Answer:
y = + 1x - 4y
Step-by-step explanation:
This could be the wrong way of writing it but thats the pattern ❤
Add 3 to isolate y
3.8 + 3.8 = 1.9z - 3.8 + 3.8
7.6 = 1.9z
Divide by 1.9
4 = z
you can only see values of
Ranging from $-3$ to $3$ and they're included, so domain is $[-3,3]$
and $y$ values ranging from $-2$ to $4$ but $-2$ is not included so range is $(-2,4]$
The answer is 1 mile an hour
