Answer:
x^3 + x^2 + 4x - 20.
Step-by-step explanation:
I have assumed there is a + between the 3x and the 10.
f(x) * g(x)
= (x^2 + 3x + 10)(x - 2)
= x^3 + 3x^2 + 10x - 2x^2 - 6x - 20
= x^3 + x^2 + 4x - 20.
X=7
But to show your work you would put
-1x=7
Then divide -1x by -1 and 7 by -1 to cancel it out, and you get x=8
Answer:
Option B is correct
Step-by-step explanation:
Given data
We are given the expression
-4x + 2y > 12
We want to substitute y=4 into the expression
-4x + 2(4) > 12
-4x + 8 > 12
-4x> 12-8
-4x> 4
divide both sides by -4
x> 4/-4
x>-1
Hence option B is correct
Answer:
The answer you have selected should be correct.
Answer:
The function is decreasing in the following intervals
A. (0, 1)
C. (2, pi)
Step-by-step explanation:
To answer this question, imagine that you draw lines of slope m parallel to the function shown at each point.
-If the slope of this line parallel to the function is negative for those points then the function is decreasing.
-If the slope of this line parallel to the function is positive for those points then the function is increasing.
Observe in the lines drawn in the attached image. You can see that they have slope less than zero in the following interval:
(0, 1) U (2, pi)
Therefore the correct option is:
A. (0, 1)
C. (2, pi)
