Answer:
1) Point C 2) last set (-1.5,2) 3) The point will be in Quadrant IV
4) right triangle 5) (-4, -2.5)
Answer:
c
Step-by-step explanation:
A; rate of change is the same as slope, so, using the slope formula,
![m= \frac{y_{2} - y\1_{1} }{ x_{2} - x_{1} }](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7By_%7B2%7D%20-%20y%5C1_%7B1%7D%20%20%20%7D%7B%20x_%7B2%7D%20-%20x_%7B1%7D%20%7D%20)
, where
![m](https://tex.z-dn.net/?f=m)
is the slope and
![x_{1}](https://tex.z-dn.net/?f=%20x_%7B1%7D%20)
,
![x_{2}](https://tex.z-dn.net/?f=%20x_%7B2%7D%20)
,
![y_{1}](https://tex.z-dn.net/?f=%20y_%7B1%7D%20)
, and
![y_{2}](https://tex.z-dn.net/?f=%20y_%7B2%7D%20)
are the
![x](https://tex.z-dn.net/?f=x)
and
![y](https://tex.z-dn.net/?f=y)
values.
Plug in
![2](https://tex.z-dn.net/?f=2)
points for
![x](https://tex.z-dn.net/?f=x)
and
![y](https://tex.z-dn.net/?f=y)
, water level being the
![y](https://tex.z-dn.net/?f=y)
and time being the
![x](https://tex.z-dn.net/?f=x)
since we're looking for the answer in ft/hr-- you can choose any two, but from the same row.
![m= \frac{ 30-50}{4-0}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B%2030-50%7D%7B4-0%7D%20)
![m= \frac{-20}{4}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B-20%7D%7B4%7D%20)
![m= \frac{-5}{1}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B-5%7D%7B1%7D%20)
![m= -5](https://tex.z-dn.net/?f=m%3D%20-5)

Answer:
34
Step-by-step explanation:
We have to calculate non perfect square between
and ![18^{2}](https://tex.z-dn.net/?f=18%5E%7B2%7D)
So,
Let
17=n
18=n+1
Non perfect square between two number can be calculated as :
2n
2× 17=34
Therefore there are 34 non perfect numbers between
and ![18^{2}](https://tex.z-dn.net/?f=18%5E%7B2%7D)
The answer would be x is less than -6 because you’d divide both sides by -5 and then flip the inequality sign (it’s greater than but flip it to less than) then you’d have x is less than -6 :) hope this helps!
