Answer:
It should be the top left graph where there is point (1,1) and (-1, -1) y = 1/x
Step-by-step explanation:
from the original graph, I see:
f(x) = 2/x because f(2) = 1 = 2/2
f(1/4)= 2/(1/4) = 2
...
so then f(2x) compresses f(x) horizontally by a factor of 2
so f(2x) = 2/(2x) = 1/x
Answer:
4(x + 2)
Step-by-step explanation:
Factor out common factors from each term. Note the factors for each number
4: 1, 2, 4
8: 1, 2, 4, 8
The largest factor for each is 4, and so divide 4 from both terms.
(4x + 8)/4 = (x + 2)
4(x + 2) is your factored expression.

Answer:
35.2 minutes
Step-by-step explanation:
Time taken=28min
Distance=7miles
Speed=7/28=0.25milesperminute
Time=distance/speed
Time=8.8/0.25
=35.2 minutes
Answer:
B) 6cm x 3cm
Step-by-step explanation:
Volume of a rectangular box is length * width * height
In our case that means
(length * width, also known as base) * 5 = 80
this means the base has to be 16 cm^2
This means the only option that doesn't work is B, which would be 18 cm^2
