He was slower the second time because 1/10 > 1/12
Answer:20%
Step-by-step explanation:
You add 72 plus 18 and get 100 then you find what 100 divided by 5 is.
To find the slope of the line:
(y2-y1)/(x2-x1)
(14-5)/(4-1)=(9)/(3)=3
Only one of your 4 possible answers has 3 as a slope. However, plugging in each point into the y=mx+b equation, the y-intercept consistently comes out as 2..
y=mx+b
14=3(4)+b b=2
5=3(1)+b b=2
y=3x+2
If there is a consistent, positive slope (from your question, this does not seem to have a quadratic as an option), 3x+5 is not even a viable solution because x=1 when the y-value is 5 (and thus no other x value {0} could have a y-value of 5). It seems as though you have a typo on your hands. Hopefully this helps?
Answer:
0
Step-by-step explanation:
Slope = 
(-2,-5) = (x1,y1)
(18,-5) = (x2,y2)
Slope = 
= 
= 0
Answer:
C
Step-by-step explanation:
A 3x =\ x^3
B 12x - 10 =\ 14x-10
C 12x + 16x = 12x +16x
