Answer:

7m² - 11m - 2

Step-by-step explanation:

(4m² - m + 2) - (-3m² + 10m + 4)

4m² + 3m² - m - 10m + 2 - 4

7m² - 11m - 2

Answer:

C. No, because it fails the vertical line test.

Step-by-step explanation:

The vertical line test a method used to check if a graph represents a function.

if you move a vertical line along the graph the line always crosses one point at a time however if the line touches two points at the same time then it is not a function .

The graph fails the vertical line test, it does not represent a function

C. No, because it fails the vertical line test

The vertical line test is a graphical test used to determine if a graph represents a function.

According to the vertical line test, if any vertical line intersects the graph in more than one point, then the graph does not represent a function.

In the graph provided, we see that there a vertical line will intersect the graph in more than one point.

Since the graph fails the vertical line test, it does not represent a function. Therefore, option C is the correct answer: "No, because it fails the vertical line test."

Answer:

x=1

or

[tex]x=-\frac{1}{40}[/tex]

Step-by-step explanation:

if the question says 40 times negative 20x equals 20 the answer is [tex]x=-\frac{1}{40}[/tex]

if the question is 40x minus 20x equals 20 then the answer is x=1

Check the picture below.

[tex]\stackrel{\textit{area of all 6 faces}}{6(9.9\cdot 9.9)\implies 6(98.01)}\implies 588.06~~ \approx ~~600~in^2[/tex]

Answer:

The rule is y = x - 9

n = 11

Step-by-step explanation:

To find patterns, we just have to look at the table and see if there are any repeating rules.

Well, the y values go from 1 to 3 to 6

3 - 1 = 2

6 - 3 = 3

Nothing similar there.

But, we can see that 10 - 1 = 9

12 - 3 = 9

When you subtract 9 from each x value, you get the y value

So, y = x - 9

n = 20 - 9

20 - 9 = 11

Ratio remains same

[tex]\\ \rm\rightarrowtail \dfrac{12}{3}=\dfrac{20}{n}[/tex]

[tex]\\ \rm\rightarrowtail 4=20/n[/tex]

[tex]\\ \rm\rightarrowtail n=20/4[/tex]

[tex]\\ \rm\rightarrowtail n=5[/tex]

Answer:

D: A bond between two atoms

Step-by-step explanation:

Explanation:

Consider the point (1,2). If we apply the rule [tex](x,y) \to (-x,y)[/tex], then it would move to (-1,2).

The x coordinate flipped in sign from positive to negative. The y coordinate stays the same.

Another example is (-3,7) reflecting to (3,7).

Answer:

n=25

Step-by-step explanation:

Using the relation that describes the measure of the angle formed by two secants being equal to half of the difference of the 2 arcs (large arc-small arc) we can establish the relation;

[tex]10 = \frac{45 - n}{2} [/tex]

[tex]20 = 45 - n[/tex]

[tex] - 45 + 20 = - n[/tex]

[tex] - 25 = - n[/tex]

[tex]n = 25[/tex]

Answer:

  3/10 lb

Step-by-step explanation:

The amount needed for a fraction of a pie is that fraction times the amount needed for the whole pie:

  (4/5) × (3/8 lb) = (4·3)/(5·8) lb = (3/5)(4/8) lb = 3/(5·2) lb

  = 3/10 lb

Mr. Anderson would need 3/10 pounds of apples for 4/5 of an apple pie.

Answer:

10

Step-by-step explanation:

The absolute value function always gives a positive value, that is

| - a | = | a | = a

Given

| 3f - 2g |  + 2 ← substitute f = - 2 and g = 1

= | 3(- 2) - 2(1) | + 2

= | - 6 - 2 | + 2

= | - 8 | + 2

= 8 + 2

= 10

Answer:

1)The dependent is the number of cars produced. The independent is the amount of time

2)I know that the number of cars produced is the dependent because it will change whenever the amount of time changes

3)This relationship is linear because as you get more time, you will get more cars

4)I could create a graph because I could plot down these points and find the slope

5) I would need a couple more points to plot

angle sum of triangle

180-112-48

There are two ways , so the first part reference to method 1 and and second part reference to method 2.

[tex] \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \tt In~\triangle ABC: [/tex]

[tex] \\ [/tex]

[tex] \tt \angle A + \angle B + \angle C = 180 {}^{ \circ} [/tex]

{sum of triangle}

[tex] \\ \\ [/tex]

here we can find value of angle C.

[tex] \\ [/tex]

[tex] \dashrightarrow \sf\angle A + \angle B + \angle C = 180 {}^{ \circ} \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow \sf112 + 48 + \angle C = 180 {}^{ \circ} \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow \sf160 + \angle C = 180 {}^{ \circ} \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow \sf\angle C = 180 {}^{ \circ} - 160 {}^{ \circ} \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow \sf\angle C =20^{ \circ} \\ [/tex]

[tex] \\ \\ [/tex]

angle c is congruent to angle f

.°. y = 20°

[tex] \\ \\ [/tex]

[tex] \\ \\ [/tex]

angle a = angle d

.°. value of x = 112°

[tex] \\ \\ [/tex]

[tex] \tt \angle E + \angle D + \angle F = 180 {}^{ \circ} [/tex]

[tex] \\ \\ [/tex]

ve can find value of y :-

Answer:

[tex]\% = 53.8 \%[/tex]

Step-by-step explanation:

Given

[tex]Yes = 483[/tex]

[tex]No = 807[/tex]

[tex]Maybe = 210[/tex]

Required

Determine percentage of "No"

First, we need to determine the total population

[tex]Total= 483 + 807 + 210[/tex]

[tex]Total= 1500[/tex]

Percentage of No is then calculated as follows:

[tex]\% = \frac{No}{Total} * 100\%[/tex]

[tex]\% = \frac{807}{1500} * 100\%[/tex]

[tex]\% = \frac{80700}{1500} \%[/tex]

[tex]\% = 53.8 \%[/tex]
