Answer:
3x^2 + 3 --> 6, 15, 30, 51
2x^2 - 1 --> 1, 7, 17, 31
x^2 + 2 --> 3, 6, 11, 18
Step-by-step explanation:
Let's start with the first equation; 3x^2 + 3
Substitute 1 (the first digit in a sequence) for x.
3(1^2) + 3
3(1) + 3
3 + 3 = <u>6</u>
3(2^2) + 3 Then the second digit.
3(4) + 3
12 + 3 = <u>15</u>
Since the two numbers we have so far are 6 and 15, there is only one sequence this could match. 6, 15, 30, 51.
2(1^2) - 1
2(1) - 1
2 - 1 = <u>1</u>
This equation represents 1, 7, 17, 31.
These same steps apply to the other equation as well.
1^2 + 2, then 2^2 + 2, then 2^2 + 2, and so on. (But we don't need to do extra work to figure that out.)
Step-by-step explanation:
<h3>Part A</h3>
At least 30 miles but less than 50 miles each week.
<u>Required inequality:</u>
<u>In 4 weeks:</u>
<h3>Part B</h3>
- "At least" means equal or more than 30, hence 30 ≤ x
- Less than 50, hence x < 50
<h3>Part C</h3>
At least 8 but no more than 12 gallons of gas each week, with the cost $2.25 to $2.50 per gallon.
<u>Match the lowest and highest ends. This is converted as:</u>
