Answer:

Inverse of -5-9x/x-6

Step-by-step explanation:

Steps:

1: Interchange the variables x and y.      

x=6y-5/y+9

2: Solve x = 6y-5/y+9 for y

3: Multiply both sides by y+9

4: Simplify and Expand

5: Subtract 9x from both sides.

6: Simplify and Subtract y from both sides then Simplify again

7: Divide both sides by x-6

Answer: Inverse of -5-9x/x-6

Hope this helps.

Answer:

To find the inverse, interchange the variables and solve for  

y .

f ^− 1 ( x )  =  − 9  −  x  −  √ (x ^2  −  18 x  +  201 )) /(12 ) , (− 9  −  x  +  √ (x ^2  −  18 x  +  201))  / (12 )

Answer:

part a: $33.50

part b: $24.50

Step-by-step explanation:

add up all of the costs of the books so 19.50 + 8.50 + 5.50 = $33.50

next just subtract 9 dollars from 33.50 so 33.50 - 9 = $24.5 more he needs.

Answer:

Step 3

Step-by-step explanation:

She made her first mistake in Step 3.

This is because 4/7 is actually less than 5/3.

Step 1 and 2 are mathematically accurate.

1/2 is less than 1.

So, since 4/7 is only greater than 1/2 and not greater than 1 as compared to 5/3 which is actually greater than 1, she should have concluded that 4/7 is less than 5/3.

Therefore, Step 3 contains the mistake.

Answer:

The rate of change at which the water level rise is 13/6 cm/minute.The slope of the line is 13/6.The value of y is 23, (12,23).

Step-by-step explanation:

In the question the water rises 13 cm every 6minutes. Taking x to represent the time in minutes and y to represent the rise in cm then, find the rise y in time x as;

6 minutes=13 cm

1 minute=?---------------------perform cross multiplication

(1*13)/6=13/6

Hence in 1 minute, the rise is 13/6 cm

Thus in 12 minutes, the rise will be ;

12 * 13/6 = 2*13= 26 cm

(x,y) will be (12,26)

Finding the slope of the line using point (6,13) and (x,y)

The rate of change at which the water level rises equals the slope of the line.This is the justification.

Answer: 810

Step-by-step explanation:

first lets take down the information we were given,

height (h) of the pyramid should be 12 - 9 = 3

base (a) = 9

So we calculate the volume of a square pyramid

V = a²h/3

V = (9² × 3) / 3

v = (81 × 3) / 3

V = 81

now we calculate the volume of the cube using the formula

V = a³

V = 9³

V = 729

NOW to get the volume of the entire figure

we say

volume of square pyramid + volume of cube

81 + 729 = 810

Answer:

just read through this document

The cost of a baseball ticket is $26.64 and the cost of a football ticket is $74.99.

If a family of 5 would like to attend one game during the football season and one during the baseball season,

The cost of a baseball ticket is $133.2 and the cost of a football ticket is $374.95.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

For the 2009 Major League Baseball and National Football League seasons, based on average ticket prices,

Three baseball tickets and two football tickets would have cost $229.90, while two baseball tickets and one football ticket would have cost $128.27.

Let x represents the cost of one baseball ticket and y represents the cost of a football ticket.

Then,

3x + 2y = 229.90

2x + y = 128.27.

The solution of the system of the equation is the intersection point of the line.

The solution = (26.64, 74.99)

The cost of a baseball ticket is $26.64 and the cost of a football ticket is $74.99.

If a family of 5 would like to attend one game during the football season and one during the baseball season,

the cost of a baseball ticket is $26.64x 5 = $133.2 and the cost of a football ticket is $74.99x5 = $374.95.

Therefore, all the required value is given above.

Answer:

Profits increase until the price of the shoes reaches $22.

There are more prices with positive revenues than positive profits.

Step-by-step explanation:

In the picture attached, the problem is shown.

The first sentence is true because the profit curve has a maximum at $22.

The second sentence is true because the profit is computed as follows:

profit = revenue - cost

and cost decreases as the price increase; therefore, there are positive revenues with negatives profits.

The  two sentences which correctly interpret the graph include:

This is defined as a pictorial representation of numbers or variables in an organized manner.

The profit curve has a maximum at $22 which makes statement 1 correct while from the graph we can also deduce that there are more prices with positive revenues.

Answer:

A line parallel to the y-axis has no defined slope, and a line parallel to the x-axis has slope of zero.

Step-by-step explanation:

Lines parallel to the y-axis are vertical and are undefined as they don't technically have a gradient.

lines parallel to the x-axis are horizontal and have a gradient of 0 since there is no positive or negative angle, it's just straight.

Answer:

x =28

Step-by-step explanation:

We have similar triangles, so we can use ratios

Answer:

d

Step-by-step explanation:

The sum to n terms of a geometric sequence is

[tex]S_{n}[/tex] = [tex]\frac{a(r^{n}-1) }{r-1}[/tex]

where a is the first term and r the common ratio

Here a = 3 and r = 12 ÷ 3 = 4 , thus

[tex]S_{8}[/tex] = [tex]\frac{3(4^{8}-1) }{4-1}[/tex]
