How to multiply easily big Numbers

Answer:

The answer is -1 or -3

Step-by-step explanation:

You woud use the quadritic formula

[tex]x=\frac{ -b+- \sqrt{b^{2} -4ac} \\}{2a}[/tex]

[tex]x=\frac{-24 +- \sqrt{576-432} }{12} \\[/tex]

[tex]x=\frac{-24+- \sqrt{144} }{12}[/tex]

[tex]x=\frac{-24+12}{12}\\\\x=\frac{-12}{12} \\x = -1[/tex]

or

[tex]x=\frac{-24-12}{12} \\\\x= \frac{-36}{12} \\\\x= -3[/tex]

First, we need to define rational numbers

Rational numbers are numbers that can be express as a quotient or fraction

From the question given, The square root of 16 is 4, this can be express as 4/1

Hence, it is a rational number

Therefore the correct option is A

Answer

Step-by-step Explanation

7 = 2x - 5

12 = 2x

6 = x

The movement from the first step to the second step involves adding 5 to both sides.

7 = 2x - 5

7 + 5 = 2x - 5 + 5

12 = 2x

Adding 5 to both sides, is what the addition property of equality means.

Then, the movement from the second step to the third step involves dividing both sides by 2.

To find the total plus tax she must multiply the price of the pair of pants and 108.75% ≈ 1.0875.

Given:

Alexa went shopping for a new pair of pants.

Sales tax where she lives is 8.75%.

Let x be the price of pants.

Total plus tax = prices of pair of pants *  1.0875.

= x * 1.0875

= 1.0875x.

Therefore to find the total plus tax she must multiply the price of the pair of pants and 108.75% ≈ 1.0875.

The function is odd because f(–x) = –f(x).

What is a function?

A function is a special form of relation where each input has exactly one output. In other words, for each input value, the function returns exactly one value. A relation rather than a function is depicted in the above graph because one is mapped to two different values. However, if one were instead mapped to a single value, the relationship described above would change into a function. Furthermore, output values could match input values exactly.

Odd function means f(-x) = -f(x)

and Even function means f(-x) = f(x)

Here the given function f(x) = 4[tex]x^{5}[/tex]

Put, x = -x

We have f(-x) = 4 ([tex](-x^){5}[/tex])

5 is an odd number so we will get a negative value. So f(-x) = -f(x)

Hence, The function is odd because f(–x) = –f(x).

Answer:

the graph given has a greater unit rate

Step-by-step explanation:

basically, you have to compare the gradients of both the graphs

one graph's equation is given i.e y=47/2 where 47/2 is the gradient/slope now find the gradient/slope of the given graph:

slope = x2-x1/y2-y1

chose any two coordinates on the graph and input them in the equation

I chose (2,94) and (4,188)

inputting them in the equation:

188-94/4-2

=94/2

now see which one is greater 47/2 or 94/2

94/2 is greater than 47/2 so it has a greater unit rate

Answer:

The sequence of transformation that can be performed on quadrilateral ABCD to show that it is congruent to quadrilateral GHIJ is a 90 degrees counterclockwise rotation about point A followed by reflection across the y-axis and a translation of 20 units down.

Explanation:

The sequence of transformations are described in the following figure:

Therefore, the first transformation is a rotation of 90 degrees counterclockwise about point A. After that transformation, we get the figure A'B'C'D'

Then, we reflect the figure across the y axis, so we get A''B''C''D''

Finally, we translate the figure 20 units down to get GHIJ

So, the answers are:

The sequence of transformation that can be performed on quadrilateral ABCD to show that it is congruent to quadrilateral GHIJ is a 90 degrees counterclockwise rotation about point A followed by reflection across the y-axis and a translation of 20 units down.

EXPLANATION

We want to find the equation for the function graphed.

We see that the function passes through -1 and 4 on the x-axis and 1 is the y-intercept.

These are called the roots of the function. The roots are the x values where the function equals 0.

We can find the function by applying the roots:

where x1 and x2 are the roots.

a = leading coefficient

Therefore, we have that:

Expand the brackets:

Now, we have to find a.

To do that, we use the y-intercept of the function (0, 1). The y-intercept is the value of the function when x is 0.

Therefore, when x = 0, y = 1:

Now, substitute the value of a into the function obtained earlier.

That is the equation of the function graphed.

The slope intercept form of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept. The given equation can be written in terms of slope in y = 0.6x + 5.

A straight line can be written in the form of equation as, y = mx + c.

Two straight lines intersect each other only at one point.

When two straight lines are parallel to each other the angle between them is zero.

Given that,

The equation of the line is 12x - 20y = -100

In order to write the given equation in slope-intercept form, write the given equation in terms of y as,

12x - 20y = -100

=> 20y = 12x + 100

=> y = 12 / 20x + 100 / 20

=> y = 0.6x + 5

Where slope is 0.6 and y-intercepts is 5.

Hence, the slope-intercept form of the given equation is  y = 0.6x + 5.

Step-by-step explanation:

The slope of the line shown is 0.5 .

How to find the slope of a given line?
For a line passing through the points (x₁, y₁) and (x₂, y₂), the slope for the same can be defined with the mathematical value of m i.e.,
m = (y₂ - y₁)/(x₂ - x₁)

Given, the line in picture passes through the points (0, -3) and (6, 0).
Following the formula established in the literature above, the given line has slope as m, which is:
m = (y₂ - y₁)/(x₂ - x₁) = (0 - (-3))/(6 - 0) = 3/6 = 0.5

The three types of quadratic functions are as follows: We can quickly find the y-intercept using the standard form. We can quickly locate the vertex in vertex form, and we can quickly determine the roots/zeros in factored form.

The three forms of quadratics are the standard form, the vertex form, and factored form. Each of them reveals a specific part of the quadratic.

A quadratic has the following standard form:

A quadratic in standard form can immediately convey only two details: (1) the leading coefficient a and (2) the y-intercept. The leading coefficient a determines whether the parabola curves upwards or downwards. The y-intercept will be given by the constant c.

Vertex Form: The vertex form of a quadratic is:

There are also two details that can be conveyed by a quadratic in vertex form: (1) the vertex, and (2) the leading coefficient. The leading coefficient is given by a. This tells us the orientation of the parabola. The vertex is given by (h, k). Hence, in my opinion, vertex form is the best form of a quadratic since it immediately reveals the vertex, the most important aspect of a quadratic.

Factored Form: The factored form of a quadratic is:

Where p and q are the zeros/roots/solutions of the quadratic. Factored form gives us two details about the quadratic: (1) the leading coefficient, and (2) the zeros. The zeros tell us when the parabola crosses the x-axis, which can assist in graphing.

Therefore,

Each form of a quadratic equation has its own benefits.

The standard form allows us to find the y-intercept.

The vertex form allows us to quickly locate the vertex.

The factored form allows us to quickly determine the roots/zeros.

We have to blend two mixtures of ethanol (E7 and E10) to make an E9 mixture.

We know that the amount of E10 mixture is 4000 gal.

Let x be the amount of E7 mixture.

As we have x gallons of E7 and 4000 gallons of E10, the volume of the E9 mixture will be (x+4000).

The volume of ethanol in the E7 mixture will be 0.07*x gallons.

The volume of ethanol in the E10 mixture is 0.1*4000 = 400 gallons.

The volume of ethanol in the E9 mixture will be 0.09*(x+4000) gallons.

As the sum of the ethanol volume in the E7 and E10 mixtures has to be equal to the ethanol in the E9 mixture, we can write:

We can use this equation to solve for x:

Then, the volume of the E7 mixture has to be 2000 gallons.

Answer: 2000 gallons of E7 mixture.
