The sales tax of his purchase if he lives in Florida where the sales tax rate is 6 percent is $67.92

The word "percent" comes from the Latin per centum, which means "hundred" or "by the hundredth." The symbol for "percent" emerged gradually from the Italian expression per cento, which means "for a hundred." The "per" was frequently shortened as "p." and eventually vanished. The "cento" symbol was simplified to two circles divided by a horizontal line, from which the contemporary "%" symbol was formed.

The abbreviation "pct.", "pct," and sometimes "pc" are also used. A % is a dimensionless (pure) number with no unit of measurement.

Given,

Total purchase=$878

For two tables,

2×127=254

Total=878+254

=1132

6% of 1132 is,

(6/100)×1132

The technological innovation could help solve an environmental issue that is likely to threaten Australia in the future is D. Using electric cars could help lessen droughts.

Streamflows decrease, water levels in lakes and reservoirs fall, and the depth to water in wells increases when rainfall is less than normal for a period of weeks to years. If the dry weather continues and water supply issues arise, the dry period may turn into a drought.

For the first time since 2017, Australia ended 2021 in an unusual climatic state, with no region in this famously vast, mostly brown land officially declared to be in drought. It should be noted that the country has drought challenges and electric cars could help reduce the water used.

The equation of the line parallel to x - y = 3 and passes through pint (2,-4) is y = x - 6.

The equation of line is expressed as;

y = mx + b

The point-slope formula is expressed as;

y - y₁ = m( x - x₁ )

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

Given the data in the question;

Point: (2,-4)

First, reorder the given equation in slope-intercept form and determine the slope.

x - y = 3

x = 3 + y

3 + y = x

y = x - 3

Hence,

The slope m = 1

To find the line parallel to the equation, the slope must be equal.

Find the line using point-slope formula.

y - y₁ = m( x - x₁ )

Plug in slope m = 1 and point: (2,-4)

y - ( -4 ) = (1)( x - 2 )

Simplify and convert to slope intercept form.

y + 4 = x - 2

y = x - 2 - 4

y = x - 6

Therefore, the equation of line is y = x - 6.

It is important to note that place values can be defined as the value that's represented by a digit based on the position that it takes. In mathematics, place value refers to the position or location of a digit in a number.

Each digit has a specific place in a number. The position of each digit will be expanded when we represent the number in general form. Those positions begin with a unit place, also known as one's position.

In this case, we want to know the value of 3 in 5.53. It should be noted that the first 5 is 5 ones, the second 5 is 5 tenths and the 3 is 3 hundredths.

What is the value of 3 in 5.53?

The degree of the polynomial is 5, and the end behavior is:

as x → ∞, f(x) → -∞

as x → -∞, f(x) → ∞

For any given polynomial, we define the degree as the largest exponent on the polynomial.

On this case we have:

f(x) = 2x^3 - 3x^5 - x^2 + 1

We can see that the largest exponent is 5, so the degree is 5.

Now, for the ending behavior.

If we have an odd degree (like in this case) we will have opposite ending behaviors in both ends of the domain.

If the leading coefficient is negative (like in this case, it is -3) then the end behavior will be:

as x → ∞, f(x) → -∞

as x → -∞, f(x) → ∞

The extrema of the quadratic equation is at the vertex, and it is a minimum at:

y = -1.75

Here we have the following quadratic equation:

y = 3x^2 - x - 2

We can see that the leading coefficient (the coefficient in the term with the largest exponent) is positive, this means that the parabola opens upwards.

This means that the vertex of the quadratic equation will be a minimum.

Remember that for a quadratic equation:

y = a*x^2 + b*x + c

The vertex is at:

x = -b/2a

So for our quadratic, the vertex is at:

x = -1/(2*3) = -1/6

Evaluating the quadratic equation there we get:

y = 3*(-1/6)^2 - (-1/6) - 2

y = -1.75

That is the minimum of the quadratic.

The equation of the line, in slope-intercept form, that passes through

(4, 2) and (-2, -3) is y = 5/6 x - 4/3.

What is slope-intercept form?

The meaning of slope-intercept form is the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.

Using two points and slope-intercept form we can find the equation of the line.

According to the given question:

The formula to find the slope of two points (x₁, y₁) and (x₂, y₂) is

m = (y₂ - y₁) / (x₂ - x₁)

The points given are (4, 2) and (-2, -3)

m = (-3 - 2) / (-2 - 4)

m = -5/ -6

m = 5/6

Now using the slope and the point (4, 2) the y intercept is

y = mx + b

2 = 5/6 (4) + b

2 = 10/3 + b

By further calculation,

b = 2 - 10/3

Taking LCM

b = (6 - 10)/3 = -4/3

By writing the equation in slope intercept form

y = mx + b

y = 5/6x - 4/3

Therefore, the equation of the line in slope intercept form is

y = 5/6 x - 4/3.

Step-by-step explanation:

Solving quadratic equation and linear equation:

2x² + y² = 19 -----------------(I)

x + 3y = 0 -----------------(II)

         x = -3y --------------(III)

Substitute x = -3y in equation (I) and we can find the value of y.

2(-3y)² + y² = 19

2*9y² + y²  = 19

  18y² + y² = 19

Combine like terms,

          19y² = 19

             y² = 19 ÷ 19

              y² = 1

              y = √1

              y = ±1

Substitute y = ±1 in equation (III) and find the value of x.

When y = 1,

              x = -3*1

              x = -3

When y = -1,

               x = -3*(-1)

Please Mark Me Brainliest!!!

(I'm in 5th Grade Honors but I learn MS)

Answer:

All the answer are A

Step-by-step explanation:

Area = length times width

405 = x15  Divide both sides by 15

27 = x

For the x intercept  Let y = o and solve for x

5x - 3y -15 = 0

5x - 3(0) -15 = 0

5x -15 = 0  Add 15 to both sides of the equation

5x = 15  Divide both sides by 5

x = 3

The x intercept is (3,0)

For the y intercept Let x = 0 and sole for y

5x -3y -15 = 0

-3y -15 = 0  Add 15 to both sides of the equation

-3y = 15  Divide both sides by -3

y = -5

The y intercept is (0,-5)

4x + 3y + 7x - y  Combine the like terms

(4x + 7x) = (3y -y)

11x + 2y
