Answer:
b
Step-by-step explanation:
In general
Given
y = f(x) then y = f(Cx) is a horizontal stretch/ compression in the x- direction
• If C > 1 then compression
• If 0 < C < 1 then stretch
Consider corresponding points on the 2 graphs
(2, 2 ) → (4, 2 )
(4, - 2 ) → (8, - 2 )
Indicating a stretch in the x- direction.
y = f(
) with C =
, that is 0 < C < 1
stretches the graph in the x- direction by a factor of 2
Thus
y = f(
) → b
Answer:
220 miles
Step-by-step explanation:
65 miles per hour for 2 hours — 65+ 65 = 130
60 miles per hour for 1.5 hours — 60 (for the 1 hour) + 30 (for the half hour) = 90
130 + 90 = 220
Answer:
Step-by-step explanation:
I can’t see the attached paper
Answer:
x and y do not have a proportional relationship. The constant would be 1.7
Step-by-step explanation:
The reason for this is because as the miles increase they are not following a straight pattern. While 14+14=28 and 28+14=42, 42+14 doesn't equal 70. Even if you think about it in a sense of multiplication, while 14x2=28, 28x2 does not equal 42. What should be done is that the opposite factor of each number should be added together and divided by 3. So 28/14=2, 42/28=1.5, and 70/42=1.6. Then you should take the numbers 2, 1.5, and 1.6, add them together and divide by 3. The answer that you should recieve is 1.7.
Hope that helped.
