Answer:
x=1
Step-by-step explanation:
Answer:
The roots are -2 and -3
Step-by-step explanation:
In the function x² + bx + c, <em>a</em> is equal to 1, then the factored form of this function is: (x - x1)*(x - x2) where x1 and x2 are the roots.
Wilma got the following expression:
(x - 1)*(x - 6) = x² - 6x - x + 6 = x² - 7x + 6, where '+6' is correct but '-7x' is incorrect.
Greg got the following expression:
(x + 1)*(x + 4) = x² + 4x + x + 4 = x² + 5x + 4, where '+5x' is correct but '+4' is incorrect.
Therefore the quadratic equation is: x² + 5x + 6. Its roots are:
Answer:
84*(1/4)^x
Step-by-step explanation:
84 is the constant as it is the starting amount. However each round (x because the amount of rounds is constantly changing) divides the team by 4 or multiplies by 1/4 (Reciprocal).
So, if you wanted to see if the amount of teams after three rounds you would do:
84 * 1/4 * 1/4 * 1/4. However, any number times itself is an exponent, so we would simplify to 84³. But due to the fact we do not know how many rounds we are going to calculate we change the exponent to x.
