Answer:
72/107
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
= (-1 -71)/(-100-7)
= -72/-107
= 72/107
Answer:
Given the details of the study carried
out on Hospitals to study the possibility that carpers might be more likely to harbor
germs, in which air from rooms with carpet and those without carpet was pumped over a
dish of agar, and the number of bacteria colonies were counted after incubating
the dish for a fixed period of time. The response in this study is number of bacteria colonies in a dish.
Answer:
-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-2-4)/(-7-(-9))
m=-6/(-7+9)
m=-6/2
m=-3
Hey there!
Apply fraction cross multiply: if a/b = c/d , then a *d = b*c
2 ( 5x - 2 ) = ( 2x + 4 ) * 4
expand : 2 (5x-2 ) => 2*5x - 2*2 => 10x - 4
expand : ( 2x +4 ) * 4 => 2x * 4 + 4*4 => 8x + 16
10x - 4 = 8x+16
add 4 to both sides:
10x-4+4 = 8x+16+4
simplify :
10x = 8x + 20
subtract 8x from both sides:
10x -8x = 8x+20-8x
simplify:
2x = 20
Therefore:
x = 20 / 2
x = 10
Hope that helps!
