(3,0) and (0,9)
Slope= (9-0)/(0-3)= -3
Line equals Y= -3x+9
We get 65 miles away from Pittsburgh each hour, but we also started 80 miles away. Thus, our formula for dd is dd = 65tt + 80

(Refer to image)
Plug in x and z and follow order of operations to simplify the expression
Answer:
-5 <x<-1
Step-by-step explanation:
4|x+3|<8
Divide by 4
4|x+3| /4<8/4
|x+3|<2
There are two solutions one positive and one negative, remember to flip the inequality for the negative
x+3 <2 and x+3 >-2
Subtract 3 from each side
x+3-3 <2-3 and x+3-3 >-2-3
x<-1 and x>-5
-5 <x<-1
