Answer:

1st row = 10 = y

2nd row = 12 = y

3rd row = 18 = y

4th row = 22 = y

Step-by-step explanation:

Given:

y = 4x + 6

since the y-intercept is 6, we know that when the input value(x) is equal to 0, the output value(y) is equal to 6.

so now we plug in the equation for each row,

starting with the first one.

in the first row it says x is equal to 1 so the equation would look like this:

y = 4(1) + 6

simplified the equation to get

y = 4 + 6  = 10

meaning for the first row, y = 10!

since the x value is constant, and only goes up by 1 each row, this means we can just add 4 more each time.

However, I am going to write the equation for each row anyways.

Second row:

y = 4(2) + 6

simplifys into

y = 8 + 6   =  12

y = 12

Third row:

y = 4(3) + 6

simplifys into

y = 12 + 6 = 18

y = 18

Fourth row:

y = 4(4) + 6

simplifys into

y = 16 + 6 = 22

y = 22

So to recap, the answers to each row are...

1st row = 10 = y

2nd row = 12 = y

3rd row = 18 = y

4th row = 22 = y

I hoped this helped and have a good day :D!!!

Answer:

B

Step-by-step explanation:

put both sides under square root.

x^2 + y^2 = 64

sqrt ( x^2 + y^2 ) = sqrt(64)

x + y = 8

r = 8.

[tex]\underline{r^2=x^2+y^2} \\\\\\ x^2+y^2=64\implies r^2=64\implies r=\sqrt{64}\implies r=8[/tex]

Answer:

Step-by-step explanation:

r = 10

h = 6

[tex]Volume =\dfrac{1}{3}\pi r^{2}h\\\\\\ =\dfrac{1}{3}*3.14*10*10*6\\\\=3.14 * 10 * 10 * 2\\\\= 628 \ cubic units[/tex]

Step-by-step explanation:

Answer:

[tex]f(x)=2x-6[/tex]

[tex]f^{-1}(x)=\dfrac{x+6}{2}[/tex]

Step-by-step explanation:

Using slope-intercept form of linear function:  [tex]y = mx + b[/tex]

[tex]\implies f(x)=mx+b[/tex]

[tex]\textsf{if} \ \ f(1) = -4[/tex]

[tex]\implies m + b=-4[/tex]

[tex]\implies b = -4-m[/tex]

Find inverse of slope-intercept form:

swap x and y:  [tex]x = my + b[/tex]

Make y the subject:

[tex]\implies x - b = my[/tex]

[tex]\implies y = \dfrac{x-b}{m}[/tex]

[tex]\implies f^{-1}(x) = \dfrac{x-b}{m}[/tex]

[tex]\textsf{if} \ \ f^{-1}(0) = 3[/tex]

[tex]\implies \dfrac{0-b}{m}=3[/tex]

[tex]\implies b=-3m[/tex]

[tex]\textsf{equation 1:} \ \ b = -4-m[/tex]

[tex]\textsf{equation 2:} \ \ b=-3m[/tex]

Equate the equations and solve for [tex]m[/tex]:

[tex]\implies b=b[/tex]

[tex]\implies -4-m=-3m[/tex]

[tex]\implies -4=-2m[/tex]

[tex]\implies m=2[/tex]

Substitute found value for [tex]m[/tex] into one of the equations and solve for [tex]b[/tex]:

[tex]b = -4-2=-6[/tex]

Substitute found values of [tex]m[/tex] and [tex]b[/tex] into equations for [tex]f(x)[/tex] and [tex]f^{-1}(x)[/tex]:

[tex]f(x)=2x-6[/tex]

[tex]f^{-1}(x)=\dfrac{x+6}{2}[/tex]

Answer:

x - y =9

x^2 + y^2 = 125

2^2 + 11^2 = 125

11-2 = 9

Thus, the two numbers are 2 & 11.

Answer:

1. Paul has mixed up the translation of the ordered pair.

New location: (1, 5)

2. Option C :  E = (3, 2)  F = (8, 4)  G = (5, 7)

Step-by-step explanation:

An ordered pair is a pair of numbers, (x,y) , written in a particular order.

It is often used to represent a point on a coordinate plane.

1.  From inspection of the diagram, the market is located at (3, 8)

Paul's mistake is that he has mixed up the translation of the ordered pair.  He has moved the market 3 to the left and 2 units down instead of the required 2 to the left and 3 units down.

