Answer:
420 minutes
Step-by-step explanation:
1 hour = 60 minutes
7 * 1 hour = 7 * 60 minutes
7 hours = 420 minutes
Three possible answers are:
y = 2x-1
y = 5x-1
y = -3x-1
All of them have the same y intercept of -1. The slopes are the only thing that differ.
Any linear equation can be written in the form y = mx+b where
m = slope
b = y intercept
Answer:
The value of y = 11/2
Step-by-step explanation:
As the work is completed up to the point
![\frac{11}{5}=\frac{2}{5}y](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B5%7D%3D%5Cfrac%7B2%7D%7B5%7Dy)
Now completing the remaining work
![\frac{11}{5}=\frac{2}{5}y](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B5%7D%3D%5Cfrac%7B2%7D%7B5%7Dy)
Dividing both sides by 2/5
∵ ![\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{\frac{b}{c}}=\frac{a\cdot \:c}{b}](https://tex.z-dn.net/?f=%5Cmathrm%7BApply%5C%3Athe%5C%3Afraction%5C%3Arule%7D%3A%5Cquad%20%5Cfrac%7Ba%7D%7B%5Cfrac%7Bb%7D%7Bc%7D%7D%3D%5Cfrac%7Ba%5Ccdot%20%5C%3Ac%7D%7Bb%7D)
∵ ![\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}](https://tex.z-dn.net/?f=%5Cmathrm%7BMultiply%5C%3Afractions%7D%3A%5Cquad%20%5Cfrac%7Ba%7D%7Bb%7D%5Ccdot%20%5Cfrac%7Bc%7D%7Bd%7D%3D%5Cfrac%7Ba%5C%3A%5Ccdot%20%5C%3Ac%7D%7Bb%5C%3A%5Ccdot%20%5C%3Ad%7D)
∵ ![\mathrm{Cancel\:the\:common\:factor:}\:2](https://tex.z-dn.net/?f=%5Cmathrm%7BCancel%5C%3Athe%5C%3Acommon%5C%3Afactor%3A%7D%5C%3A2)
∵ ![\mathrm{Cancel\:the\:common\:factor:}\:5](https://tex.z-dn.net/?f=%5Cmathrm%7BCancel%5C%3Athe%5C%3Acommon%5C%3Afactor%3A%7D%5C%3A5)
∵

Therefore, the value of y = 11/2
Answer:
D
Step-by-step explanation:
d is not a function because if you do the vertical test for d
the line goes through it twice and if it goes through it twice it means it's not a function, D did not pass the vertical test
I put two pictures so you can see the difference. it shows you if it passed the vertical tesft or not. if you do not know abt the vertical test, you will learn abt it soon. a vertical test is very helpful to find out if it is a function or not. THE VERTICAL TEST CAN ONLY BE USED ON GRAPHS nothing more. I hope I helped.
