Answer:

Actually,there x is qual to ninty minus x because of vertically opposite side...cauce ninty minus x comes in vertical opposite side by dragging the ninty minus x down ...so finally x is equalto ninty minus x and two x is equal to nintynow divide ninty by nine it's your ans.

Answer:

A. 2x-4

Step-by-step explanation:

2x-4 since when you factor this expression, you get (2x-4)^2. a square has equal sides and is calculated by side length squared, so simply take the square root of the known area (2x-4)^2 and you get 2x-4.

Answer:

y = [tex]\frac{1}{2}[/tex] x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + 2 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex]

The line crosses the y- axis at (0, 1) ⇒ c = 1 , then

y = [tex]\frac{1}{2}[/tex] x + 1 ← equation of perpendicular line

Answer:

305966.4in³

Step-by-step explanation:

Given parameters:

Radius of the sphere = 41.8in

Unknown:

Volume of the sphere = ?

Solution:

The volume of sphere is expressed as:

   V  = [tex]\frac{4}{3} \pi r^{3}[/tex]  

r is the radius;

  Input the parameters and solve;

       V  = [tex]\frac{4}{3 }[/tex] x [tex]\pi[/tex] x 41.8³

     V  = 305966.42in³

To nearest tenth of a cubic inch;

    V = 305966.4in³

Answer:

2(12x + 10y)  

Step-by-step explanation:

The value of three expression that are equivalent to the given expression (24x + 20y) are,

⇒ 2 (12x + 10y)

⇒ 4 (3x + 5y)

⇒ 48/2x + 40/2y

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expression is,

⇒ 24x + 20y

Now, We can write the expression as,

⇒ 24x + 20y

⇒ 2 (12x + 10y)

⇒ 4 (3x + 5y)

⇒ 48/2x + 40/2y

Answer:

x≥-2

y<3

y≥x+3

Step-by-step explanation:

For x≥-2 the line is passing through -2 on the X axis

For y<3 the dotted line is passing through 3 on the y axis and as it is dotted it is just less than

For y≥x+3 the line is passing through -3 on the x axis and 3 on the y axis so it must be y=x+3. Then you apply the inequality so it becomes y≥x+3

Hope it helps :)

The inequalities to describe the shaded area on the grid​ are

[tex]\rm \bold {x\geq -2}\\\bold{y<3}\\\\bold{y \geq\ x+3}[/tex]

The shaded area of the grid is surrounded by three lines the equations of all three lines are given as below in form of inequalities.

For a solid line the " equality"  is included but for a dashed line " equality" is not included.

x ≥ -2

y < 3

The equation of third line can be found out by writing standard form of straight line

[tex]\rm y = mx +c \\m = Slope \;of\; the\; line\\c = y\; axis \; intercept \; value[/tex]

As we can observe from the figure that the line passes through (0,3) and (-3,0) and hence we write the equation of line as

[tex]\rm y = (3-0) /(0-(-3)) ( x+3) \\y = 1\times x + 3\\y = x+3 \\So \; the\; inequality\; can \; be\; written\; as\\y\geq x+3[/tex]

Since the area above the line y = x+3 is of our concern hence greater than equal to sign is used.

So the inequality for third line is

[tex]\rm\bold{ {y\geq x+3}}[/tex]

The inequalities to describe the shaded area on the grid​

[tex]\rm \bold {x\geq -2}\\\bold{y<3}\\\\bold{y \geq\ x+3}[/tex]

Answer:

The formula you'll need is:

Years = ln (total / principal) / rate

ln means natural log

Years = ln (2,000 / 1,000) / .045

Years = ln (2) / .045

Years = 0.69314718056 / .045

Years = 15.4033

Step-by-step explanation:

m<2 + m<3 = 90

m<5 + m<6 = 90

m<2 + m<3 + m<5 + m<6 = 90 + 90 = 180

Answer: 180

Answer:

11

Step-by-step explanation:

you do 2000 - 350

you would get 1650

and you divide it by 150

it would look like this 1650 ÷ 150 = 11

Second Problem

Again, let's get the givens out of the way. I'm lazy, so just put the things in the given section in the boxes.

3. Vertical angles             This is just a fun way of saying that the angles on top of each other are equal

4. AAS                                We have an angle, an angle and a side. Whack em' together and you get AAS

Step-by-step explanation:

Move the terms,

19 + 4h = 1 -5h

Combine like terms,

4h+5h=1-19

Divide both sides...

9h= -18

-18/9 = -2

Answer:

h=-2

Step-by-step explanation:

17+4h+2=1-5h

19+4h=1-5h

-1 -1

18+4h=-5h

-4h -4h

18=-9h

18/-9=-9h/-9

h=-2
