Step-by-step explanation:
To find out how much Billy will pay, just multiply 12 and 2.50
12 x 2.50 = $30
Answer:
7. x = 4
8. x = 10
Step-by-step explanation:
7. The angles are equal to each other so you can do
40 = 12x - 8
48 = 12x
4 = x
8. The angles add up to be 180 degrees so you can combine them and set them equal to 180
6x + 12x = 180
18x = 180
x = 10
Answer:Y, R, B, G
Step-by-step explanation:
Order matters since the ball is being replaced each time. This is all the possible combinations to take 2 balls with replacement, so you can look at the list and see that RR, RB, and RG are listed. The only other combination when choosing a red first would be to pick a yellow, so RY. This is the same pattern for the others also. Look at the list and see what combinations are already listed.
Answer:
<em>The value of y when x has a value of 9 is 18</em>
Step-by-step explanation:
<u>Functions</u>
The variables x and y are said to have a quadratic relationship. That information is not enough to set up a general equation for both variables.
Furthermore, we know that tripling the value of x causes the value of y to be multiplied by 9. That leads us to establish a proportional equation between them, as follows:
Where k is an unknown constant.
Let's use the given point (3,2) to find the value of k:
Solving for k:
The equation is now:
Now find y when x=9:
The value of y when x has a value of 9 is 18
