According to the number line, the statement that MUST be true- is (C) C < 15

<u>c) We can see that √C is almost equal to 4, and 4^2 = 16, so most likely, C is bigger than 15, so this is true</u>

<u></u>

<u></u>

<u>Step-by-step explanation:</u>

As you know, in the number line we are looking at the roots of the numbers, and as you know; (√A)^2 = A, so using this, we can analyze each option:

a) A can not be less than zero, because √A is bigger than zero.

b) we can see that √B is smaller than 3, and 3^2 = 9, so B must be smaller than 9, and then, smaller than 10.

<u>c) We can see that √C is almost equal to 4, and 4^2 = 16, so most likely, C is bigger than 15, so this is true</u>

d) we can see that √D is bigger than 4, and using the same reasoning as before, we can see that D is bigger than 16, and 16 is bigger than 15, so D > 15 is false

Given X(4, -7). What are the coordinates of X" if
Vika [28.1K]
<h3>Answer:</h3>

B. (0, 9)

<h3>Step-by-step explanation:</h3>

Reflection across x=a is represented by the transformation ...

... (x, y) ⇒(2a-x, y)

Reflection across y=b is represented by the transformation ...

... (x, y) ⇒ (x, 2b-y)

The double reflection, across x=2, y=1 will result in the transformation ...

... (x, y) ⇒ (2·2-x, y) ⇒ (4-x, 2·1-y) ⇒ (4-x, 2-y)

For (x, y) = X(4, -7), the transformed point is ...

... X''(4-4, 2-(-7)) = X''(0, 9)

Does anyone know how to solve |4x+3|-9&lt;5
elixir [45]

Answer in fraction form:   -17/4 < x < 11/4

Answer in decimal form:   -4.25 < x < 2.75

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

Work Shown:

|4x+3| - 9 < 5

|4x+3| < 5+9 .... adding 9 to both sides

|4x+3| < 14

-14 < 4x+3 <  14 .... see note at the bottom

-14-3 < 4x < 14-3 .... subtracting 3 from all sides

-17 < 4x < 11

-17/4 < x < 11/4 .... divide all sides by 4

-4.25 < x < 2.75

This says that x is between -4.25 and 2.75, but x is not equal to either endpoint.

Note: I used the rule that |x| < k becomes -k < x < k where k is a positive real number.

Beinggreat78 answer fast please :')
Dovator [93]

Answer:

17662.5 sq. feet

Step-by-step explanation:

We know that the formula for Area of a Circle is A = \pi (r)^2.

r = radius; d = diameter, which is r*2


And so, in the question, it gives you that the diameter is 150, first we divide it by 2 to get the radius.

150/2 = 75

The question said to keep \pi =3.14, so then we plug in the equation-

A = 3.14 * 75^2


Then we use PEMDAS [Parenthesis; Exponents; Multiply & Divide; Add & Subtract] which would get us-

A = 3.14 * 5625 (first doing the Exponent)

And we continue-

A = 17662.5 (then multiple)

So our answer is-

17662.5 sq. feet

I hope this helps!
