The difference of 3 times a number and 15 is no less than the square of the number.

jok3333 [9.3K]

Answer:

(B) The inequality that represents this relationship is $3x < x^2 +15$

Step-by-step explanation:

Let us assume the given number = x

⇒ 3 times the given number = 3 (x) = 3x

Square of the given number = $(x)^2 = x^2$

Now, According to the question:

The difference of (3 x) and 15 is no less than $x^2$

⇒ $3x - 15 < x^2\\ \implies 3x < x^2 +15$

or, $3x < x^2 +15$

Hence, the given inequality is represented as $3x < x^2 +15$

It will cost Amber an estimated $3,723 a year in tuition to attend her preferred college. She has been putting $350 a month in a

kenny6666 [7]

Answer:

Yes; she will have $4008 for other expenses.

Step-by-step explanation:

First you find out how much she saved by multiplying 350 by 36 as she saved for 3 years which is 36 months.

$350 \times 36 = 12600$

After that you need to work out the amount she needs in total for her tuition by multiplying 4 by 3723 which is the amount needed per year.

$3723 \times 4 = 14892$

If her parents add to her account half the amount she saved that means that they give her an additional 6300 as that's half of 12600.

This means she has 18900 and if you take away 14892 you will be left with 4008 for expenses.

Identify the postulate that proves the triangles are congruent.

Ratling [72]

Answer:

ASA

Step-by-step explanation:

Triangle ABD is congruent to triangle BDC by ASA because angle B in ABD is 30 degrees. Then they give you BD which equals BD by the reflexive property. And finally angle D in ABD is also 30 degrees. In triangle BCD, angle B is 30 degrees, BD = BD, and angle D in BCD is 30 degress. So we have an angle (B), side (BD), and another angle (D)
