Answer:
we have
(x,y). rotation through 90° anti-
clockwise about the origin(-y,x)
point (−8, 4) when rotated through 90° anti-
clockwise about the origin(-4,-8)
<u>Option.i. (−4, −8)</u>
<u>Answer:</u>
Michelle purchased 25 audio files in January. The percent increase is 60%
<u>Solution:
</u>
Given Data:
Michelle purchases = 25 audio files in January
Again purchased = 40 audio files in February
We need to find the percent increase for the given data.
Step 1:
Use the formula for percent change
,

Step 2:
First we find the amount of change from the question.
Amount of change = 40 – 25
By subtracting, we get 15.
Step 3:
substitute the values in formula we get,
Formula percent change =
= 0.6
Percent = 0.6
100 = 60 %.
Result:
Michelle purchased 25 audio files in January. And In February she purchased 40 audio files. Hence the percent increase is 60%.
Answer:
Step-by-step explanation:
(7,2) , (0,0)
slope = (y2 - y1) / (x2 - x1) = (0 - 2) / (0 - 7) = -2/-7 = 2/7
y = mx + b
slope(m) = 2/7
(0,0)...x = 0 and y = 0
now sub
0 = 2/7(0) + b
0 = b
ur equation is : y = 2/7x + 0.....same as y = 2/7x <====
Answer:
A y+5 > -2
Step-by-step explanation:
We have an open circle at -7. An open circle means greater than
y >-7
We want to add 5 to each side since all of our inequalities have +5 on the left
y+5 > -7+5
y+5 > -2
