Answer:
I think you would have to draw lines like is the graph book, you will see that they have two axes which is the y and the x.You will then have to fix in numbers and indicate the y= 2x+1.
Step-by-step explanation:

Amounttotal=amount per day times number of days
200=17.1 times d
divide both sides by 17.1
11.695=d
about 12 days
we have in this problem
------> inequality
------> inequality
<u>Solve the inequality </u>
the solution is the interval------> (3,∞)
<u>Solve the inequality </u>
the solution is the interval------> (-∞,5]
<u>Find the solution for the system</u>
(3,∞) ∩ (-∞,5]--------> (3,5]
therefore
<u>the answer is the option</u>
A. A number line with an open circle on 3, a closed circle on 5, and shading in between.
Time taken for the boats to meet will be given by:
time=(distance)/(speed)
relative speed=(speed of boat A+speed of boat B)
speed of boat A=2.5 mph
speed of boat B=2(2.5)=5 mph
thus
relative speed=(5+2.5)=7.5 mph
distance=30 miles
thus
time=30/7.5=4 hours
thus the earliest they can meet is 4 hours
1 + 2x - 7 = 3x + 5 - 3x
Combine like terms
2x - 6 = 5
Isolate the x value on one side of the equation
2x = 11
Divide both sides by the number in front of the x
x = 11/2 or 5.5
