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.

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]

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.

Gracie’s bill at a restaurant is $15. Sales tax is 6% and she plans to leave a 20% tip (on the total after tax is added). What is the total amount of money she’ll pay, including tax and tip?

Answers

sales tax would be 0.90 then add the 20% would be 3.00 so 15 + 0.90 + 3 = ur answer

Answer:

She will pay $19.08

Step-by-step explanation:

6/100=0.06

15(0.06)=0.90

15.00+0.90=15.90

20/100=0.2

(15.90)(0.2)=3.18

15.90+3.18=$19.08
