The equation y = 2x - 8, best describes the relationship between the corresponding values of x and y shown in the table.

A linear equation is defined as an equation in which the highest power of the variable is always one.

The table is given in the question, as follows:

x : -2    0    1     4

y : -12  -6   -3    6

Option C,  y = 3x - 6, best describes the relationship between the corresponding values of x and y shown in the table. This can be seen by plugging in the x values from the table into the equation and observing that it yields the corresponding y values.

So substitute the values of x = 4 and  y = 6 in the equation  y = 3x - 6, and we get

6 = 3(4) - 6

6 = 12 - 6

6 = 6

Hence, the correct answer would be option (C).

The state withholding tax for the unmarried person Mary Smith is 6.76.

When paying rent, commissions, or fees for professional services at rates specified by current tax laws, the taxpayer is required to withhold tax, which is also known as retention tax.

A tax determined using the tables or computation methods prescribed by the Secretary must be deducted and withheld from all wages paid by an employer, unless otherwise specified in this section.

Withholding taxes are paid by employers to the IRS on behalf of the employee. The amount collected is applied as a credit to the employee's yearly income tax liability. If too much money is withheld, the employee gets a tax refund; if not enough, the employee might have to pay the IRS.

Finance amount: The amount you can finance for a new car with a monthly payment of $240, for 60 months (5 years), depends on several factors, including the loan interest rate, the down payment, and the value of the car.

Estimated percentage rate: The interest rate for a new car loan with a credit score between 601-660 typically ranges from 5% to 10%.

Amount of interest you will pay for the loan: The amount of interest you will pay for the loan can be calculated by multiplying the loan amount by the interest rate and the number of months.

Answer:

14,35,42,63,77

Step-by-step explanation:

Actually how to get the output you follow the rule;

n×7

the first will be;2×7=14

the second will be; 5×7=35

the third will be; 6×7=42

the forth will be; 9×7=63

the fifth will be; 11×7=77

Just enter each value of x into the formula f(x) = x - 4. For example, f(x) = 2 - 4 = -2 when x = 2.

A general rule is that the algebraic expression should take any of the following forms: addition, subtraction, multiplication, and division. to ascertain x's value.

Finding the value of f(x) =... or y =... that corresponds to a given value of x is the definition of function evaluation. Simply swap out all instances of x with the value that has been allocated to x to do this. For instance, if f(4) is to be evaluated, then x has been given the value of 4.

Separate the variable. In this instance, you transfer the constant term across the equal sign by doing the reverse operation on both sides and adding 1 to isolate the variable term. Isolate the variable further, then simplify.

Given,

f(x)=x-4

⇒ when x = -2,

⇒ f(x) = -2 -4 = -6

When x = -1,

⇒ f(x) = -1 -4 = -5

When x = 0

⇒ f(x) = 0 -4 = - 4

When x = 1

⇒ f(x) = 1 -4 = -3

When x = 2

⇒ f(x) = 2 -4 = - 2

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the population of the town X in 2020 be A

Let the percentage of increase be represented as r

Now , the equation will be

The initial population of Town X be A = 220,000

The increased population in 10 years be B = 252,000

So , the percentage change = [ ( B - A ) / A ] x 100

Substituting the values in the equation , we get

The percentage change r = [ ( 252,000 - 220,000 ) / 220,000 ] x 100

On simplifying the equation , we get

The percentage change r = [ 32,000/220,000 ] x 100

The percentage change r = 0.1454545 x 100

The percentage change r = 14.545 %

Now , the population of the town X in 2020 = ( 14.545 + 100 )% x increased population in 10 years

On simplifying the equation , we get

Step-by-step explanation:

The right angle is equal to 90 degrees

Therefore (5x - 8) + (4x + 35) is equal to 90 degrees

5x - 8 + 4x + 35 = 90

5x + 4x + 35 - 8 = 90

9x + 27 = 90

     - 27    -27 (subtract 27 from both sides)

9x = 90 - 27

9x/9 = 63/9 (divide both sides by 9)

x = 7

Given that, a random list of 100 numbers and the assignations 0-4 to represent girls and 5-9 to represent boys,

a) Based on the results of the simulation, what is the experimental probability that a group will include only boys?

Answer :- 6 of the numbers simulate groups of all boys: 7579, 6577, 5697, 9675, 5656, 6658. So, the experimental probability of a group being all boys is 6/100 = 0.06

b) Based on the results of the simulation, what is the experimental probability that a group will not contain four boys?

Answer :- The other 94 groups do not include only boys.

The probability that the group will not contain four boys is

1 -6/100 = 94/100 = 0.94

c) Based on the results of the simulation, if 224 groups are formed, about how many of them would you expect to contain all girls?

Answer :- 9 of the groups contain all girls. Based on these results, we would expect,

9/100 × 224 ≈ 20

The slope of the given line ( 2 / x ) + ( 3 / y ) = 0 which is calculated by solving the equation is equal to ( - 3 / 2).

A line's slope is defined as the ratio of the change in y coordinate to the change in x coordinate.

The net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx.

Hence, the expression for the change in y-coordinate with respect to the change in x-coordinate is,

m = y/x = y/x = change in y/change in x

where "m" represents a line's slope.

Furthermore, the slope of the line can be shown as

tan θ = Δy/Δx

So, tan θ to be the slope of a line.

As given in the question,

Given equation of the line is equal to ( 2 / x ) + ( 3 / y ) = 0

Simplify the given equation to get the slope intercept form :

( 2 / x ) + ( 3 / y ) = 0

⇒ ( 2 / x ) = - ( 3 / y )

⇒ 2y = -3x

⇒ y = ( - 3 / 2 ) x + 0  __(1)

Standard slope intercept form of the line is given by :

y = mx + c  __(2)

Where m is the slope of the line

Compare (1) and (2) to get the slope of the line we get,

Slope of the line 'm' = ( - 3 / 2 )

Therefore, the slope of the given line by simplify the equation

( 2 / x ) + ( 3 / y ) = 0 in slope intercept form is equal to ( - 3/2).
