Answer:

If twice the opposite of a number increased by five, then the result is the opposite of a number.    

The asiest way to solve this is the guess and check method. It is asking you what a number doubled then by adding five is the opposite of that number. Now go through a few SINGLE digit numbers to try and solve. I hope this helps.

Find the area of a circle with the circumference 18(pi)
JulsSmile [24]

Answer:

D 81 pi units^2

Step-by-step explanation:

The circumference of a circle  is given by

C = 2 * pi *r

18 pi = 2 * pi *r

Divide each side by 2 * pi

18 pi / (2 pi) = 2 pi * r/ (2 pi)

9 = r

Now we can find the area.  Area is given by

A = pi r^2

A = pi * 9^2

A = 81 pi units^2

The circumference of a circle can be found using the formula C = 2r. Which is an equivalent equation solved for r? r = C r = C(2
vaieri [72.5K]

Answer:

r equals StartFraction C Over 2 pi EndFraction

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=2\pi r

where

r is the radius of the circle

Solve for r

That means -----> isolate the variable r

Divide by 2π both sides

\frac{C}{2\pi}=\frac{2\pi r}{2\pi}

Simplify right side

\frac{C}{2\pi}=r

Rewrite

r=\frac{C}{2\pi}

so

r equals StartFraction C Over 2 pi EndFraction

Can someone please help
AleksandrR [38]

Answer:

(x+5) and (x-7).

Step-by-step explanation:

The given equation is :

x^2-2x-35

We need to write it in factored form.

We know that,

7×5 = 35 and 7-5 = 2

So,

x^2-2x-35=x^2-7x+5x-35\\\\=x(x-7)+5(x-7)\\\\=(x+5)(x-7)

Hence, the required factors are (x+5) and (x-7).

Answer:

<u>Given function</u>

  • h(x) = 2x - 1

#15 Find the inverse of h(x)

<u>Substitute x with y and h(x) with x and solve for y:</u>

  • x = 2y - 1
  • 2y = x + 1
  • y = 1/2x + 1/2

<u>The inverse is:</u>

  • h⁻¹(x) = 1/2x + 1/2

#16 The graph with both lines is attached.

The x- and y-intercepts of both functions have reversed values.

#17 Table of the inverse function  will contain same numbers with swapped domain and range.

<u>Initial look is like this:</u>

  • <u>x        |  -3  |  -2  | -1  |  0  |    1  |  2  | 3</u>
  • h⁻¹(x)  |  -1   |       | 0   |      |    1  |      | 2

<u>The rest of the table is filled in by finding the values:</u>

  • <u>x        |  -3  |  -2    | -1  |  0   |  1  |  2   | 3</u>
  • h⁻¹(x)  |  -1   | -0.5 |  0  | 0.5 |  1  | 1.5 | 2

Divide 28 cans of soda into two groups so the ratio is 3 to 4
Natali5045456 [20]

Total units would be: 3+4 = 7

value of 1 unit = 28/7 = 4

ratio would be 3(4) & 4(4) = 12 & 16
