if x=4 what is y when y=-2x-4​

The formula to find the circumference of a circle is 2 x pi (π) x radius. The radius is half of the diameter. Therefore, since the diameter is 20, the radius is 10. Pi is equal to approximately 3.14.

3.14 x 10 x 2 is 62.8.

The circumference of the circle is 62.8 m.

Answer:

y = 3/4x - 2

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Step 1: Define

(0, -2) y-intercept

(4, 1) random point

Step 2: Find slope m

[tex]m=\frac{1-(-2)}{4-0}[/tex]

[tex]m=\frac{1+2}{4}[/tex]

[tex]m=\frac{3}{4}[/tex]

y = 3/4x + b

Step 3: Write linear equation

y = 3/4x - 2

Answer:

Option A

Step-by-step explanation:

Since left and right sides are equal:

[tex]x+x+x+x+(-1) +(-1) = x+1+1+1+1\\4x-2 = 4+x\\3x=6\\x=2[/tex]

Hope that helps.

Answer:

Step-by-step explanation:

On the left we have four x-es and two (-1) so: 4•x+2•(-1)

On the right we have one x and four (+1) so:  x+4•(+1)

The scarves of scales are balanced, therefore:

         4•x + 2•(-1) = x + 4•(+1)

               4x - 2  =  x + 4

                     -x        -x

                3x - 2 = 4

                    +2       +2

                   3x  =  6

                   ÷3     ÷3

                   x  =  2

Domain : { - 3 , - 1 , 0 , 2 }

Answer:

maybe 13 and 21

Step-by-step explanation:

because there all just adding

Add the two previous numbers for the next number:

1+ 1 = 2

2+ 1 = 3

3+ 2 = 5

5 + 3 = 8

Now add 5 and 8 : 5 + 8 = 13

Now add 8 and 13: 8 + 13 = 21

The two numbers are 13 and 21

Answer:

[tex] s = \sqrt[3]{V} [/tex]

Length of each side of the tank = 15 ft

Step-by-step explanation:

A cube has equal length sides.

Formula for the volume of a cube is given as [tex] V = s^3 [/tex], where,

s = side length of the cube.

Given that a tank, in the shape of a cube, holds 3,375 ft³ of water, to derive an equation for finding the length of each side of the tank, make "s" the subject of the formula as follows:

[tex] V = s^3 [/tex]

Take the cube root of both sides

[tex] \sqrt[3]{V} = \sqrt[3]{s^3} [/tex]

[tex] \sqrt[3]{V} = s [/tex]

[tex] s = \sqrt[3]{V} [/tex]

The above equation would be used to find the length of each side of the tank as follows:

[tex] s = \sqrt[3]{3,375} [/tex] (substitution)

[tex] s = \sqrt[3]{3,375} [/tex]

[tex] s = 15 [/tex]

Length of each side of the tank = 15 ft

Answer:

1/3

Step-by-step explanation:

Start at -4 and go over one to the right and up 3.

Answer:

D

Step-by-step explanation:

You are subtracting two functions to get the profit, the formula is p(x)=r(x)-c(x). You know what two of those functions are equivalent to so plug it in to get

p(x)=11x-(6x+20)

to solve you must first get rid of the parentheses by distributing the negative.

p(x)=11x-6x-20

then, combine like terms (both x's)

p(x)=5x-20

That is your final answer.

Answer:

g(3) = 0

Step-by-step explanation:

g(3) → x = 3 , in interval x≥ 3 , thus g(3) = - x + 3, that is

g(3) = - 3 + 3 = 0

Answer:

f(-2)=g(-2)

Answer:

The distance between the points (1, 7) and (10, 1) is 10.82 units

Step-by-step explanation:

Distance between two points

The distance between points A(x,y) B(w,z) can be calculated with the formula:

[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]

We are given the points (1,7) and (10,1), let's use their values and compute the required distance:

[tex]d=\sqrt{(1-7)^2+(10-1)^2}[/tex]

[tex]d=\sqrt{(-6)^2+(9)^2}[/tex]

[tex]d=\sqrt{36+81}=\sqrt{117}\approx 10.82[/tex]

The distance between the points (1, 7) and (10, 1) is 10.82 units

Answer:

30,000

Explanation:

This is less than 35000. And so we need to round the number down to the nearest ten thousand. And so if we round 34699 to the nearest ten thousand, it becomes 30000.

Answer:

35,000

Step-by-step explanation:

the explanation is that when rounding up from 34,699 it round up to

35,000 because 6 is greater than 5 which means you round up the number in front of the 5 through 9. 4 through 0. You round it to 0 so it would be 35,00.

Answer:

Irrational
