Add 7 to both sides
3x + 12 = 7x
Subtract 3x
12 = 4x
Divide by 4
x = 3

Is it true that (x + 3)2 = x2 + 9? Justify your answer.
Katena32 [7]

Answer:

No

Step-by-step explanation:

3 times 2 is 6 and 2 times x is 2x so therefore 2x+6 does not equal 2x+9. Hope this helps!

the phrase “is a function of” gets used in non-mathematical speech as well as mathematical mathematical speech in sentences like
Tanya [424]

Answer:

Step-by-step explanation:

This is a very interesting question. I'm going to answer no, but don't take that to mean that the question is not worthwhile. It is.

In math, function has the meaning of considering ordered pairs. Here are 4 such ordered pairs.

(1,2)

(2,4)

(1,-3)

(5,9)

They are really not related to one another except all are ordered pairs.

Here's the math definition. If one of the x values (1,2,1,5) has more than 1 y value, you do not have a function.

1 has 2 y values,  2 and -3. Therefore the 4 points do not form a function

if you change the first (1,__) to 0 and your ordered pair becomes (0,2), all is well and you do have a function.

Whether you understand this or not, you have to see that a math function and a biology function are very different. The math function has numbers and those numbers have to obey a rule.

The biology function seems to be saying that how your mom and dad brought you up will determine what foods you like.

Those two uses are very different. How your mom brought you up is related to food. It could be anything else like "Being a knife carrying gang member is a function of where you live."

Air balloon #1 is 10 meters above the ground rising 15 meters per minute. Air balloon #2 is 150 meters about the ground descendi
Burka [1]
 Remember that Distance = Speed x Time

When the 2 Balloons meet, they will be at the same height FROM THE GROUND :

Distance travelled by #1 : 10 + 15.Time
Distance travelled by #2 : 150 - 20.Time (the descending speed is negative)
Since it's the same distance from the ground, we can write:

10 + 15.Time =150 -20.Time 
15.Time + 20.Time = 150 - 10
35.Time = 140

And Time = 4 minutes

Now take any equation and plug in Time = 4:

10 + 15.Time = 10+15x4 = 70 meters

OR

150 - 20.Time = 150-20x4 = 70 meters
