Pls see answer below.
Step-by-step explanation:
In this case, our slope is -8. This means that every hour, the storm is getting closer to the town by 8 miles per hour.
Our y-intercept is 200, which means that its' initial position is 200 miles away from the town.
Hope this helped.
30=12m
you divide both sides by 12
so 30/12 is 2.5
Answer:
9
Step-by-step explanation:
so you write the expression 2.75+1.25x= ?
If we subsitute the X for 5(miles) the we'll have the expression 2.75+1.25(5)= ?
and if you simplify that you will get 9.
