Anyone by chance know how to answer this geometry question I need help so bad

Answer: look at the answwer above this

Step-by-step explanation:

Step-by-step explanation:

Simplify the equation for n.

[tex]23 = - 4n + 15 - 8n + 2[/tex]

[tex]23 = - 12n + 17[/tex]

Subtract 17 from both sides:

[tex]6 = - 12n[/tex]

Divide each side by -12:

[tex] - \frac{1}{2} = n[/tex]

Appropriate Question :

Solve for n :

Solution :

[tex]\qquad{ \dashrightarrow \: { {{ \sf{ 23 = -4n + 15 - 8n + 2 }}}}\:}[/tex]

[tex]\qquad {\dashrightarrow \: { {{ \sf{ 23 = -4n - 8n + 15 + 2 }}}}}\:[/tex]

[tex]\qquad {\dashrightarrow \: { {{ \sf{ 23 = -12n + 17 }}}}}\:[/tex]

[tex]\qquad {\dashrightarrow \: { {{ \sf{ 12 n= 17 - 23 }}}}}\:[/tex]

[tex]\qquad {\dashrightarrow \: { {{ \sf{ 12n = - 6 }}}}}\:[/tex]

[tex]\qquad {\dashrightarrow \: { {{ \sf{ n = - \dfrac{6}{12} }}}}}\:[/tex]

[tex]\qquad {\dashrightarrow \: { {{ \sf{ n = - \dfrac{1}{2} }}}}}\:[/tex]

Answer:

f(-1)=8

Step-by-step explanation:

Just plug in x=-1 into the function:

f(x)=6-2x

y=6-2(-1)

y=6+2

y=8

So f(-1)=8

Answer:

62.8 inches

Step-by-step explanation:

Pizza World sells an extra large pizza that has a radius of 10 inches. What is the circumference of the crust of the extra large pizza? Use 3.14 for πand round answer to the nearest hundredth if necessary.

The shape of a pizza is circular.

The formula for the circumference of a circle is given as:

2πr

Where r = 10 inches

π = 3.14

Circumference of the circle is

= 2 × 3.14 × 10

= 62.8 inches

Therefore, the circumference of the crust of the extra large pizza is 62.8 inches

Answer: x = 15

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    3*x-5-(40)=0

Let's translate the words into mathematical symbols and numbers.

Ten years more than means +10

3/5 of means ×(3/5)

is 28 means = 28

So,

[tex]\frac{3}{5} x+10=28\\(\frac{5}{3}) \frac{3}{5}x=18(\frac{5}{3} )\\x=30[/tex]

Answer:

F(x) = 90 + x

Step-by-step explanation:

Giveb that :

Number of tickets = 6

Cost per ticket = $15

Service fee = $x

Total amount Brenda paid :

Cost of 6 tickets = (15 * 6) = $90 + service charge

F(x) = cost function

F(x) = 90 + x

Answer:

The point C(x, y) after the reflection of the point (x,y) across  the y-axis will become:

C(x, y) → C'(-x, y)

Step-by-step explanation:

We know that the reflection of the point (x,y) across  the y-axis is

the point (-x,y).

In other words, when a shape or object is reflected across the y-axis, the y-coordinate remains the same, but the sign of x becomes the opposite.

For example,

The point C(x, y) after the reflection of the point (x,y) across  the y-axis will become:

C(x, y) → C'(-x, y)

If let suppose the coordinates of the original point C(1, 2), then after the reflection of the point C(1, 2) across  the y-axis, the new coordinates of C would be transformed such as:

C(1, 2) → C'(-1, 2)

Answer:

The fraction of fifth-grade students bought at least one book is calculated as 9/16.

Step-by-step explanation:

From the above question:

Fraction of students that went to the book fair = 9/12

Fraction of students that bought at least one book = 6/8

The fraction of fifth-grade students bought at least one book is calculated as:

6/8 of 9/12

= 6/8 × 9/12

= 3/4 × 3/4

= 9/16

Hence, the fraction of fifth-grade students bought at least one book is calculated as 9/16.

Answer:

12 hours

Step-by-step explanation:

set up a proportion:  2.5 inches / 1 hour  equals  30 inches / x

cross-multiply to get 2.5x = 30

divide 30 by 2.5 to get 12

Answer:

f(x) = 0.5x + 5

Domain: positive whole numbers

Range: f(x) ≥ 5

Step-by-step explanation:

Let's x denote the total number of fruit juice.

This means that if $0.5 for each fruit juice, then the total cost incurred for fruit juice would be $0.5x.

Since she incurred a cost of $5 for 100 cups and $0.5 for each fruit juice, then the total cost, f(x), would be:

f(x) = 0.5x + 5

The domain would be all positive whole numbers (it is restricted to positive whole numbers because a fruit juice can't be "negative" neither can it be "half").

The range is all numbers equal or greater than 5. This is because, even if she does not eventually get fruit juice, she will still incur a cost of 5usd for cups.

Answer:

[tex]m\angle STU=30^\circ[/tex]

Step-by-step explanation:

Angles in a Circle

There are many theorems that relate angles inside and outside a circle.

To solve this question we need to recall the relation of any central angle and a subtended angle by the same arc.

The image below explains this relationship:

Central angle (2x) is twice any inscribed angle (x) subtended by the same arc (marked in red).

The image provided in the question shows an arc US subtended by the inscribed angle SVU and the central angle STU.

If we know the measure of the angle SVU as 15°, then the angle STU must be twice 15°, i.e., 30°.

Answer:

  -15, 3

Step-by-step explanation:

3|x+6| -7 = 20

3|x +6| = 27 . . . . add 7

|x +6| = 9 . . . . . . divide by 3

This resolves to two equations:

  x + 6 = 9

  x = 3 . . . . . subtract 6

and

  x + 6 = -9

  x = -15 . . . . subtract 6

Answer:

Step-by-step explanation:

Find first the constant of variation.

Given: x = 3, y = 4

Find: k = ?

Formula:

[tex]y = \frac{k}{x} [/tex]

Solution:

[tex]y = \frac{k}{x} \\ 4 = \frac{k}{3} \\ 12 = k[/tex]

Then, find the value of y in the third box.

Given: x = 24, k = 12

Find: y = ?

Formula:

[tex]y = \frac{k}{x} [/tex]

Solution:

[tex]y = \frac{k}{x} \\ y = \frac{12}{24} \\ y = \frac{1}{2} \\\boxed{y = 0.5}[/tex]

Answer:

$495

Step-by-step explanation:

The length of the trip is useless information in this question, because you only need cost and members. You divide 2475 by 5 to see how many times it evenly goes into the cost, which brings you your total of $495

Answer:

1090miles/gallon approximately

Step-by-step explanation:

On average a Sedan tank can hold 18.5 gallons.

If it's 75% full, it means it is 18.5 x 0.75 = 13.875 gallons full.

Since the number of miles covered was recorded as 15121 with 75% full gas tank, then to determine mile/gallon can be found by

15121/13.875 ≈ 1090miles/gallon

Answer:

The equation represented by the ordered pair is;

y = 2^(5-x)

Step-by-step explanation:

Here, we want to write the equation represented by the ordered pairs

From what we have in the question, we can see that while the x-values increase in arithmetic progression of 1

The y-values decrease in order of two geometrically

Thus, the equation is;

y = 2^(5-x)
