Answer:
Bailey played longer.
Step-by-step explanation:
1/3 of an hour would be 20 minutes. 1/6 of an hour is 10 minutes.
Answer:
y = 1/3x - 4
Step-by-step explanation:
Lol lemme just write out the steps and if you're confused just comment and i'll get back to u.
x - 3y = 12
<u>-x.........-x</u>
-3y = -x + 12
<u>*-1...........*-1</u>
3y = x - 12
<u>/3........../3</u>
y = 1/3x - 4

And that is the equation in fully simplified slope/intercept form. I hope this helps!
The solution to the system of equation is (1, 4).
In order to find this, we can first just see where the graphs intersect each other. This will give us the solution set.
As for what it represents, the x value in the increase in temperature and the y value is the increase in customers.
Therefore, we know that we want the temperature to go up by 1 (although we don't know the units) and that would result in the amount of people coming, and staying longer by 4 (again, we don't know the units of measure).
Our matrix C is the encoder. Let X be our secret message and let B be our encoded message. Therefore the relationship between the 3 can be represented as:
CX = B
So we want to solve for X (our secret message). So using matrix algebra:
X = C^-1*B
where C^-1 is the inverse of C.
C^-1 = | 3 -2 |
|4 -3 |
So we take C^-1 and multiply it by matrix B to get X. Matrix B is already given to us. So just multiply those two. I used a calculator to get:
X = | 20 8 5 3 15 12 15 |
| 18 9 19 2 12 21 5 |
And since A = 1, B = 2, C = 3, etc....
We decode our message and it says:
X = | T H E C O L O |
| R I S B L U E |
So the answer is: The color is blue (D)
