Answer:
2x (2x^2 +x +1)
Step-by-step explanation:
f(x)-g(x)
9x^3 + 2x^2 -5x + 4 - (5x^3 -7x +4)
9x^3 + 2x^2 -5x + 4 - 5x^3 +7x -4
4x^3 +2x^2 +2x
2x (2x^2 +x +1)
Answer:
C. Table B, Graph B.
Step-by-step explanation:
The volume of a cone with diameter d (and hence radius d/2) and height h is
so each scoop holds
of coffee.
The volume of a cylinder with base diameter d and height h is
so the coffee can contains
of coffee.
One full scoop then uses up of the total amount of coffee in the can, so you can make 12,150 cups of coffee.
D. 40 percent
Adding everything up that he spent money on, we get $744 dollars. That's out of a total of his $1240 dollars.
So we can find out how much money he has left by subtracting the total from the amount he spent.
1240 - 744 = 496
$496 dollars is the amount of money he has left. To find out the percentage he has left, put the remaining amount over the total times 100.
So, 496/1240 = .4
.4 × 100 = 40 percent. Hope that helps!
Answer:
x = 3
y = 4
hey, I am not 100% sure of the certainty of my answers, I am using what I remember about that topic but I do not know if it is right or wrong, I hope I have helped you, I did what I could.
Step-by-step explanation:
-3x + 2y = 23
5x + 2y = -17
X solution:
(you cancel the y)
-3x = 23
5x = -17
(you combine all the values above with those below)
2x = 6
(solve the ecuation normaly)
x = 6/2 = 3
Y solution:
(you replace the x)
-3(3) + 2y = 23
5(3) + 2y = -17
-9 + 2y = 23
15 + 2y = -17
(you combine all the values above with those below)
6 + 4y = 6
(solve the ecuation normaly)
4y = 0
y = 4
(I do not really know if the answer here is 0 or 4 since when passing the 4 to divide it would be 0/4 and I do not understand very well how that is solved)
