72
T shirts 1 x
8/1=72/x
by cross multiply
x=72/8
x=9

Question:
Jordan is cutting a 2 meter by 
meter piece of rectangular paper into two pieces along its diagonal. what is the area of each of the pieces?
Answer:
Area of each piece of paper is 
.
Solution:
Length of the paper = 2 m
Width of the paper = m = 
m
<em>Area of the rectangle = length × width</em>
<em>Diagonal of a rectangle divides it into two equal parts.</em>
Area of each piece = Area of the rectangle ÷ 2
Area of each piece of paper is .
