Answer:

Is there a picture for this one and also you didn't mention the slope of the red line is?

Step-by-step explanation:

Answer:

The slope of the Green line should be the same as the red line- but a negative number instead of a positive.

Step-by-step explanation:

This is the inverse of the line

So by reflecting it over the y-axis, the slope remains the same but will change from positive to negative and vise versa

Answer:

f(-2)=45

Step-by-step explanation:

f(x)=5(x+11)

x= -2

so basicly its just 5(-2+11)

which is -10+55 and that is 45

so f(-2)=45

Considering the given function, it is found that the numeric value at x = -2 is of f(-2) = 45.

The function is defined by:

f(x) = 5(x + 11).

Hence, when x = -2, we have that:

f(-2) = 5(-2 + 11) = 5 x 9 = 45.

Step-by-step explanation:

4 cups of orange juice + 3 cups of cranberry juice = 7 cups of fruit punch

28 = 4 * 7 so all you would need to do is multiply the number of cups by 4

4( 4 cups of orange juice + 3 cups of cranberry juice = 7 cups of fruit punch)

16 cups of orange juice + 12 cups of cranberry juice = 28 cups of fruit punch

Answer:

equation : 2x + 4 = 3x - 5

X = 9

BC = 22

The equation will be - (2x + 4 = 3x - 5), x = 9 and BC = 22.

In Euclidean geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles. It can also be defined as a rectangle with two equal-length adjacent sides.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.

A mathematical equation is used to equate two expressions.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is square ABCD and AB = 2x + 4 and CD = 3x - 5

Now -

AB = CD

Equation will be -

2x + 4 = 3x - 5

4 + 5 = 3x - 2x

x = 9

and

AB = BC = CD = AD = 2x + 4 = 2 x 9 + 4 = 22

BC = 22

Therefore, the equation will be - (2x + 4 = 3x - 5), x = 9 and BC = 22.

Answer:

x = [tex]\frac{-1}{3}y[/tex] + [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

16 - 12x = 4y

Add -16 to both sides.

-12x + 16 + (-16) = 4y + (-16)

-12x = 4y - 16

Then divide both sides by -12

-12x / (-12) = [tex]\frac{4y-16}{-12}[/tex]

x = [tex]\frac{-1}{3}y[/tex] + [tex]\frac{4}{3}[/tex]

Answer:

22,950

Step-by-step explanation:

subtract 51,550 and 28,600. 0 - 0 = 0 then 5-0=5 5-6 you can not do so you barrow from the 1. 1 becomes 0 and 5 becomes 15. 15-6=9. 0-8 you can not do so you need to borrow from the 5. 5 becomes 4 and 0 becomes 10. 10-8=2. Finally, 4-2=2. Put is all together and you have 22,950.

Given:

The equation is

[tex]3x+4y=24[/tex]

To find:

The x- and y-intercepts of the given equation.

Solution:

We have,

[tex]3x+4y=24[/tex]

Putting x=0, we get

[tex]3(0)+4y=24[/tex]

[tex]0+4y=24[/tex]

[tex]y=\dfrac{24}{4}[/tex]

[tex]y=6[/tex]

Therefore, the y-intercept of the given equation is 6.

Putting y=0, we get

[tex]3x+4(0)=24[/tex]

[tex]3x+0=24[/tex]

[tex]x=\dfrac{24}{3}[/tex]

[tex]x=8[/tex]

Therefore, the x-intercept of the given equation is 8.

Answer:

Undefined

Step-by-step explanation:

We see that the domain of f is (-5,5], where ( means not included, ] means included.

Therefore, since -5 is not in the domain, the value is undefined.

Answer:

-11

8 = 2x + 30

8 - 30 = -22

-22 ÷ 2 = -11

x = -11

Also if you place 2×(-11) + 30 you get 8

Answer:

[tex]\frac{1}{2\sqrt{5} }[/tex]

Step-by-step explanation:

Let, [tex]\text{sin}^{-1}(\frac{x}{6})[/tex] = y

sin(y) = [tex]\frac{x}{6}[/tex]

[tex]\frac{d}{dx}\text{sin(y)}=\frac{d}{dx}(\frac{x}{6})[/tex]

[tex]\frac{d}{dx}\text{sin(y)}=\frac{1}{6}[/tex]

[tex]\frac{d}{dx}\text{sin(y)}=\text{cos}(y)\frac{dy}{dx}[/tex] ---------(1)

[tex]\frac{1}{6}=\text{cos}(y)\frac{dy}{dx}[/tex]

[tex]\frac{dy}{dx}=\frac{1}{6\text{cos(y)}}[/tex]

cos(y) = [tex]\sqrt{1-\text{sin}^{2}(y) }[/tex]

          = [tex]\sqrt{1-(\frac{x}{6})^2}[/tex]

          = [tex]\sqrt{1-(\frac{x^2}{36})}[/tex]

Therefore, from equation (1),

[tex]\frac{dy}{dx}=\frac{1}{6\sqrt{1-\frac{x^2}{36}}}[/tex]

Or [tex]\frac{d}{dx}[\text{sin}^{-1}(\frac{x}{6})]=\frac{1}{6\sqrt{1-\frac{x^2}{36}}}[/tex]

At x = 4,

[tex]\frac{d}{dx}[\text{sin}^{-1}(\frac{4}{6})]=\frac{1}{6\sqrt{1-\frac{4^2}{36}}}[/tex]

[tex]\frac{d}{dx}[\text{sin}^{-1}(\frac{2}{3})]=\frac{1}{6\sqrt{1-\frac{16}{36}}}[/tex]

                   [tex]=\frac{1}{6\sqrt{\frac{36-16}{36}}}[/tex]

                   [tex]=\frac{1}{6\sqrt{\frac{20}{36} }}[/tex]

                   [tex]=\frac{1}{\sqrt{20}}[/tex]

Answer: f (4) = 9

Answer:

8

Step-by-step explanation:

here,

4x+4=9x-36

or,4+36=9x-4x

or,40=5x

or40/5=x

or,8=x

x=8

6x - 2 + 2x = -2 + 4x + 8

Simplifying

6x + -2 + 2x = -2 + 4x + 8

Reorder the terms:

-2 + 6x + 2x = -2 + 4x + 8

Combine like terms: 6x + 2x = 8x

-2 + 8x = -2 + 4x + 8

Reorder the terms:

-2 + 8x = -2 + 8 + 4x

Combine like terms: -2 + 8 = 6

-2 + 8x = 6 + 4x

Solving

-2 + 8x = 6 + 4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.

-2 + 8x + -4x = 6 + 4x + -4x

Combine like terms: 8x + -4x = 4x

-2 + 4x = 6 + 4x + -4x

Combine like terms: 4x + -4x = 0

-2 + 4x = 6 + 0

-2 + 4x = 6

Add '2' to each side of the equation.

-2 + 2 + 4x = 6 + 2

Combine like terms: -2 + 2 = 0

0 + 4x = 6 + 2

4x = 6 + 2

Combine like terms: 6 + 2 = 8

4x = 8

Divide each side by '4'.

x = 2

Simplifying

x = 2
