Answer:
C. 52.5
Step-by-step explanation:
The total from W(-20) to Z(120) is 140.
You can add up all of the numbers in the ratio, 2:3:3, to get 8
Divide 140 by 8 to get 17.5
Multiply 17.5 times the number in the ratio for each segment, so the new ratio would be 35 : 52.5 : 52.5
Since you are trying to find segment XY, which was the 2nd number in the ratio, you would get your answer as 52.5
Answer:
y+4=4(x-3)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-4)=4(x-3)
y+4=4(x-3)

Find the complete question
Zelie planned for a square pool to have a side length of 28 ft but found that it needs to be 14 ft long to fit in her backyard. She found the change of scale below.
Which is Zelie’s error?
Zelie should have divided both numbers by 14.
Zelie should have written the ratio as 28/7.
Zelie should have written the ratio as 14/8.
Zelie should have subtracted 14 from both numbers.
Original length of pool = 28ft
If he found that it need to be 14ft longer then the actual measure = 14th
given equation is;
(28 - 7)/14 - 7 = 14/7
Scale constant = original length/actual length
Scale constant = 28/14
Scale constant = 2
Hence the scale constant is 2
According to the option, Zelei should have divided both numbers by 14.
