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

I hope this helps!!!!

I really tried my best to explain so please let me know if this did or did not make sense

Parallel lines always have the same slope to each other

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:

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.

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.

Step-by-step explanation:

Answer:

They are similar.

Step-by-step explanation:

They are similar because, the top triangle has one more square to the height as well as the width. If you take one square away from the height and width the top triangle is the same size as the bottom triangle.

Answer:

-11

8 = 2x + 30

8 - 30 = -22

-22 ÷ 2 = -11

x = -11

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

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:

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:

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:

[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:

Step-by-step explanation:

Mark gave 1.80 tip which was 20% of the meal

1.80...................20%

? ........................100%

the meal was 9 dollars ,  1.80*5=9

second problem

finance charge was 15% which amounts 39.00 dollars

if 15% is 39 dollars

5% is 39/3=13

100% is 13*20=260

260 was the original price

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
