An inequality for this speed sign would need to be one where x is less than or equal to 25mph. We don't have to go exactly 25mph, but it's okay if we do go exactly 25mph. We can also go less than 25mph without getting a ticket.
An inequality equation would look like this:
x < 25
***should be less than or equal sign but I don't have one on my keyboard
Hope this helped!! :)
You started with $452. Hope I helped and good luck(:
Let the number of free throws be x and that of point shots be y
x+y=25
⇒x=25-y...i
also:
x+2y=46...ii
substituting i in ii we get:
(25-y)+2y=46
solving for y we get:
y=21
hence
x=25-21=4
thus the number of free shots was 4 and that of point shots was 21
Answer:
2x^2 - 10x - 8.
Step-by-step explanation:
f(x) = 2(x - 1)(x + 4)
= 2(x^2 - x - 4x - 4)
= 2(x^2 - 5x - 4)
= 2x^2 - 10x - 8.
The formula to solve:
![10 = 16](https://tex.z-dn.net/?f=10%20%3D%2016%20)
(10 being the percent)
![16*2= 32](https://tex.z-dn.net/?f=16%2A2%3D%2032)
![160-32= 128](https://tex.z-dn.net/?f=160-32%3D%20128)
Therefore it had a 180% decrease.
