Graph of function f(4x) is a parabolic shape having the x value = {1, 2, 3, 0, -1, -2, -3} and y value = {17, 65, 145, 1, 17, 65, 145}

In mathematics, a function is an expression that describe a relationship between an independent variable and dependent variable in a symbolic form.

we are given, f(x) = x² + 1

let y = f(x)

if we put 4x instead of x we get function of f(4x) = (4x) ²+1

                                                             y =     f(4x) = 16 x² +1

for different input value of x, we get different output value of y

such as x=1, 2, 3, -1, -2, -3 ,0

we get f(4x) = y = 17, 65, 145, 17, 65, 145, 1

if we put the x and y values on the XY coordinate system we will get a parabolic curve.

I hope this answers your Question

Is the ordered pair (6,4) a solution to the inequality y > -1/2 x + 7: D. No, because (6,4) is on the line.

In order to determine if this ordered pair (6, 4) is a true solution based on the given linear inequality, we would have to test the ordered pair by substituting their values into the linear inequality as follows;

For ordered pair (6, 4), we have the following:

y > -1/2x + 7

4 > -1/2 × (6) + 7

4 > -3 + 7

4 > 4 (False).

In this context, we can reasonably infer and logically conclude that the ordered pair (6, 4) is not a true solution for the given linear inequality because it is located on the line.

Step-by-step explanation:

An expression which represents the amount of money the friends still need to buy the microphones include the following: B. 8x² - 7x + 12.

In Mathematics, a quadratic function can be defined as a mathematical expression which defines and represent the relationship that exists between two or more variable on a graph, with a maximum exponent of two (2).

Generally speaking, the standard form of a quadratic function is given by;

ax² + bx + c = 0

Next, we would determine the total amount of money that has been saved by these three friends, Nakobe, Mikah, and Ashton as follows;

Total amount of money saved = x² + x - 12 + 3x + 4

Total amount of money saved = x² + 4x - 8

Now, we can determine the total amount of money that is still needed for the purchase of the microphones:

Total amount of money remaining = 9x² - 3x + 4 - (x² + 4x - 8)

Total amount of money remaining = 9x² - 3x + 4 - x² - 4x + 8

Total amount of money remaining = 8x² - 7x + 12.

An equation is an expression that shows the relationship between two or more numbers and variables.

Area is the amount of space occupied by a two dimensional shape or object.

Let x represent the width and y represent the length

Let us assume that the art project is a rectangle with a length of 12 inches, since the area is 63.6 square inches, hence:

Area = length * width

63.6 = xy

63.6 = x(12)

Answer:

Step-by-step explanation:

Given various quadrilaterals with side lengths marked, you want specific side lengths.

Opposite sides of the parallelogram are the same length, so ...

  5x -18 = 2x +12

  3x = 30 . . . . . . . . . add 18-2x

  x = 10

  DA = 3x -6 = 3·10 -6 = 24

All of the sides of a rhombus are the same length, so ...

  3p -6 = 2p +9

  p = 15 . . . . . . . . . . . add 6-2p

  GS = 2p+9 = 2·15 +9 = 39

The perimeter is the sum of the side lengths.

  46 = (x +8) +(2x +1) +(3x -6) +(4x -7)

  46 = 10x -4

  50 = 10x

  5 = x

Then the side lengths are ...

The length of the shortest side is 9 inches.

Additional comment

The attachment shows a graphical solution to the third problem. The lines y1–y4 are the side lengths as a function of x. The black line finds the value of x that makes the perimeter be 46. That value is 5. The vertical line at x = 5 intersects the other lines at their side length values. The bottom of these is the shortest side length: 9 inches when x=5.

  2000/17 = 117 11/17 miles

Step-by-step explanation:

You want to know the number of miles of a 250-mile trip that are not downhill if 9/17 of the trip is downhill.

