Answer: 2
Reason:
2x^3 - 11x^2 + 12x + 9
= 2x^2(x-3) - 5x(x-3) -3(x-3)
= (x-3)(2x^2 - 5x - 3)
= (x-3)^2 (2x + 1)
The function is a parabola which opens downwards.
-x^2 - 2x + 15
-(x^2 + 2x) + 15
= -[(x + 1)^2 - 1 ]+ 15
= -(x + 1)^2 + 16
The domain is all real numbers and the range is {y|y <= 16}
Its the second choice.
Answer:
See below and attached
Step-by-step explanation:
Let the number of paintings is x and the number of mugs is y.
<u>We have following inequalities:</u>
- x + y ≤ 350
- 20x + 15y > 4500
The graphical solution is attached.
<u>The solution is:</u>
- 225 < x ≤ 350
- 300 < y ≤ 350
152 inches cubes because when I done this in my class he gave us the answer
12 1/10
A quick way to get this one is to recognize that .1 is a decimal in the tenth place. Because of this, we know to put it over 10. Because 1/10 cannot be simplified, it is in simplest form. Now, simply return the whole number to the fraction.
