Answer:
40/9
Step-by-step explanation:
You can write 1 4/5 as an improper fraction which is
. 8÷
is the same as
which is ![\frac{40}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B40%7D%7B9%7D)
Answer:
Option B.
The first step is find the slope using the formula ![m=\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
The rate of change is m=3
Step-by-step explanation:
we know that
The equation of a line in slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
m is the slope
is the y-intercept
so
The firs step is determine the slope of the linear equation
The formula to calculate the slope between two points is equal to
![m=\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
we have
(-3,1) and (-4,-2)
substitute the given values in the formula
![m=\frac{-2-1}{-4+3}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-2-1%7D%7B-4%2B3%7D)
![m=\frac{-3}{-1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-3%7D%7B-1%7D)
![m=3](https://tex.z-dn.net/?f=m%3D3)
Remember that
In a linear equation the rate of change is a constant and is equal to the slope of the line
so
The rate of change is 3
Option 2:
is the correct answer
Step-by-step explanation:
Given fraction is:
![\frac{2x-24}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B2x-24%7D%7B8%7D)
In order to simplify, we can see that the function is already in compact form
So,
We can simplify the given fraction.
We can see that the numerator can be further simplified
![\frac{2(x-12)}{8}\\=\frac{x-12}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B2%28x-12%29%7D%7B8%7D%5C%5C%3D%5Cfrac%7Bx-12%7D%7B4%7D)
Hence,
Option 2:
is the correct answer

Answer:
One mole of lithium (Li) is equal to 6.022 X 1023 atoms of lithium.
Answer:
180 dollars
Step-by-step explanation:
if it was discounted by 30 percent, that means 126 is 70 percent of the orin=inal price. If you divide 126 by 70, you get 1.8 is the money worth 1 percent. Multiply 1.8 by 100 to get the original price, and you end up with 180 dollars.