The correct ordered pair for the new location of the market is (1, 5)

2. For each coordinate point (x, y), the first number is the x-coordinate (along the x-axis) and the second number is the y-coordinate (along the y-axis).  

E = (3, 2)

F = (8, 4)

G = (5, 7)

Answer:

[tex]y=\frac{4}{3}x+\frac{4}{3}[/tex]

Step-by-step explanation:

Let [tex](x_1,y_1)\rightarrow(-4,-4)[/tex] and [tex](x_2,y_2)\rightarow(2,4)[/tex]:

Determine slope

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\ \\m=\frac{4-(-4)}{2-(-4)}\\ \\m=\frac{4+4}{2+4}\\ \\m=\frac{8}{6}\\ \\m=\frac{4}{3}[/tex]

Use either coordinate point to find "b", the y-intercept

[tex]y=mx+b\\\\4=\frac{4}{3}(2)+b\\ \\4=\frac{8}{3}+b\\ \\\frac{4}{3}=b[/tex]

Final Equation

[tex]y=\frac{4}{3}x+\frac{4}{3}[/tex]

Hi! I will help you with a smile!

First of all, we have the slope of the line and a point that it passes through.

Let’s write the line’s equation in Point-Slope Form:

y-y1=m(x-x1)

Where

y1 is the y-coordinate of the point, m is the slope of the line, and x1 is the x-coordinate.

In this case, y1=-4, m=-6, and x1=3

Answer:

y = -6x+14

Step-by-step explanation:

m = -6 ,given as x an y (3,-4)

y-(-4) = -6(x-3)

y+4 = -6x+18

then y = -6x+18-4

The area of the triangle can be found by copying the triangle and putting the bases together such that it forms the diagonals of the triangle.

The area of the triangle is half the product of the height of the triangle and the base of the triangle.

As we know that the area of a rectangle is double the area of a triangle,

therefore, in order to calculate the area of a triangle we need to convert it to a rectangle and then divide the area of the rectangle by 2.

Also, we know that the diagonal of a rectangle divides it into two equal triangles, therefore, we will put the triangle along the diagonal of the base.

Thus, to find the area of the triangle we will copy the triangle and put the base of the together such that it forms the diagonals of the triangle.

Since the triangles are put on each other along the base, therefore, the height(h) of the triangle will be the length of the rectangle, and the breadth of the triangle will be equal to the base of the triangle(b).

Answer:

total area = 132 units²

Step-by-step explanation:

Area of largest rectangle = 4 x 15 = 60 units²

Area of smallest rectangle = 4 x 6 = 24 units²

Area of largest triangle = 1/2 x (15 - 6) x (4 + 4) = 36 units²

Area of smallest triangle = 1/2 x 6 x 4 = 12 units²

Total area of the figure = sum of areas of 2 rectangles and 2 triangles

⇒ area = 60 + 24 + 36 + 12 = 132 units²

Excel formulas are expressions used to perform computation.

From the complete question, cell B21 represents base work hour

So, we start by checking if the work hour in cell D5 is less than the base work hour in cell B21

If yes, the work hour remains D5; otherwise the work hour is cell B21

The work hour is then multiplied by the rate in cell C5

Hence, the Excel formula to enter in cell E5 is =IF(D5<$B$21,D5,$B$21) *

Here, we start by checking if the work hour in cell D5 is greater than the base work hour in cell B21

If yes, the overtime hour the difference between D5 and B21; otherwise the overtime hour and pay is 0

The over time hour if there is, is then multiplied by the rates in cells C5 and B22

Hence, the Excel formula to enter in cell E5 is =IF(D5>$B$21,(D5-$B$21) * C5 * $B$22, 0)

Functions can be modeled by equations, tables and graphs

From the question, we have the following ordered pairs

(x,y) = (0,1) and (4,2)

The function is a linear function.

So, we start by calculating the slope (m) using:

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

Substitute known values

[tex]m = \frac{2 - 1}{4 - 0}[/tex]

[tex]m = \frac{1}{4}[/tex]

The equation is then calculated as:

[tex]y = m(x -x_1) +y_1[/tex]

This gives

[tex]y = \frac 14(x -0) +1[/tex]

[tex]y = \frac 14x +1[/tex]

The domain of the above function is the set of whole numbers
