Answer:
12.5
Step-by-step explanation:
2. x is less than or equal to -5
So x could be -5, -6, -7, -8, -9, -10.....and so on
3. 16 is less than x, or x is greater than 16
So x could be any number greater than 16
4. x + 9 > 21; x = 10
Since you know "x", plug it in
x + 9 > 21
10 + 9 > 21
19 > 21
It is NOT a solution because 19 is NOT greater than 21
5. 3x < 45; x = 20
Plug in x
3x < 45
3(20) < 45
60 < 45
It is NOT a solution because 60 is NOT less than 45
6. 2x - 15 ≥ 5; x = 10
Plug in x
2x - 15 ≥ 5
2(10) - 15 ≥ 5
20 - 15 ≥ 5
5 ≥ 5
It IS a solution because 5 IS greater than or equal to 5
7. You see how the dot is filled in or not filled in? The dot is filled in when the sign is ≤ or ≥ ("less/greater than <u>or equal to</u>") The dot is NOT filled in when the sign is < or >.
Since the arrow is going to the left of 6, that means that "x" is any number less than 6
x < 6
8. The dot is filled in and the arrow is going to the left of -3, that means "x" is less than or equal -3
x ≤ -3
9. The dot is not filled in, and the arrow is going to the right of 0, that means that "x" is any number greater than 0
x > 0

The monthly interest rate charge is $165. The total principal payment you are making is $367.10+$165.00=$532.10
Answer:
The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.

Answer:
B. 2 laps per minute
Step-by-step explanation:
<em>Speed = distance/time</em>
- Distance = 30 laps
- Time = 15 minutes
<u>Speed is:</u>
- 30 laps / 15 min = 2 laps / min
<u>Correct answer option:</u>
