If F(x) = x² + 5x and G(x) = 2x + 1, find F(5) + G(6). 48 63 107
Sergio [31]

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

Fatim is hosting a viewing party for the new movie black Panther. Fatim decided to change ticket prices from $17.99 to $12.25 a
Elden [556K]

Answer:

-31.9%

Step-by-step explanation:

In this problem, the initial price of the ticket for the movie Black Panther is

p_i = \$17.99

Later, the price of the ticket is decreased to

p_f = \$12.25

The percent change can be written as

c=\frac{p_f-p_i}{p_i}\cdot 100

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:

c=\frac{12.25-17.99}{17.99}\cdot 100=-31.9\%

Where the negative sign indicates a decrease.

What is the y-value for the solution to the system of equations below? 10x + 8y = -24 5x+6y = 2​
Sergeeva-Olga [200]
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
