Combine like terms so add 4b and 15b together and add 7 and 3 together and then the answer would be 19b-10
The answer would be 3z(5x + 7y)
Answer:
Function 1 written in vertex form is f(x) = -x^2 + 8x - 15 = -(x^2 - 8x + 15) = -(x^2 - 8x + 16 + 15 - 16) = -(x - 4)^2 - (-1) = -(x - 4)^2 + 1
Therefore, vertex = (4, 1)
Function 2 written in vertex form is f(x) = -x^2 + 4x + 1 = -(x^2 - 4x - 1) = -(x^2 - 4x + 4 - 1 - 4) = -(x - 2)^2 - (-5) = -(x - 2)^2 + 5
Therefore vertex = (2, 5)
Function 1 has a maximum at y = 1 and function 2 has a maximum at y = 5. Therefore, function 2 has a larger maximum.
Step-by-step explanation:
The answer would be (4,3)
If a polynomial has real coefients, if a+bi is a root, then a-bi is also a root
so
8 and i and 6i
since i and 6i is zeores then -i and -6i are also zeroes
remaining zeroes are -i and -6i
