Answer:
y=-2x+20
Step-by-step explanation
The slope is determined with the "spent $2 each day" which translates to -2x and the y intercept should be how much money he started with($20). It looks like Nolan divided 20/2 to get 10, which would be how many days until he would have no money. Hope this helps!
Answer:
y=-2x-3
the line is going downwards which makes the slop a negative value
Step-by-step explanation:
The greatest common factor is 6
36: 1, 2, 3, 4, 6, 9, 12, 18, 36
42: 1, 2, 3, 6, 7, 14, 21, 42

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.
Step-by-step explanation:
The GCF of 28 and 80 is 4.
<u>Distribute 4 for 28 and 80, then solve:</u>
