Answer:
x = 4
Step-by-step explanation:
1) Substitute the given x values, by substitution you replace x with the numbers provided. We do this because since the numbers are already given you are to find the correct value of y.
2) Plug in the numbers provided.
Start with x = 3
2(3) + 3 = 11
2 * 3 = 6
6 + 3 = 9
x = 3 is not a correct choice
2) Use the second option and determine if the second option is correct.
x = 4
2(4) + 3 = 11
4 * 2 = 8 + 3 = 11
This option is correct because the value of x makes the equation true.
Answer:
The time it will take Natalie to pick the forty bushels alone is 10 hours
Step-by-step explanation:
The time it takes Kali to pick forty bushels of apples alone = 15 hours
The time it takes Kali and Natalie to pick forty bushels = 6 hours
The rate at which Kali picks bushels = 40/15 bushels per hour = 8/3 bushels per hour
Let x represents the rate at which Natalie picks bushels, we have;
8/3 × 6 + x × 6 = 40
x × 6 = 40 - 8/3 × 6 = 24
x = 24/6 = 4
Therefore;
The rate at which Natalie picks the bushels of apples = 4 bushels/hour
The time it will take Natalie to pick the forty bushels alone = (40 bushels)/(4 bushels/hour) = 10 hours.

- Solving systems of equations by graphing
Step-by-step explanation:
The solution set of the systems would be where the 2 lines intersect. We see from the graph that our 2 lines intersect at (2, 6). Therefore, our solution set would be D. (2, 6).
