Answer:

Hi there!

The answers are -9 and 5.

Step-by-step explanation:

On a number line you can either go left (towards the negative side) or right (towards the positive side) since it is asking what numbers are a distance of 7 units from -2, there are two methods you must use;

-2 + 7 means you are moving 7 units to the right and you get 5

-2 -7 means you are moving 7 units to the left and you get -9

Answer: 9 and -9

Step-by-step explanation: First, identify the problem. Then, subtract it in both ways. -2 minus 7 and 7 minus -2. Simple. You should be able to acquire your answers quite easily if you subtract properly. After all that, you should end up with 9 and -9. If you did not, however, you subtracted wrong. Thank you for reading!

5. Find the slope that intersects the x-axis at (1,3) and the y-axis at (4,7).

kotykmax [81]

For this case we have that by definition, the slope of a line is given by:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}$

Where:

$(x_ {1}, y_ {1})\\(x_ {2}, y_ {2})$

They are two points through which the line passes.

According to the statement we have two points:

$(x_ {1}, y_ {1}) :( 1,3)\\(x_ {2}, y_ {2}) :( 4,7)$

Substituting we have:

$m = \frac {7-3} {4-1} = \frac {4} {3}$

Thus, the slope of the line is:

$\frac {4} {3}$

Answer:

$\frac {4} {3}$

The table represents an exponential function.

3/4

The easiest way to solve this is to test the numbers one by one. 2/3 is not the answer because 2/3 times 3/2 is 1, not 9/8. It is 3/4 because 3/2 times 3/4 is 9/8, 9/8 times 3/4 is 27/32, and so forth.

Help me i can’t do this

DerKrebs [107]

Answer:

$\huge\boxed{\sf Star = 14}$

Step-by-step explanation:

Let snowman be x , star be y and shopping bag be z.

<u>So, the given equations are:</u>

1) x + y = 20 (Eq. 1)

2) z = x + x

z = 2x (Eq. 2)

3) z + x = 18 (Eq. 3)

Put Eq. (2) in Eq. (3)

2x + x = 18

3x = 18

Divide both sides by 3

x = 18 / 3

x = snowman = 6

Now, Put x in (Eq. 1)

6 + y = 20

Subtract 6 to both sides

y = 20 - 6

y = 14

So,

Star = 14

$\rule[225]{225}{2}$

Hope this helped!
