9. The rate of change is 2/1 or just 2.

Step-by-step explanation:

Basically, X goes up by 1 every single time. Meanwhile Y goes up by 2 every time. So you put 2 on top, and 1 on the bottom and solve.

[tex]\frac{2}{1}[/tex] or just 2, after solving and getting rid of the 1

Answer:

9. 2

10. -5

Step-by-step explanation:

9. The rate of change/slope can be determined by using the formula [tex]\frac{y_{2}- y_{1}}{x_{2}- x_{1}}[/tex]

In this problem, we can choose many different points. For the sake of simplicity, let's choose the first and last points. So [tex](x_{1}, y_{1})[/tex] is (0,-5) and [tex](x_{2}, y_{2})[/tex] is (4,3).

Plugging it in, we get: [tex]\frac{3-(-5)}{4-0} = \frac{8}{4} = 2[/tex]

Answer:

From 12 o'clock position clockwise:

-12

-1

Step-by-step explanation:

y = -1 (given).

x + y = 11

Plug in -1 for y in the equation (given):

x + (-1) = 11

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 1 to both sides of the equation:

x - 1 (+1) = 11 (+1)

x = 11 + 1

x = 12

x + y = ?

x = 12

y = -1

Plug in the corresponding numbers to the corresponding variables:

12 + (-1) = 12 - 1 = 11

xy = ?

x = 12

y = -1

Plug in the corresponding numbers to the corresponding variables. Note that when you multiply a negative and a positive number, your answer will be negative:

12 * -1 = -12

Since Y is -1, X is 12 because 12+-1= 11. Oh and 12•-1 is -12.

8. Explain why 30+1 = 6 is the same as 30 -/-/--/-X-X = 0. What is
the value of x in this example?

Answers

Answer:

Step-by-step explanation:

5 because of two ways one you could do 6*what is 30. Or you could do repeated addition 30=5+5+5+5+5+5. But when you do 30=5-5-5-5-5-5. You are doing repeated subtraction which is equivalent to 30-5*6= 0.

Hope this helps more than the link! :)

the answer if 5 because because you can first divide 30 by 6 then get 5, and you can check that answer by subtracting 6 from 30, 5 times -hope this helps
