Answer:
video game: $29.50
DVD: $10
Step-by-step explanation:
Let d = price of one DVD, and let v = price of 1 video game.
"A bundle of two video games and three DVDS can be purchased for $89.00."
2v + 3d = 89
"A bundle of one video game and two DVDS can be purchased for $49.50."
v + 2d = 49.5
We have two equations in two unknowns, so we can solve them as a system of 2 equations.
2v + 3d = 89
v + 2d = 49.5
Rewrite the first equation.
Multiply both sides of the second equation by -2 and write it below the first equation.
Add the equations.
2v + 3d = 89
(+) -2v - 4d = -99
---------------------------
-d = -10
d = 10
Now we substitute 10 for d in the second original equation and solve for v.
v + 2d = 49.5
v + 2(10) = 49.5
v + 20 = 49.5
v = 29.5
Answer: video game: $29.50; DVD: $10
The initial height of the ball is the y-intercept of the function
The initial height she threw the ball from is 35
<h3>How to determine the initial height</h3>
The function is given as:
Set x = 0.
So, we have:
Evaluate the exponent
Evaluate the products
Evaluate the sum
Hence, the initial height she threw the ball from is 35

13 - 8 = 5
This is a bad question. It should really be asking about the solutions of f(x)=0 (an actual equation) or the <em>zeros </em>of f(x).
The zeros of a function f(x) are the xs where f(x)=0. That means where the curve intersects the x axis. That's (-4,0) and (2,0) on the graph.
Answer: C (-4,0), (2,0)
