how do you factor the polynomial expression 16y4-625x4

The linear equation that passes through the points (14, 15) and (20, 24) crosses the y-axis at y = -6.

A general linear equation can be written as:

y = m*x + b

Where m is the slope and b is the y-intercept.

If the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope can be written as:

m = (y₂ - y₁)/(x₂ - x₁).

In this case the line passes through (14, 15) and (20, 24) so the slope is:

m = (24 - 15)/(20 - 14) = 9/6 = 3/2

y = (3/2)*x + b

To find the y-intercept we can replace the values of one of the points, like (14, 15)

15 = (3/2)*14 + b

15 = 3*7 + b

15 = 21 + b

15 - 21 = b

-6 = b

The y-intercept is -6.

The cutoff score so that only 5% of the population has a higher score is 124.7.

If 5% of the population has a higher score, then the probability of selecting these is 0.05.

Find the z-score that corresponds to the probability in the z-table. (see attached images)

probability = 1 - 0.05 = 0.95

z-score = 1.647

Using the formula for the z-score below, determine the cutoff score.

z-score = (x – μ) / σ

where x = individual data value = cutoff score

μ = mean = 100

σ = standard deviation = 15

1.647 = (x - 100) / 15

1.647(15) = x - 100

x = 24.705 + 100

Answer: slope = [tex]\frac{y}{x}[/tex]

Step-by-step explanation:
Slope means gradient which is given by change in y
                                                                      change in x
on the graph, change in y = 100-0 = 100
                        change in x = 95-45 = 50
so, gradient is 100/50

Aaron has to pay $ 115 when the usage gets over by 3 GBs and
$ (40 + 25x) when the usage gets over by x GBs.

How can one calculate the cost for a multiple of the same entity?
To calculate the cost of a multiple entities when the cost of a single one is given, we linearly multiply a fixed proportion to it to calculate the same.

Given, monthly fixed cost of the smart phone data plan = $ 40
Also, amount charged by the firm for each extra GB used = $ 25
Now, amount charged for three extra GBs = 25*3 = 75
Thus, net total that Aaron has to pay for 9 GBs = 40 + 75 = $ 115
Following similar arguments, amount charged for extra 'x' GBs = 25x
Thus, net total that Aaron has to pay for x GBs = 40 + 25x = $ (40 + 25x)
Therefore, Aaron has to pay $ 115 when the usage gets over by 3 GBs and $ (40 + 25x) when the usage gets over by x GBs.

Answer:

[tex]\dfrac{x-7}{9}[/tex]

which corresponds to choice
C :   [tex]f^{\small -1}(x)\ =\ \frac{1}{9}x\ -\ \frac{7}{9}[/tex]

Step-by-step explanation:

The inverse of a function y = f(x) can be found by interchanging x and y and solving for y

Let y = f(x)

y = 9x + 7

Interchange x and y:

x = 9y + 7

9y + 7 = x  (switch sides)

subtract 7 both sides
→  9y + 7 - 7 = x - 9

→ 9y = x - 9

Divide both sides by 9

a) (2.3 × [tex]$10^4[/tex]) × (1.5 × [tex]$10^{-2}[/tex]) in standard form

The number in standard form is 345

explanation:

The given two multiplication of the numbers is :

(2.3 × [tex]$10^4[/tex]) × (1.5 × [tex]$10^{-2}[/tex])

First we multiply the non exponential terms as shown below

2.3 × 1.5 = 3.45

Now we multiply the exponential terms as shown below

[tex]$10^4[/tex] × [tex]$10^{-2}[/tex] = 100

Now multiplying the exponential and non exponential term we get the number in standard form as shown below

(2.3 × [tex]$10^4[/tex]) × (1.5 × [tex]$10^{-2}[/tex])  in standard form 345

(3.6 × [tex]10^-5[/tex])÷(1.8 × 10²) in standard form 0.0000002

(1.7 × [tex]10^4[/tex]) × (8.5x ×[tex]0^-2[/tex]) in standard form  1.445 × 10³.

3.45 x  100 = 345

Therefore, the number in the standard form is 345

b) (3.6 × [tex]10^-5[/tex])÷(1.8 × 10²) in standard form

The number in standard form is 0.0000002

explanation:

By dividing 3.6 by 1.8 we get “2”, hence the above equation becomes,

(2 × [tex]10^-5[/tex]) /[tex]10^2[/tex]

We know that

[tex]\frac{x^{a} }{x^{b} } = x^{a-b}[/tex]

Therefore the above equation becomes,

2 × [tex]10^-7[/tex]

since the exponent of 10 is negative , therefore 7 zeros are written on the left hand side of the number = 0.0000002

Therefore, the number in the standard form is 0.0000002

c) (8 × [tex]10^-3[/tex]) × (2 × [tex]10^-4[/tex]) in standard form

The number in standard form is 1.6 × [tex]10^-6[/tex]

explanation:

Given the product of scientific notations:

(8 ×  [tex]10^-3[/tex]) ×  (2 ×  [tex]10^-4[/tex])

This can be expressed as:

(8 × 2) ×  ([tex]10^-3[/tex] × [tex]10^-4[/tex])

= 16 ×  [tex]10^-3[/tex]-4

= 16 × [tex]10^-7[/tex]

= 1.6 × [tex]10^1[/tex] × [tex]10^-7[/tex]

= 1.6 × [tex]10^-6[/tex]

Taking into account the definition of a system of linear equations, the first number is x= -14 and the second number y= -13.

A system of linear equations is a set of linear equations (that is, a system of equations in which each equation is of the first degree) in which two or more unknowns are related.

Systems of linear equations have as a solution set all ordered pairs (x, y) that satisfy the equation, where x and y are real numbers. That is, solving a system of equations consists of finding the values of the unknowns, with which, when replaced in the equations, they must give the proposed solution.

In this case, a system of linear equations must be proposed taking into account that

You know:

The system of equations to be solved is

x-y= -1

x+y= -27

It is decided to solve the system of equations using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, isolating the variable "x" from the first equation:

x= -1 +y

Replacing this expression in the second equation:

-1 +y +y= -27

Solving:

y +y= -27 +1

2y= -26

y= (-26)÷2

y= -13

Remembering that x=-1 +y, you get

x= -1 -13

x= -14

Finally, the numbers are -13 and -14.

• x ,is the numbers of CD's produced
