Find the value of x.

Answer:

The answers A

Step-by-step explanation:

Use ratios such that x1/y1= x2/y2

Need to find x2

So it works much easier if you use x as the numerator, giving 15/12=x/21

Multiply both sides by 21 and we have 21 x 15/12=x x 21/21

and 21/21=1 giving: x=21 x 15/12= 26 1/4

and in decimal form is 26.25

Answer: 262.6

Step-by-step explanation: Well if she sold 110 hamburgers on tuesday for $545 That is a simple division equation (545/110). After dividing the answer would be how much each hamburguer cost on its own ( 4.954545454545455), you would then multiply that by the number of hamburgers she sold (53) and get your answer. (262.5909090909091) I am not quite sure where she wants us to round the answer to. so I just did the tens place.

Answer:

The relation between the time and the distance will be:

y = 15x

The graph of the equation y = 15x is attached below.

Step-by-step explanation:

We know that the equation of linear function in two variables in the slope-intercept form is

y = mx+b

where

Let y be the distance

Let t be the time

Given that the object moves 15 meters in 1 second.

Thus, the rate of change or slope = m = 15

As there is no initial condition in our case.

Thus the y-intercept b = 0

Now, substituting m = 15 and b = 0 in the linear function

y = mx+b

y = 15x + 0

y = 15x

Therefore, the relation between the time and the distance will be:

y = 15x

The graph of the equation y = 15x is attached below.

Examples:

Calculate the distance in 1 second

put x = 1 in the equation

y = 15(1) = 15 meters

Calculate the distance in 10 second

put x = 10 in the equation

y = 15(10) = 150 meters

Answer:

Step-by-step explanation:

Simplifying

6x + -3 = (3x + -2)

Reorder the terms:

-3 + 6x = (3x + -2)

Reorder the terms:

-3 + 6x = (-2 + 3x)

Remove parenthesis around (-2 + 3x)

-3 + 6x = -2 + 3x

Solving

-3 + 6x = -2 + 3x

Solving for variable 'x'.

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

Add '-3x' to each side of the equation.

-3 + 6x + -3x = -2 + 3x + -3x

Combine like terms: 6x + -3x = 3x

-3 + 3x = -2 + 3x + -3x

Combine like terms: 3x + -3x = 0

-3 + 3x = -2 + 0

-3 + 3x = -2

Add '3' to each side of the equation.

-3 + 3 + 3x = -2 + 3

Combine like terms: -3 + 3 = 0

0 + 3x = -2 + 3

3x = -2 + 3

Combine like terms: -2 + 3 = 1

3x = 1

Divide each side by '3'.

x = 0.3333333333

Simplifying

x = 0.3333333333

Answer:

[tex](-21)^\frac{6}{5}[/tex]

Step-by-step explanation:

Which expression represents [⁵√(−21)]⁶ in rational exponent form?

Solution:

Rational numbers are numbers which can be expressed as fractions in the form a / b, where a, b are integers and b is not equal to zero.

A rational exponent is an exponent that is a fraction. For example √2 = [tex]2^\frac{1}{2}[/tex].

When expressing a number in rational exponent form, the numerator of the fractional exponent refers to a normal power, but the denominator refers to the root.

[tex][\sqrt[5]{(-21)}]^6 = (-21)^\frac{6}{5}[/tex]

Answer:

5$

Step-by-step explanation:

Given:

A transformation was performed on PQRS to form P'QʻR'S'.

To find:

The transformation.

Solution:

The given graph shows two similar polygons. It means, dilation was performed.

From the given graph it is clear that,

[tex]PS=2[/tex] units

[tex]P'S'=1[/tex] units

Now,

[tex]\text{Scale factor}=\dfrac{P'S'}{PS}[/tex]

[tex]\text{Scale factor}=\dfrac{1}{2}[/tex]

A dilation factor of [tex]\dfrac{1}{2}[/tex] was performed on PQRS to form P'QʻR'S'.

Therefore, the correct option is (3).

Answer:

2x+5y=13

y=x+7

Step-by-step explanation:

The linear functions are the ones Without exponents on the variables because the ones with exponents don't make a straight line. So:

2x+5y=13

y=x+7

Answer:

28%

Step-by-step explanation:

Answer: 28%

Step-by-step explanation:

1800/2500 = 0.72

0.72 = 72%

100% - 72% =  28%

Answer:

There are 8 3/4-cup servings.

Step-by-step explanation:

What we know:

There is a 6-cup container of milk.

What we don't know:

How many 3/4-cup servings are there?

What we should do:

Divide 6 by 3/4.

6 / 3/4

This is the same as 6 times 4/3.

6 * 4/3

24/3

There are 8 3/4-cup servings in a 6-cup container of milk.

Answer:

$0.216 and $0.293

Step-by-step explanation:

Given,

Price club sells 12 ounce box = $2.59

Shop mart sells a 1 pound box = $ 4.68.

We have to find the unit price at Price club and Shop mart.

We know that 1 Pound = 16 ounce

Unit price at Price-club = [tex]\dfrac{2.59}{12}[/tex]

                                      = $0.216

Unit price at Shop Mart= [tex]\dfrac{4.68}{16}[/tex]

                                      = $0.293

because I got this question too. On odysse.yware.

Answer:

0.21 and 0.19

Step-by-step explanation:

It's simple, just divide it.

Divide 2.59 by 12 and divide 4.68. Then round the answers to the closest number in the choices. That's your answer buddy!

Answer: allways increasing

Step-by-step explanation:

the graph line has arrows on the ends and it looks like it will always be going up

Given:

[tex]f(x)=4x-7[/tex]

[tex]g(x)=4x[/tex]

To find:

The expression for f(f(x)).

Solution:

We need to find f(f(x)).

[tex]f(f(x))=f(4x-7)[/tex]                             [tex][\because f(x)=4x-7][/tex]

[tex]f(f(x))=4(4x-7)-7[/tex]                             [tex][\because f(x)=4x-7][/tex]

Using distributive property, we get

[tex]f(f(x))=4(4x)+4(-7)-7[/tex]

[tex]f(f(x))=16x-28-7[/tex]

[tex]f(f(x))=16x-35[/tex]

Therefore, the expression for f(f(x)) is [tex]f(f(x))=16x-35[/tex].

Answer:

The coordinates of the other point are:

(x₂, y₂) = (18, 20)

Hence, option A is correct.

Step-by-step explanation:

Given

To determine

Using the Mid-point formula between (x₁, y₁) and (x₂, y₂)

[tex]\left(x,\:y\right)=\:\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

Here:

(x, y) is the midpoint between (x₁, y₁) and (x₂, y₂)

substituting (x, y) = (0, 5) and (x₁, y₁) = (-18, -10) in the formula

[tex]\left(0,\:5\right)=\:\left(\frac{x_2+\left(-18\right)}{2},\:\:\frac{y_2+\left(-10\right)}{2}\right)[/tex]

equating

[tex]0=\frac{x_2+\left(-18\right)}{2}[/tex]

[tex]x_2-18=0[/tex]

Add 18 to both sides

[tex]x_2-18+18=0+18[/tex]

[tex]x_2=18[/tex]

also

[tex]5=\frac{y_2+\left(-10\right)}{2}[/tex]

[tex]10=y_2+\left(-10\right)[/tex]

[tex]10=y_2-10[/tex]

[tex]10+10=y_2[/tex]

[tex]10+10=y_2[/tex]

[tex]y_2=20[/tex]

Therefore, the coordinates of the other point are:

(x₂, y₂) = (18, 20)

Hence, option A is correct.

Answer:

(x₂, y₂) = (18, 20)
