Answer:
x-9=17
Step-by-step explanation:
x=eggs in the fridge
f(3) = 1
substitute x = 3 into f(x)
f(3) = (2 × 3) - 5 = 6 - 5 = 1
Step-by-step explanation:
![given \: - 5n = 4m](https://tex.z-dn.net/?f=given%20%5C%3A%20%20-%205n%20%3D%204m)
making m the subject first by dividing through by 4
![\frac{ - 5}{n} = \frac{4m}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%205%7D%7Bn%7D%20%20%3D%20%20%5Cfrac%7B4m%7D%7B4%7D%20)
![m = \frac{ - 5n}{4}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B%20-%205n%7D%7B4%7D%20)
from the question, given n = -1 ,0 ,1
so when n= -1
![m = \frac{ - 5( - 1)}{4}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B%20-%205%28%20-%201%29%7D%7B4%7D%20)
![m = \frac{5}{4}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B5%7D%7B4%7D%20)
when n=0
![m = \frac{ - 5(0)}{4}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B%20-%205%280%29%7D%7B4%7D%20)
![m = \frac{0}{4}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B0%7D%7B4%7D%20)
![m = 0](https://tex.z-dn.net/?f=m%20%3D%200)
when n=1
![m = \frac{ - 5(1)}{4}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B%20-%205%281%29%7D%7B4%7D%20)
![m = \frac{ - 5}{4}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B%20-%205%7D%7B4%7D%20)
Answer:
Step-by-step explanation:
i cant draw a number line but we know that integers above 1 are positive. So 1,2,3,4, and 5 are positive and marked
