Answer:
d= 4
Step-by-step explanation:
The DISTANCE between the two points can be found by the distance formula
d^2 = (x1-x2)^2 + (y1-y2)^2
( 1-5)^2 + (2-2)^2
= 16
d = 4
You can just LOOK and realize the two points have the same y values...so the distance is just the distance between the x coordinates 5 -1 = 4
Answer:
-5
Step-by-step explanation:
The slope of the line is found by
m = (y2-y1)/(x2-x1)
= ( -12.5 - -2.5)/( 7.3 - 5.3)
= ( -12.5 +2.5)/( 7.3 - 5.3)
= -10 /2
= -5
When comparing to thing with same rate, set up a proportion:
Inches/cost
13/.78=33/x
(13)(x)=(.78)(33) [cross multiplied]
13x=25.74 [simplified]
13/13x=25.74/13 [division property]
x=1.98
33 inches of wire will cost $1.98.
