Answer with explanation:

Rational numbers are those numbers which can be written in the form of \frac{a}{b} , where , b≠0.

Rational number can be written in the following way:

  Integers + Terminating Decimal + Non terminating Repeating Decimal

When you will look at , fraction \frac{1}{5}, it is terminating Decimal.

So, apart from any irrational number which is non terminating non repeating , if you multiply  \frac{1}{5}, with any number on the number line , that is any rational number ,because product of two rational is always a rational ,you will get a rational number.

Y=x^2+bx+c;(-2,3)
Maksim231197 [3]
<h3>Answer:  b = 4 and c = 7.</h3>

===============================================

Explanation:

Comparing y = x^2+bx+c to y = ax^2+bx+c, we see that a = 1.

The vertex given is (-2,3). In general, the vertex is (h,k). So h = -2 and k = 3.

Plug those three values into the vertex form below

y = a(x-h)^2 + k

y = 1(x-(-2))^2 + 3

y = (x+2)^2 + 3

Then expand everything out and simplify

y = x^2+4x+4 + 3

y = x^2+4x+7

We see that b = 4 and c = 7.

A box is 50 cm long. Which of these is closest to the length of this box in feet? (1 inch = 2.54 cm)
goblinko [34]

First, convert cm to inches.

50/2.54 is roughly 19.69

There are 12 inches in a foot, so divide the 19.69 by 12.

19.69/12 is roughly 1.64

So the answer is C

Solve 15 ≥ -3x or 2/5 x ≥ -2.
ipn [44]

Answer:

x ≥ -5

Step-by-step explanation:

15≥-3x

<em>switch sides</em>

<em>-3x≤15</em>

<em>Multiply both sides by -1 (reverse the inequality)</em>

<em>(-3x)(-1)≥15(-1)</em>

<em>Simplify</em>

<em>3x≥-15</em>

<em>Divide both sides by 3</em>

<em>3x/3≥ -15/3</em>

<em>Simplify</em>

<em>x≥ -5</em>
