Answer:

Step-by-step explanation:
Given

--- dilation ratio
See attachment
Required
Determine length, y
First, we calculate length R'T.
Since point T is the center of dilation, then:

Substitute known values


y is between R'T and RT;
So:



Answer:
- f(x) should be reflected across the y-axis
- f(x) should be horizontally translated
Step-by-step explanation:
We imagine Jenessa's elevation plots might look like those in the attachment. The red graph would be of f(x) when preparing for the race, and the green graph would be f(x) during the race.
The green graph is not a simple reflection or translation of the red graph, but is a combination of both. Thus, the two answer choices shown above are both applicable.
Answer:
60,140
Step-by-step explanation:
alternate interior angles are congruent. and then 1 and 4 are supplementary angles which create 180
Answer:
x=67
y=36
Step-by-step explanation:
x+y=103
2y=x+5
Answer would be C because a straight line is equal to 180° so if you add up 3x° and 27° it should be equal to 180°
