Answer:
y = 7/8x + 1
Step-by-step explanation:
According to y = mx + b, whereas b is the y-intercept
so if b is positive, b has to be larger than 0
A non-proportional graph is a straight line that does not go through the origin so
The #1 and #4 are wrong because they are proportional
The #2 and #4 are wrong because they have negative y-intercept
Answer:
sale price is $21.75
Step-by-step explanation:
A store is having a sale where all jeans are 1/4 off the regular price.
Let x be the regular price and y be the sale price
sale price = regular price - 1/4 of regular price
![y=x-\frac{1}{4} x](https://tex.z-dn.net/?f=y%3Dx-%5Cfrac%7B1%7D%7B4%7D%20x)
![y=\frac{3}{4} x](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B3%7D%7B4%7D%20x)
equation relating the sale price to the regular price is
![y=\frac{3}{4} x](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B3%7D%7B4%7D%20x)
regular price of jeans is $29
so sale price is
![y=\frac{3}{4}(29)](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B3%7D%7B4%7D%2829%29)
y=21.75
sale price is $21.75

Answer:
2:1.
Step-by-step explanation:
The area of a red curved surface = 2πr^2.
The area of the yellow flat surface = πr^2.
This is the case for all the hemispheres.
Therefore the required ratio = 2πr^2 : πr^2
= 2:1.
