Answer:
21 years
Step-by-step explanation:
Lawrence did research on many different swimmers. He graphed each swimmer with a tick on the graph. The more ticks, the higher amount of people. <em>Because most of the ticks are on 21, If I did this right, It should be 21.</em>
Answer:
-12x + 4
Step-by-step explanation:
(6x - 8 - 2x) - (12x - 7) - (4x - 5)
The subtraction sign before the parenthesis is basically multiplying by -1, so the subtraction signs in the parenthesis have to change to addition. After that, you can remove the parenthesis.
6x - 8 - 2x - 12x + 7 - 4x + 5
Simplified = -12x + 4
Answer:
-1.
Step-by-step explanation:
First find the derivative of f(x):
f'(x) = -3x^2 + 12x - 9 = 0 for a maximum or minimum.
-3(x^2 - 4x + 3) = 0
(x - 1)(x - 3) = 0
x = 1, 3.
To find which gives a relative maximum we find the second derivative:
f"(x) = -6x + 12
When x = 1 f"(x) = 6, positive.
when x = 3, f"(x) = -6, negative.
So x = 3 gives a maximum value of f(x).
f(3) = -(3)^3 + 6*(3)^2 - 9(3) - 1 = -1 (answer).
Answer:
So first you would add the to numbers 56+84 to get 140. then you would put it in fraction form of males to total people (56/140). Then by simplifying you would get the answer of 2/5!
Step-by-step explanation:
Sammy was selling tickets for the football game. He sold five more adult tickets (AT) than senior tickets (ST) and twice as many children's tickets (CT) than senior tickets. Let s represent the number of senior tickets sold
ST = AT - 5
CT = 2ST = 2(AT - 5)
