Your answer should be 6.4 if you attempt to solve this. I hope this helps your question!
(2,1) is the solution because its where they both intersect..
For problem 2:
The answer would be B) Car A travels more miles per gallon of fuel than Car B.
This is because Car B is shown on the graph to travel the same number of miles as Car A using 16 gallons of fuel, while Car A uses only 4 gallons. Thus, Car A travels further with less fuel.
For problem 3:
Let's write out the equation and try to solve.
5x + 1 = 3x + 7
First, subtract 3x from both sides.
5x - 3x + 1 = 3x - 3x + 7
2x + 1 = 7
Now, subtract one from both sides.
2x + 1 - 1 = 7 - 1
2x = 6
Finally, divide both sides by 2.
2x/2 = 6/2
x = 3
You should only get B) One solution
Hope that helped!
Answer:
x < -10/7
Step-by-step explanation:
Divide both sides by -7. Because this divisor is negative, we must reverse the direction of the inequality sign, obtaining:
-7x < 10
----- < -----
-7 -7
Then x < -10/7
