So from 20 dollars subtract this 15,24
20,00 -
15,24
---------
04,76 so this mean that Liz will get back $04,76
hope this will help you
I would pick A because if you look and plug in, you would get all your answers.
A)an=n/(n+1) n= 1,2,3,4,5
a(1) = 1/(1+1) =1/2
a(3) = 3/(3+1) = 3/4
The slope would be the same as that of the given line, and when plugging in (-3,0) into the new equation, you’ll find the y-intercept. If you could give the original given line equation I’d be happy to show you!
Answer:
![y = \frac{0}{ - 3} + b](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B0%7D%7B%20-%203%7D%20%20%2B%20b)
Step-by-step explanation:
Slope intercept formula is y=mx+b
(m) is slope
(b) is the y intercept
We'll find slope first.
slope formula is
![\frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20)
y2 and x2 are the y and x values of the second equation and y1 and x2 are the y and x values of the first equation.
So we just put the given values into our equation.
![\frac{1 - 1}{ - 3 - 0}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%20-%201%7D%7B%20-%203%20-%200%7D%20)
Simplify
![\frac{0}{ - 3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B0%7D%7B%20-%203%7D%20)
Now we put this into our y=mx+b
y=0/-3x+b
now we need the (b)
to do this we take the values of one of the coordinates (doesn't matter which) and replace the (y) and (x) in our equation with them.
![y = \frac{0}{ - 3} x + b](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B0%7D%7B%20-%203%7D%20x%20%2B%20b)
![1 = \frac{0}{ - 3} (0) + b](https://tex.z-dn.net/?f=1%20%3D%20%20%5Cfrac%7B0%7D%7B%20-%203%7D%20%280%29%20%2B%20b)
Solve
1=0+b
b=1
Put this in our formula
![y = \frac{0}{ - 3} + 1](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B0%7D%7B%20-%203%7D%20%20%2B%201)
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!
Answer:
-5
Step-by-step explanation:
5 - 2 · 3 + 4
Follow the Bodmas rule
= 5 - 6 + 4
= 5 - 10
= - 5
