Answer:
parabola
Step-by-step explanation:
Parabola: In mathematics, the term "parabola" is described as a specific plane curve that is considered as "mirror-symmetrical" and is approximately considered as being in a U-shaped. However, it tends to fit other mathematically different descriptions superficially that can all be said to proved to describe the similar curves. However, one single description associated with a parabola is being involved in a line or a point.
In the question above, the given statement represents parabola.
Answer:
x >
OR x > -2.33
Step-by-step explanation:
<em><u>The first step is to subtract 8 from both sides, like so:</u></em>
-3x + 8 < 15
- 8 - 8
__________
-3x < 7
<em><u>Divide both sides by -3:</u></em>
x <
<u>Whenever, you multiply/divide by a negative number, you must flip the inequality sign around. In this case, we divided by a negative:</u>
x >
OR x > -2.33
3000*10=30000
30000+200=30200
Answer:
I am guessing the answer would be...
A. (2.2)
Step-by-step explanation:
A proportional relationship is a relationship where the ordered pairs are the same. 2 and 2 are the same.

Answer: 4 minutes</h3>
============================================================
Explanation:
Let's say that this tub is 72 gallons. I picked this number since 12*6 = 72. You can pick any number you want, but I picked this number so we end up with whole number results as shown below.
Tap X can fill the 72 gallon tub in 12 minutes. Its rate is 72/12 = 6 gallons per minute. Tap Y has a rate of 12 gallons per minute because 72/6 = 12.
Add the two unit rates: 6+12 = 18
If the two taps are opened at the same time, then they will work at a rate of 18 gallons per minute.
Let x be the number of minutes. The expression 18x represents how much of the tub is full after x minutes. Set this equal to the 72 we started with earlier and solve for x.
18x = 72
x = 72/18
x = 4
It will take 4 minutes if both taps are running at the same time.
