Answer:
Algebra 1 Answer Key with notes.pdf go on that and there are the anwers and the answer key :)
Step-by-step explanation:
It is an easier and faster way to write an equation for the slope of a line if you already have its points and slope.
We must graph y=x^3-9x^2+11x+21. Please, see the attached file.
Then we see were the graph cuts the x-axis, and these values of x are the real solutions of the given equation:
The real solutions of the given equation are:x = -1, 3, and 7
Answer:
Absolute minimum = 1.414
Absolute maximum = 2.828
Step-by-step explanation:

For absolute minimum we take the minimum values of
and
.

Plugging in the minimum values in the function.

Absolute minimum value will be always positive.
∴ Absolute minimum = 1.414
For absolute maximum we take the maximum values of
and
.

Plugging in the maximum values in the function.

Absolute maximum value will be always positive.
∴ Absolute maximum = 2.828
Answer:
x = 16
Step-by-step explanation:
x
-- = 9-1 ...... first shift 1 and it will be -1
2
x = 8 ....... secondly 9-1 =8
--
2
x = 16 ..... criss cross and 2×8 = 16
there fore the value of x is equals to 16.
you can check it!
