The answer I think is this
fx=x^2-3
Answer:
27 and 23
Step-by-step explanation:
x + y = 50
x - y = 4
2x = 54
x = 27
y = 23
f(x) = x³ - 2x² - 24x
x³ - 2x² - 24x = 0
x(x² - 2x - 24) = 0
x = 0
x² - 2x - 24 = 0
a = 1, b = -2, c = -24
Delta = (-2)² - 4 * 1 * (-24) = 4 + 96 = 100
x = (-(-2) - 10)/(2 * 1) = -8/2 = -4
x = (-(-2) + 10)/(2 * 1) = 12/2 = 6
Answer: 2)
Answer:
(5,4) & (8,-10)
Step-by-step explanation:
First step:
You can use any number you want for b (I used 4)
Make x=0
Make y=0
Subtract 4 from both sides
Divide both sides by 
Second step:
In order to make a line perpendicular to another the slope of the second line will be the negative inverse of the first line. So 
will be 
for the second line.
Then you just need to repeat the process in first step to get the intercepts. (Again I used a random number like -10 for b)
Answer:
Each page of the album contains 8 cards.
Step-by-step explanation:
Let us assume that each page of the album contains x number of cards.
Now, Mr. Harrid gave each of his two children an equal number of his baseball card collection.
He gave Tony an album with cards on 15 pages and a stack of 25 cards that still need to be put in the album and he gave his daughter Paula an album that has 10 cards and a stack of 65 cards to put in her album.
Therefore, Tony has (15x + 25) cards and Paula has (10x + 65) cards.
Hence, (15x + 25) = (10x + 65)
⇒ 5x = 40
⇒ x = 8
Therefore, each page of the album contains 8 cards. (Answer)
