Answer:
Direct Variation Use y=kx. Means “y varies directly with x.” k is called the constant of variation. “y varies inversely with x.” k is the constant of variation.
Step-by-step explanation:
Answer:
63
Step-by-step explanation:
F(x) = x² + 5x
F(5) = (5)² + 5(5) = 25 + 25 = 50
G(x) = 2x + 1
G(6) = 2(6) + 1 = 12 + 1 = 13
F(5) + G(6) = 50 + 13 = 63
Answer:
-31.9%
Step-by-step explanation:
In this problem, the initial price of the ticket for the movie Black Panther is

Later, the price of the ticket is decreased to

The percent change can be written as

Which is the ratio between the difference in price and the original price, multiplied by 100.
By substituting the values inside the formula, we find:

Where the negative sign indicates a decrease.
Y = -1.4
The simplest way to find the answer is to cancel out the x - values. Set both equations equal to zero.
10x + 8y + 24 = 0
5x - 6y - 2 = 0
Multiple the second equation by -2 so the x terms cancel out when you add them together.
10x + 8y + 24 = 0
-10x + 12y + 4 = 0
20y + 28 = 0
20y = -28
Y = -1.4
