Andre is waiting for the schoo! bus. He knows that 2 out of 6 cars in his town are white. He wants to determine the probability that at least two white cars drive by in a row. He uses a number cube as a
simulation. He lets the numbers 1 and 2 represent a white car and lets all other numbers represent a car that is not white. He rolls the number cube 6 times and records the outcomes in the table below.

Jane takes her cat to the veterinarian. The veterinarian charges a $45 initial charge for the visit plus $22.50 per vaccine. Which equation can be used to find y, the total cost of the appointment, if x represents the number of vaccines?

A. y = 45x + 22.5
B. x = 22.5 y + 45
C. y = 22.5(x + 45)
D. y = 22.5x + 45

Answers

The answer is D

Explanation:22.5 is how much each vaccine is and x is how many vaccines while y is the total cost and 45 is a standard fee

Answer:

From 12 o'clock position clockwise:

-12

-1

11

12

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:

5

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

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]

10. The initial value of the graph is referring to the y-intercept. In this case, it would be -5.
