Write an equation of a line with the given slope and y-intercept. m = 1/4 b = - 3/4

Formula: V = PI x r^2 x H

Volume = 3.14 x 4^2 x 10

Volume = 3.14 x 16 x 10

Volume = 3.14 x 160

Volume = 160π or 502.4 units^3

To find the volume of a cylinder, we use the formula represented below.

Volume = [tex]\pi[/tex][tex]r^{2}[/tex]h

Notice that our cylinder has a radius of 4 and a height of 16, so we can plug these numbers into our formula.

Answer:

-x - 7y

Step-by-step explanation:

First, get rid of the parentheses by multiplying them out. Multiply them by one for them to go away.

Now, you have 1(3x - 2y) - 1(4x + 5y).

Now simplify, and it's 3x - 2y - 4x - 5y (Yes, -5y! It's beause -1 * 5y = -5y. The sign is supposed to change).

Ok. The next is easy: Identify your matching variables.

3x , -4x and -2y , -5y

So, we're going to assume x comes before y in the new equation, as that's how it is alphabetically, and that's it.

-x - 7y.

ANSWER

B. Function g has slope 3 which makes it steeper

EXPLANATION

The function f(x) has equation:

3x-y=6

We slope for y to get:

-y=-3x+6

y=3x-6

The slope of this function is 3.

The function g(x) passes through (-2,1) and (0,5).

The slope is

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

[tex]m = \frac{5- 1}{0 - - 2} [/tex]

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

Function g has slope 3. Hence it is steeper.

The statement which correctly compares the slopes of two functions is:

If the slope of a function has a greater absolute value as compared to other then that function is steeper than the other.

Here we have a function f(x) as:

[tex]3x-y=6[/tex]

On changing to slope-intercept form of a line

i.e. y=mx+c

where m is the slope of the line and c is the y-intercept of the line we have:

[tex]f(x)=y=3x-6[/tex]

i.e. the  slope of function f(x) is: 3

The function g(x) is a graph that passes through (-2,1) and (-1,3)

The equation for y=g(x) is given by:

[tex]y-1=\dfrac{3-1}{-1-(-2)}\times (x-(-2))\\\\\\y-1=\dfrac{2}{-1+2}\times (x+2)\\\\\\i.e.\\\\\\y-1=\dfrac{2}{1}\times (x+2)\\\\\\i.e.\\\\\\y=2x+4+1\\\\\\i.e.\\\\\\y=2x+5[/tex]

( since we used a concept of a line passing through two-point (a,b) and (c,d) is given by the equation:

[tex]y-b=\dfrac{d-b}{c-a}\times (x-a)[/tex] )

Hence, the slope of function g(x) is: 2

The absolute value of slope of function f(x) is greater than function g(x)

( since 3>2 )

Hence, we get function f(x) is more steeper.

Answer:

>6x=25<

Step-by-step explanation:

You will take the numbers (however many) multiply them and then use the two signs (greater than less than) to figure which it is. For additional help ask your teacher :)

Thank of it this way:

2 > 1 : this means that this little Pac-Man want to eat the bigger number so it would be the same if you have

1 < 2 : here 2 it's still greater then 1

1/2 = 0.5 : here we don't have a pacman but you know that 1/2 It's actually 0.5

So now if you have:

2n > -4 [divide by 2]

n > -2

And if you have a (image) Then this means that x is greater that -2 but it's less than 1, so x would be between -2 and 1

Hope this helps, ask any questions if you have.

a rectangle and a square

A rectangle & a square

Answer:

ab

Step-by-step explanation:

Since the terms all have the variable ab then they are like terms.

Collect them by adding/subtracting the coefficients

ab(3 - 9 + 7)

= 1ab = ab ← the 1 is assumed

The expression 3ab - 9ab + 7ab simplifies to ab by combining like terms.

The student is asking to simplify the algebraic expression 3ab - 9ab + 7ab. This involves combining like terms. As all terms are multiples of ab, we can add and subtract them as coefficients:

3ab - 9ab + 7ab = (3 - 9 + 7)ab = 1ab = ab

The rules followed here are analogous to the rules of arithmetic addition and subtraction. This concept is fundamental as it provides a foundation for simplifying expressions and solving equations in algebra.

