The three methods to solve a 3 variable linear system of equations are interchanging the order of any two equations, multiplying both sides of an equation by a non-zero constant, add a non-zero multiple of one eqn to another eqn.

In order to solve any system of equations in three variables, known as three-by-three systems, the primary purpose is to eliminate one variable at a time to achieve back-substitution. A solution to a system of three equations in three variables (x,y,z), is known as an ordered triple.

Step 1. Choose any pair of equations and solve for one variable.

Step 2. Choose another pair of equations and determine the same variable.

Step 3. You have developed a system of two equations in two unknowns. Solve the resulting two-by-two system.

Step 4. Back-substitute the known variables into any one of the original equations and solve for the missing variable.

The midpoint formula is used to calculate elasticity because it overcomes the limitations of the traditional method.

The old point-slope method has significant drawbacks that are overcome by the midpoint formula, which determines the elasticity of demand. The elasticity of demand refers to how sensitively a good's quantity desired is to a price shift. Inelastic goods are those in which a little price shift causes a large change in quantity demanded, while elastic goods are those in which a small drop causes a small change in quantity demanded.

The conventional point-slope formula for elasticity employs the change in quantity and price at a particular point, which might be deceptive in some circumstances. Contrarily, the midpoint formula determines the elasticity of demand by averaging the quantity and price at the beginning and end and utilising the percentage change in both.

The Function after reflection over x-axis is D) g(x) = -4IxI.

What is Function?

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. An expression, rule, or law in mathematics that establishes the relationship between an independent variable and a dependent variable (the dependent variable).

Here The graphs of g may be obtained from the graph of f by shifting up c units. The graph moves downward if we take c out of f(x). Let h(x) = f(x)-c shifting downward c units yields this graph of h from the graph of f.

Now given function f(x)= 4IxI.

It is stated that its graph of  is obtained by reflecting a graph of f(x)= 4IxI over the x-axis.

When a figure is reflected across the x-axis, the rule for reflection is

(x,y)=>(x,-y)

Then g(x)=-f(x),

=> g(x) = -(4IxI)

=> g(x) = -4IxI

Hence the correct option is D)g(x) = -4IxI.

What is Pythagorean theorem?

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in

Euclidean

geometry.

According to this rule, the areas of the squares on the other two sides add up to the area of the square whose side is the hypotenuse, or the side across from the right angle.

This theorem can be expressed as the Pythagorean equation, which is an equation connecting the lengths of the sides a, b, and the

hypotenuse

c.

There are several ways to generalize the theorem, including to higher-dimensional spaces, non-Euclidean spaces, objects other than right triangles, and even things that are not triangles at all but n-dimensional solids.

Answer:

The effective tax rate for a taxable income of $145,690 would be 24.39%.

Step-by-step explanation:

To find the effective tax rate, you need to calculate the total amount of tax paid on the taxable income, and then divide that amount by the taxable income, and multiply by 100 to express it as a percentage.

We can see from the marginal tax rate chart that for a taxable income of $145,690, the marginal tax rate is 24%. This means that the last dollar earned falls in the 24% tax bracket.

We can calculate this in the following steps:

Determine the taxable income in each tax bracket:

$10,276 - $41,175: $41,175 - $10,276 = $30,899

$41,176 - $89,075: $89,075 - $41,176 = $47,899

$89,076 - $170,050: $145,690 - $89,076 = $56,614

Calculate the taxes owed in each tax bracket:

$10,276 - $41,175: $30,899 x 12% = $3,707.88

$41,176 - $89,075: $47,899 x 22% = $10,526.78

$89,076 - $170,050: $56,614 x 24% = $13,547.36

Add up the taxes owed in each bracket to find the total taxes: $3,707.88 + $10,526.78 + $13,547.36 = $27,782.02

Divide the total taxes by the taxable income and multiply by 100 to find the effective tax rate: $27,782.02 / $145,690 x 100 = 19.02%

The effective tax rate for a taxable income of $145,690 would be 19.02%.

It's worth to mention that this is a rough estimate and The final tax calculation would be provided by a tax preparer or software and it would take into account many deductions, credits and any other tax benefits that would affect the final calculation.

The average rate of change for the interval from x = 5 to x = 6 can be calculated by taking the derivative of the quadratic function and evaluating it at the midpoint of the interval (x = 5.5).

Given that the vertex of the function is at (1, 0), the equation of the quadratic function is in the form of:

f(x) = a(x-1)^2 +0

The derivative of the function is:

f'(x) = 2ax - 2a

We know that the vertex of the function is at (1,0), which means that the value of a is 0.

So the derivative of the function is 0.

Therefore the average rate of change for the interval from x = 5 to x = 6 is 0.

Answer: The study indicated that residents of Springtown wasted 7,622 gallons of water this year, which is 85% more than they wasted last year. To find out how many gallons of water the city's residents wasted last year, we need to find out what 85% of 7,622 gallons is and then subtract that amount from the total amount wasted this year.

85% of 7,622 gallons is (85/100) * 7,622 = 6,465.7 gallons

So, if residents of Springtown wasted 7,622 gallons of water this year, which is 85% more than they wasted last year, then they wasted 7,622 - 6,465.7 = 1,156.3 gallons of water last year.

Step-by-step explanation:

Answer:

x = 4120 gallons wasted last year

Step-by-step explanation:

Let x be the amount of water wasted by the residents of Springtown "last year."

They wasted 85% more this year.  This would mean that x*(1+ 0.85) = 7622 gallons.  [The "(1+0.85)" represents the decimal equivalent to "85% more."

x*(1+ 0.85) = 7622

1.85x = 7622

x = 4120 gallons wasted last year

Check:

Is 7622 85% more than 4120?

(7622-4120)=3502
