The relation is a function

Domain = {-2, -1, 0, 1, 2}

Range = {-2, 0, 2}

=================================================

Explanation:

The blue points shown are

(-2,-2)

(-1,0)

(0,2)

(1,0)

(2,-2)

Note how the x values do not repeat themselves. Visually this graph passes the vertical line test. It is impossible to draw a single straight vertical line through more than one blue point at a time. It tells us that any x input leads to exactly one y output.

The relation is a function

The domain is the set of x coordinates of the points

Domain = {-2, -1, 0, 1, 2}

The range is the set of y coordinates of each point

Range = {-2, 0, 2}

Toss out any duplicate items that may occur in the range.

Answer:

The relation is a function.

The domains are 2, 1, 0, -1, -2.

The ranges are -2, 0, 2, 0, -2

Answer:

( 2, -1 )

Step-by-step explanation:

The image of the assumed point Q(2, 3)) under the translation is Q'(-1, 7).

Translation is a type of transformation of geometrical figures. After translation, the original figure is shifted from a place to another place without affecting it's size.

Translation of a point (x, y) indicates that the point is moved x units along the X axis and y units along the Y axis,

Here we have to translate the point Q(2, 3).

Point (x, y) is translated as (x - 3, y + 4).

That is the point (x, y) moves 3 units to the left along the X axis and 4 units upwards along the Y axis.

Q(2, 3) after the translation becomes,

Q'(2 - 3, 3 + 4) = Q'(-1, 7)

Hence the point Q(2, 3) under the translation (x - 3, y + 4) is the point Q'(-1, 7).

315 - 255 = 60

When there is a problem asking how many are left, taken, sold, given, etc. You are usually dealing with subtraction.

Hope that helps and have a great day!

Answer:

The last choice (x+255=315 )

Step-by-step explanation:

This is because we know the total number of tickets is 315 and they have 255 left. So, x + 255 = 315. Because you subtracted __ from 315 to get 255. You can rewrite that as __ + 255 = 315 or  x + 255 = 315

Answer: f-1(x) = 9x + 18.

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y =  x - 2 ( add 2 to both sides )

y + 2 =  x

Multiply through by 9 to clear the fraction

9y + 18 = x

Change y back into terms of x

(x) = 9x + 18

Answer:

Answer: f-1(x) = 9x + 18.

Step-by-step explanation:

Answer: first groups hiking was 6mph, second groups was 4mph.

Step-by-step explanation:

Speed of first group = 6 mph

Speed of second group = 4 mph

If the normal distance between camp A and camp B is x, then the total distance this first group covers will be;

(x + 30) miles

Thus, their speed is;

v1 = (x + 30)/7 mph

Second group left by 1pm and got to camp B by 4pm. This is 3 hours.

Thus;

v2 = ((x + 30)/7) - 2 mph

x = ((x + 30)/7) - 2) × 3

Since;

distance = speed × time

Divide both sides by 3 to get;

x/3 = ((x + 30)/7) - 2)

Multiply through by 21 to get;

7x = 3(x + 30) - 42

7x = 3x + 90 - 42

7x - 3x = 48

4x = 48

x = 48/4

x = 12 miles

Thus, putting 12 for x in V1 equation gives;

v1 = (12 + 30)/7

v1 = 42/7

v1 = 6 mph

Similarly;

v2 = ((12 + 30)/7) - 2

v2 = (42/7) - 2

v2 = 6 - 2

v2 = 4 mph

Move the zeros two places

Answer:

x=25°, y=18°

Step-by-step explanation:

Solved! Here is the explanation. As we have supplementary angles, we have a total of 180° of angles. Angle BXD is a right angle, so 2x+40°=90°. 2x=50°, and then we have x=25°. Now, to figure out y, we have to look at angle BXA. In this case, 5y=90°. y=18°. So, x=25° and y=18°. Hope this explanation helps!

Answer:

Sugar = 0.8 lb

milk = 0.6 lb

Flour = 2.6 lb

Step-by-step explanation:

Firstly, we add the ratios = 3 + 4 + 13 = 20

For milk, we have 3/20 * 4 = 12/20 = 0.6 lb

For sugar l, we have 4/20 * 4 = 16/20 = 0.8 lb

For flour = 13/20 * 4 = 52/20 = 2.6

You will need:

[tex]Milk = 0.6 $ lb\\Sugar = 0.8 $ lb\\Flour = 2.6 $ lb[/tex]

Given:

Milk : Sugar : Flour = 3 : 4 : 13

To find the number of pounds of each ingredient required to produce 4 lb of baking mix, solve as follows:

Amount of each ingredient needed = ratio of each ingredient / total ratio value x 4 lb

Thus:

Total ratio value = [tex]3 + 4 + 13 = 20[/tex]

Amount of milk needed = [tex]\frac{3}{20} \times 4 = 0.6 $ lb[/tex]

Amount of Sugar needed = [tex]\frac{4}{20} \times 4 = 0.8 $ lb[/tex]

Amount of Flour needed = [tex]\frac{13}{20} \times 4 = 2.6 $ lb[/tex]

Therefore, you will need the follow amounts to make 4 lb of baking mix:

[tex]Milk = 0.6 $ lb\\Sugar = 0.8 $ lb\\Flour = 2.6 $ lb[/tex]

Answer:

It’s D

Step-by-step explanation:

The equation of the parallel line is y = x - 3, the correct option is C.

The intersection of the graph of the function with the y-axis gives y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Assume that we've got: y = f(x)

At y-axis, we've got x = 0, so putting it will give us the y-intercept.

Thus, y-intercept of y = f(x) is y = f(0)

We are given that;

x-intercept = 3

Now,

we can find the equation of the line parallel to the given line and passing through the point (3, 0):

The given line has an equation of y = x + 3. This is already in slope-intercept form, so we can see that the slope is 1. The parallel line will have the same slope of 1.

The point that the parallel line passes through is (3, 0). We can use this point and the slope to write the equation of the parallel line in point-slope form:

y - 0 = 1(x - 3)

y = x - 3

Therefore, the slope intercept will be y=x-3

Answer:

The measured side is not shown, so i will answer in a general way.

A cube is a 3-dimensional object with 6 square faces.

You know that all the sides of a square have the same length, then is the same for the cube.

To calculate the volume of a cube, we start with the area of the base.

The base is a square of sidelength L (Suppose that L is the length of the measured side)

The area of the base is:

A = L^2.

To find the volume, we must multiply the area of the base by the height of the fire (because the section of the base does not change).

And the height of the cube is also L.

Then the volume is:

V = L*a = L^3

Answer:

Her rate was faster in the FIRST because her rate was - 19 ft/ minutes in the FIRST PART and - 10ft/minute in the SECOND part

Step-by-step explanation:

Portion 1

Time taken to hike down = 10 minutes

Change in elevation = - 190 ft

Portion 2

Hiked down for further 20 minutes

Change in elevation = - 200ft

During which portion of the hike was her rate of change in elevation greater?

Rate of change in elevation :

Change in elevation / time

Portion 1:

Rate of change in elevation :

Change in elevation / time

- 190 ft / 10 minutes = - 19 ft/minutes

Portion 2:

Rate of change in elevation :

Change in elevation / time

- 200 ft / 20 minutes = - 10 ft/minutes

Her rate was faster in the FIRST because her rate was 19 ft/ minutes in the FIRST PART and 10ft/minute in the SECOND part