Answer:

B. 0.08

Explanation:

The general form of a linear equation is:

y = mx + c

where:

m is the slope or the rate of change (increase or decrease)

c is the y-intercept or the initial value

Therefore, in a linear equation, the slope simply gives us the rate of change of the function (increase/decrease)

Now, the given equation is:

y = 0.08x + 5

Comparing the given equation with the general form, we will find that:

m = 0.08

Therefore, the cost of water increase for every gallon (rate of change) is 0.08

Answer:

x = -2 or x = sqrt(13)/2 - 3/2 or x = -3/2 - sqrt(13)/2

Step-by-step explanation:

Solve for x:

x^3 + 5 x^2 + 5 x - 2 = 0

The left hand side factors into a product with two terms:

(x + 2) (x^2 + 3 x - 1) = 0

Split into two equations:

x + 2 = 0 or x^2 + 3 x - 1 = 0

Subtract 2 from both sides:

x = -2 or x^2 + 3 x - 1 = 0

Add 1 to both sides:

x = -2 or x^2 + 3 x = 1

Add 9/4 to both sides:

x = -2 or x^2 + 3 x + 9/4 = 13/4

Write the left hand side as a square:

x = -2 or (x + 3/2)^2 = 13/4

Take the square root of both sides:

x = -2 or x + 3/2 = sqrt(13)/2 or x + 3/2 = -sqrt(13)/2

Subtract 3/2 from both sides:

x = -2 or x = sqrt(13)/2 - 3/2 or x + 3/2 = -sqrt(13)/2

Subtract 3/2 from both sides:

Answer:  x = -2 or x = sqrt(13)/2 - 3/2 or x = -3/2 - sqrt(13)/2

PENTA = 5.

a regular polygon has all equal sides, so if one side is 5.8, all are, so the perimeter for this pentagon with 5 sides is 5.8 + 5.8 + 5.8 + 5.8 + 5.8 = 29.

[tex]\bf \textit{area of a regular polygon}\\\\ A=\cfrac{1}{2}ap~~ \begin{cases} p=perimeter\\ a=apothem\\ \cline{1-1} p=29\\ a=4 \end{cases}\implies A=\cfrac{1}{2}(4)(29)\implies A=58[/tex]

Answer:

A. 9 ft

Step-by-step explanation:

Given that volume of the pyramid = 90 cu. ft.

Given that area of the base of the pyramid = 30 sq. ft.

Now we need to find about what is the height of the pyramid.

So plug the given values into formula of the volume of the pyramid

[tex]volume=\frac{1}{3}\left(Base\ Area\right)\left(Height\right)[/tex]

[tex]90=\frac{1}{3}\left(30\right)\left(Height\right)[/tex]

[tex]90=\left(10\right)\left(Height\right)[/tex]

[tex]\frac{90}{10}=Height[/tex]

[tex]9=Height[/tex]

Hence correct choice is A. 9 ft

Answer: Third option

The region shaded above a solid boundary line

Step-by-step explanation:

The limit for inequality [tex]y\geq\frac{1}{3}x[/tex] is the line [tex]y=\frac{1}{3}x[/tex].

Note that the inequality includes all values of y that are greater than or equal to the function [tex]f(x)=\frac{1}{3}x[/tex]. . This means that the region includes all values of y that are above the line [tex]f(x)=\frac{1}{3}x[/tex]. .

Remember that inequality includes values that are greater than or equal to the line [tex]f(x)=\frac{1}{3}x[/tex], therefore all values belonging to the limit line [tex]f(x)=\frac{1}{3}x[/tex], are also part of the region. This is represented by delimiting the region with a solid line

Finally the answer is the third option

Step-by-step explanation:

If was right on my assignment

Quadrilateral ABCD is a rhombus and parallelogram.

A parallelogram is a particular instance of a rhombus. The opposing sides and angles in a rhombus are parallel and equal. A rhombus also has equal-length sides on each side, and its diagonals meet at right angles to form its shape. The rhombus is also referred to as a diamond or rhombus.

Given, in a quadrilateral ABCD,

AB= BC = CD = DA

Since A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal). A parallelogram with all right angles is known as a rectangle, while a quadrilateral with equal sides is known as a rhombus.

A Quadrilateral is a Parallelogram, if any of this is possible in a Quadrilateral

Answer:

(x, y) = (-2, 2)

Step-by-step explanation:

We are given the following two equations which we are to solve using the substitution method:

[tex]x - y = -4[/tex] --- (1)

[tex]x - 2y = -6[/tex] --- (2)

From equation (1):

[tex]x = y-4[/tex]

Substituting this value of x in (2) to get:

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

y = 2

Substituting the value of y in (1) to get x:

[tex]x - y = -4[/tex]

[tex]x - 2 = -4[/tex]

[tex]x = -4 + 2[/tex]

x = -2

Therefore, (x, y) = (-2, 2).

The expression x(x + 9) + 20x + 5 is equivalent to x² + 29x + 5.

Explanation:

To simplify the expression x(x + 9) + 20x + 5, we can distribute the x to both terms inside the parentheses:

x * x + x * 9 + 20x + 5

This simplifies to:

x² + 9x + 20x + 5

Combining like terms, we get:

x² + 29x + 5

Therefore, the expression x(x + 9) + 20x + 5 is equivalent to x² + 29x + 5.
