Step-by-step explanation:
a
Answer:
3 3/7
Step-by-step explanation:
7x+2v=48
2v. -2
-------
46
7x+46=48
-46. -46
---------------------
7x=2/7. x=2/7=1/7
x=1/7
The function has a maximum at (1, 3).
_____
You know it is not a minimum because the coefficient of the squared term is negative.
You know the vertex is (1, 3) because you match the pattern to
.. y = a(x -h)^2 +k
which has its vertex at (h, k).
c. (x + 5)(x - 7) use the FOIL method.
x² + 5x - 7x - 35
x² + (5x - 7x) - 35 collect like terms.
x² - 2x - 35
hope that helps, God bless!