The fraction that is not downhill is the difference between the fraction representing the whole trip, and the fraction that is downhill:

  [tex]\dfrac{17}{17}-\dfrac{9}{17}=\dfrac{17-9}{17}=\dfrac{8}{17}[/tex]

That fraction of the total trip miles is ...

  (8/17) · (250 mi) = (8·250)/17 mi = 2000/17 mi = 117 11/17 mi

The number of miles not downhill was 2000/17 or 117 11/17 miles.

Part A: The weekly gross pay with overtime above 40 hours is as follows:

Part B: The gross pay per pay period is as follows:

Gross pay refers to the total earnings before taxable deductions and taxes are removed.

The gross pay per week entails a total paycheck of 52 since there are approximately 52 weeks in a year.

There are 12 months in a year and 26 biweekly payments annually.

Semimonthly payments are made on two set dates in a month, which translates to 24 payments annually.

PART A: Weekly Gross Pay:

1) Hourly rate = $9.90

Total hours worked = 34

Gross pay = $336.60 ($9.90 x 34)

2) Hourly rate = $14.36

Total hours worked = 40

Gross pay = $574.40 ($14.36 x 40)

3) Hourly rate = $12.75

Total hours worked = 45

= ($12.75 x 40 + 5 x $12.75 x 1.5)

= ($510 + $95.625)

Gross pay = $605.625

4) Hourly rate = $13.40

Total hours worked = 51

= ($13.40 x 40 + 11 x $13.40 x 1.5)

= ($536 + 221.10)

Gross pay = $757.10

PART B: Gross Pay Per Pay Period:

5. Annual Salary = $26,805

Pay period = weekly

Number of paychecks = 52

Gross pay per week = $515.48 ($26,805/52)

6. Annual Salary = $49,000

Pay period = monthly

Number of paychecks = 12

Gross pay per month = $4,083.33 ($49,000/12)

7. Annual Salary = $53,278

Pay period = biweekly

Number of paychecks = 26 (52/2)

Gross pay per paycheck = $2,049.15 ($53,278/26)

8. Annual Salary = $32,450

Answer:

x <= 5

Step-by-step explanation:

1st step: Observe the line

The line drawn is vertical.

Hence, it must be in the form x = k , where k is a constant.

2nd step: The line passes through the coordinate (5, 0) along the x axis.

Hence, k is this case is 5.

The shaded region of the graph includes values of x lesser than or equal to 5. (left part of the graph)

Hence, the inequality satisfied by the shaded region is x <= 5. (y can be of any value)

The value of the equation A = ( 2³ x 4 ) / 2 + 2 = 18

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A = 18

Substituting the values in the equation , we get

Answer:

To perform a dilation with a scale factor of 2, we multiply the x and y coordinates of each vertex by 2.

R(1,3) becomes R'(2,6)

S(4,3) becomes S'(8,6)

T(3,1) becomes T'(6,2)

U(2,1) becomes U'(4,2)

To perform a translation of 2 units down, we subtract 2 from the y-coordinates of each vertex.

R'(2,6) becomes E(2,4)

S'(8,6) becomes F(8,4)

T'(6,2) becomes G(6,0)

U'(4,2) becomes H(4,0)

So, the image of trapezoid RSTU after a dilation with a scale factor of 2, followed by a translation of 2 units down is trapezoid EFGH, with vertices E(2,4), F(8,4), G(6,0), and H(4,0).

A measure of central tendency is a descriptive statistics that describes the location of the center of a set of data.

Measure of central tendencies includes the mean, the mode, and the median.

The mean is the average value of the data set

The mode is the value of the most frequent data of the data set

The median is the value at the middle of the dataset, when the data is arranged in order of their increasing values.

The values in the data set are;

56, 60, 60, 60, 62, 64, 64, 66, 66, 90, 95

The mean of the data = (56 + 60 + 60 + 60 + 62 + 64 + 64 + 66 + 66 + 90 + 95) ÷ 11 ≈ 67.[tex]\overline{54}[/tex]
