Answer:
The coordinates of H’ is (-1,-6)
Step-by-step explanation:
Here, we want go get clockwise rotation about the origin
mathematically, if we had this kind of rotation, it would be that
(x,y) will turn to (y,-x)
So we have it that (6,-1 becomes)
(-1,-6)
Answer:
f(x) = x*3/4 + 42.5
Step-by-step explanation:
The original difference between the pair is 70 - 30 = 40
The new difference between the pair is 95 - 65 = 30
Since the differences are not the same, Mrs Bailey must first perform a (slope) multiplication by a factor of 30/40 or 3/4
Then 30 * 3/4 = 22.5
Then she can shift the scores up by 65 - 22.5 = 42.5 in order to get the range from 65 to 95
Therefore, f(x) = x*3/4 + 42.5. We can test that
f(30) = 30*3/4 + 42.5 = 65
f(70) = 70*3/4 + 42.5 = 95
Answer:
The answer is B
Step-by-step explanation:
The range is the difference between the greatest and least, so the difference between the most time spent surfing the internet and the least time surfing the internet would be the answer.
