Given:
21 country songs
18 alternative songs
16 pop songs
18 rock songs
Find:
Total number of songs on
Deborah’s Mp3 player using addition and multiplication
Solution:
<span>For addition, we just directly
add all the variables:
21 country songs</span> + 18
alternative songs + 16 pop songs + 18 rock songs = 73 total number of songs
For multiplication, we must
take note that there are two 18 songs with different genre so we can solve it
using multiplication like this:
(18 songs (alternative and
rock) * 2) + 21 country songs + 16 pop songs = 73 total number of songs.
<span>Overall, there are 73 number
of songs in Deborah’s MP3 player.</span>
Answer:
<h2>
y = x² - 1</h2>
Step-by-step explanation:
y = -1 for x = 0 {point(0, -1)} means -1 at the end of formula
If we add 1 to y-coordinate of every given point we get the squares of x-coordinate:
(1, 0): 1² - 1 = 0
(2, 3): 2² - 1 = 4 - 1 = 3
(3, 8): 3² - 1 = 9 - 1 = 8
(4, 15): 4² - 1 = 16 - 1 = 15
So for any x:
(x, y) y = x² - 1
