Answer:
See picture for the answer and steps!
Step-by-step explanation:
<span>use an expression
s = speed of the slower car
then
(s+20) = speed of the faster car
When they meet is after 400 miles
Write distance equation
slow car d + fast car d = 400 mi
4s + 4(s+20) = 400
8s + 80 = 400
8s = 400 - 80
8s = 320
s = 40 m/H</span>
All you have to do is place an open circle at X = 2 and draw an arrow pointing to the left of the number 2. Since this represents all values less than 2, and not including 2, are possible solutions to the following inequality.
