Answer is the second one!
Answer:
Step-by-step explanation:
I don't really know what your question is asking for but I can tell you there's a quadratic formula that solves for x-ints. There's a quadratic equation which is Ax + bx + c = 0.
Since she makes $13 per hour, she would have to work 5 hours to make $65.
Answer:
The lines DE and BC have the same slope, therefore the two lines, DE and BC, are parallel
Step-by-step explanation:
To prove that DE is parallel to BC, we have;
The slope, m of the lines DE and BC are found from the following equation;
![Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=Slope%2C%20%5C%2C%20m%20%3D%5Cdfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
Where;
(x₁, y₁) and (x₂, y₂) = (b, c) and (a + b + c) for DE, we have;
![Slope, \, m =\dfrac{c - c}{a + b-b} = 0](https://tex.z-dn.net/?f=Slope%2C%20%5C%2C%20m%20%3D%5Cdfrac%7Bc%20-%20c%7D%7Ba%20%2B%20b-b%7D%20%3D%200)
Where we have (x₁, y₁) and (x₂, y₂) = (0, 0) and (2a, 0) for BC, we have;
![Slope, \, m =\dfrac{0 - 0}{2a-0} = 0](https://tex.z-dn.net/?f=Slope%2C%20%5C%2C%20m%20%3D%5Cdfrac%7B0%20-%200%7D%7B2a-0%7D%20%3D%200)
Therefore, because the lines DE and BC have the same slope, the two lines DE and BC are parallel.
The answer is c!!!!!!!!!!!!!!!!!!!!!!!!
