Select the correct locations on the graph.

Select the lines that represent functions.

Answer:

quadratic functions have a vertex

Answer:

Please check the explanation.

Step-by-step explanation:

We know that the slope-intercept of the line equation is

[tex]y = mx + b[/tex]

where m is the slope and b is the y-intercept

Please note that a linear equation contains no powers of x besides.

For example, the equation of the form

y = 2x+3

has the slope m = 2 and y-intercept b = 3

The graph is shown below.

Let us graph two more functions of the same family by changing the parameter of y-intercept b.

Graphing y = 2x+5

y = 2x + 5

has same slope m = 2. But, the y-intercept b = 5

The graph of y = 2x+5 is attached below.

Graphing y = 2x+7

y = 2x + 7

has same slope m = 2. But, the y-intercept b = 7

The graph of y = 2x+7 is attached below.

Thus, we would have the following graphs of the family of linear functions.

Please notice that all the functions have the same slope m = 2. Thus, all the lines would be parallel.

Thus, from the graph, it is clear that:

The graph is attached below.

Given:

The image of point A under a 90° rotation about the origin is A'(10, -4).

To find:

The coordinates of point A.

Solution:

90° rotation about the origin means the figure is rotated 90° counterclockwise about the origin and the rule of rotation is

[tex](x,y)\to (-y,x)[/tex]

Let the coordinates of A are (a,b).

[tex]A(a,b)\to A'(-b,a)[/tex]

The image of point A under a 90° rotation about the origin is A'(10, -4).

[tex]A'(-b,a)=A'(10,-4)[/tex]

On comparing both sides, we get

[tex]-b=10\Rightarrow b=-10[/tex]

[tex]a=-4[/tex]

Therefore, the coordinates of point A are (-4,-10).

Step-by-step explanation:

Step 1: Define

Point (4, 1.2)

Point (10, 6)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Answer:

[tex]slope = \frac{4}{5} [/tex]

Step-by-step explanation:

slope formula:

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

use the two coordinates given in the graph to find the values

i) (10, 6)

x1 = 10

y1 = 6

ii) (4, 1.2)

x2 = 4

y2 = 1.2

substitute the values into the formula

[tex] \frac{1.2 - 6}{4 - 10} [/tex]

[tex] \frac{ - 4.8}{ - 6} [/tex]

[tex] \frac{4}{5} [/tex]

Step-by-step explanation:

30÷100×640=192

total income =160+192

=352

weekly sales=?(x)

wage=640

so...

x×0.3+160=640

0.3x=640-160

0.3x=480

x=480÷0.3

x=1600

the weekly sales is 1600

The value of 60 milligrams after unit conversion is 0.00006 Kg.

A unit conversion expresses the same property as a different unit of dimension. For case, time can be expressed in twinkles rather of hours, while distance can be converted from long hauls to kilometers, or bases, or any other measure of length.

A conversion factor is an expression for the relationship between units that's used to change the units of a measured volume without changing the value.

We have to convert 60 mg to Kg.

As, 1 Kg = 1000 g

and, 1 gm = 1000 mg

So, 1 mg = 1/ 1, 000, 000 Kg

Then, the conversion is

= 60 / 1, 000, 000

= 6/ 100,000

= 0.00006 Kg

Answer:

We conclude that the range of the function will be:

R = {5, 17, 29}

Step-by-step explanation:

Given

Given the function

f(x) = 6x-1

Given the domain

D = {0, 3, 5}

To Determine:

The range R = ?

We know that range of the function consists of all the y-values for the x-values in the domain of the function.

so substituting the values of x = 0, 3, and 5 in the function to determine the corresponding y-values.

Plug in x = 0

y = 6x-1

y = 6(0) - 1 = 6-1 = 5

Plug in x = 3

y = 6x-1

y = 6(3) - 1 = 18-1 = 17

Plug in x = 5

y = 6x-1

y = 6(5) - 1 = 30-1 = 29

Now, combine all the determined y-values which are 5, 17, and 29.

Therefore, we conclude that the range of the function will be:

R = {5, 17, 29}

Hey there! If you have any questions feel free to let me know in the comments below.

Step 1: Subtract 36 from both sides.

3x = 96 - 36

Step 2: Simplify 96 - 36  to  60.

3x = 60

Step 3: Divide both sides by 3.

x = 60/3

Step 4: Simplify 60/3 to 20.

x = 20

Answer:

Step-by-step explanation:

here you go mate

step 1

Answer:

1500

Step-by-step explanation:

we can write the 4-digit PIN as ABCD

A = factor of 10 so,

A = 1, 2 ,5 (3 possible number or we can write n(A) = 3

B and C are number from 0 - 9 so each have 10 possible number n(B) = 10 and n(C) = 10

D makes the whole number cannbe divide by 2. it means that D must even number 2,4,6,8 or 0. so there are 5 possible number n(D) = 5

so to find how many different sets we just multiply all possible number

n(A) x n(B) x n(C) x n(D)

3 x 10 x 10 x 5 = 1500 different sets

Answer:

X = - 2
