12. You divide 30 by 5 to get 4. Then multiply 4 by 3 to get 12. You need 12 oz of red. Hope this helps!
Answer: x= 12/5
Step-by-step explanation:
Cos(t/2) I got .45 is that what you were looking for or do I need to plug it into the equation up top? can you give me notes of something? cos( -9/11/2) = .45

Step-by-step explanation:</h2>
From the given graph, we can know two points:
![P_{1}(x_{1},y_{1})=(2,0) \ and \ P_{2}(x_{2},y_{2})=(1,3)](https://tex.z-dn.net/?f=P_%7B1%7D%28x_%7B1%7D%2Cy_%7B1%7D%29%3D%282%2C0%29%20%5C%20and%20%5C%20P_%7B2%7D%28x_%7B2%7D%2Cy_%7B2%7D%29%3D%281%2C3%29)
Using the slope intercept form of the equation of a line, we get:
![y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x_{1}) \\ \\ y-0=\frac{3-0}{1-2}(x-2) \\ \\ y=-3(x-2) \\ \\ y=-3x+6](https://tex.z-dn.net/?f=y-y_%7B1%7D%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%28x-x_%7B1%7D%29%20%5C%5C%20%5C%5C%20y-0%3D%5Cfrac%7B3-0%7D%7B1-2%7D%28x-2%29%20%5C%5C%20%5C%5C%20y%3D-3%28x-2%29%20%5C%5C%20%5C%5C%20y%3D-3x%2B6)
Where the slope is
and the y-intercept is ![b=6](https://tex.z-dn.net/?f=b%3D6)
From mathematics, we know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept. So, from the options, the second equation is:
![y=-3(x+6)](https://tex.z-dn.net/?f=y%3D-3%28x%2B6%29)
And the slope intercept form of this equation is:
![y=-3x-18](https://tex.z-dn.net/?f=y%3D-3x-18)
So the slope is
and the y-intercept is
, the systems formed by these two equations has no solution.
