Answer:
b. a = negative 1, b = 5, c = 0
Step-by-step explanation:
y = negative x squared + 5 x
y = -x² + 5x
a = -1
b = 5
c = 0
11m-6m = 22+8
5m = 30
m = 6
Hope I helped :)
For this case we must simplify the following expression:
![\frac {1} {2} -3 (\frac {1} {2} +1) ^ 2](https://tex.z-dn.net/?f=%5Cfrac%20%7B1%7D%20%7B2%7D%20-3%20%28%5Cfrac%20%7B1%7D%20%7B2%7D%20%2B1%29%20%5E%202)
Then we have to start by solving the operation within the parenthesis:
![\frac {1} {2} -3 (\frac {1 + 2 * 1} {2}) ^ 2 =\\\frac {1} {2} -3 (\frac {3} {2}) ^ 2 =\\\frac {1} {2} -3 (\frac {3} {2} * \frac {3} {2}) =\\\frac {1} {2} -3 (\frac {9} {4}) =\\\frac {1} {2} - \frac {27} {4} =\\\frac {4 * 1-2 * 27} {4 * 2} =\\\frac {4-54} {8} =\\\frac {-50} {8} =\\- \frac {25} {4}](https://tex.z-dn.net/?f=%5Cfrac%20%7B1%7D%20%7B2%7D%20-3%20%28%5Cfrac%20%7B1%20%2B%202%20%2A%201%7D%20%7B2%7D%29%20%5E%202%20%3D%5C%5C%5Cfrac%20%7B1%7D%20%7B2%7D%20-3%20%28%5Cfrac%20%7B3%7D%20%7B2%7D%29%20%5E%202%20%3D%5C%5C%5Cfrac%20%7B1%7D%20%7B2%7D%20-3%20%28%5Cfrac%20%7B3%7D%20%7B2%7D%20%2A%20%5Cfrac%20%7B3%7D%20%7B2%7D%29%20%3D%5C%5C%5Cfrac%20%7B1%7D%20%7B2%7D%20-3%20%28%5Cfrac%20%7B9%7D%20%7B4%7D%29%20%3D%5C%5C%5Cfrac%20%7B1%7D%20%7B2%7D%20-%20%5Cfrac%20%7B27%7D%20%7B4%7D%20%3D%5C%5C%5Cfrac%20%7B4%20%2A%201-2%20%2A%2027%7D%20%7B4%20%2A%202%7D%20%3D%5C%5C%5Cfrac%20%7B4-54%7D%20%7B8%7D%20%3D%5C%5C%5Cfrac%20%7B-50%7D%20%7B8%7D%20%3D%5C%5C-%20%5Cfrac%20%7B25%7D%20%7B4%7D)
ANsweer:
