Check whether it is possible to have a triangle with the given side lengths for example 7,9,13 then add any two sides and see if it is greater than the other side. Example the sum of 7 and 9 is 16 and 16 is greater than 13
The slope-intercept form:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
m - slope (a rate of change)
b - y-intercept
We have the slope ![m=-3\to y=-3x+b](https://tex.z-dn.net/?f=m%3D-3%5Cto%20y%3D-3x%2Bb)
and point (3, -5). Substitute:
![-5=-3(3)+b](https://tex.z-dn.net/?f=-5%3D-3%283%29%2Bb)
<em>add 9 to both sides</em>
![4=b\to b=4](https://tex.z-dn.net/?f=4%3Db%5Cto%20b%3D4)
Answer: ![y=-3x+4](https://tex.z-dn.net/?f=y%3D-3x%2B4)
I think it’s 48 but are those the only answer choices???
Definition: as substances that are made of only one type of atom or molecule.
Examples: tin, sulfur, diamond, water, pure sugar (sucrose), table salt (sodium chloride) and baking soda (sodium bicarbonate).
hope this helps!
