Infinite! You can, for example, add -1 and 1 to the equation and make it equal. In x=5, you can have x=5+1-1. and it'd still be the same. To add on to it, you could do x+1-1=5+1-1, etc..
The fourth option.
The roots of x^3 + 3x^2 - 5x - 15 are - 3, +√5 and -√5.
To find the roots you can factor the polynomial in this way:
x^3 + 3x^2 - 5x - 15 = x^2 (x + 3) - 5(x + 3) = (x +3)(x^2 - 5)
The roots are the values of x that make the function = 0.
Then the roots are
x + 3 = 0 ==> x = 3, and
x^2 - 5 = 0 ==> x = +/- √5.
45 divided by 4.5, or 4 1/2, would be 10
Answer:
500 pts :DDDD
Step-by-step explanation:
1 ) y = mx + b
hmmm 2 is wrong
2) y = -a+bx+c
I'm unsure about 3 also hmm
3) y = a
Hello there!
Answer: 3x^3 + 3x^2 - 3
Hope this helps! :)
