X^3 - 21x = -20
add 20 to both sides
x^3 - 21 x + 20 = 0
Rational Root Theorem:
Factors of P (constant) 20 = 1, 2, 4, 5, 10, 20
-------------------------------
Factors of Q (leading Coefficient) = 1
Possible zeros (all + -) 1/1, 2/1, 4/1, 5/1, 10/1, 20/1
Of the choices given only the number 1 is a possible root.
Answer:
Anton played a total of 39 games.
Step-by-step explanation:
If you want to calculate the amount of games played, you must first subtract the membership fee of 895 to get 1170. As you are charged $30 for each game, you must divide by thirty.
If you are fond of graphing, know this equation can also be expressed in slope-intercept form (y = mx + b) as y = 30x + 895, with x being the number of games played and the y-intercept (895) being your initial cost.
This is a right triangle (you can confirm by using Pythagorean Theorem: 15² + 36² = 39²)
A = ![\frac{1}{2} b * h](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20b%20%2A%20h)
A = ![\frac{1}{2} 15 * 36](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%2015%20%2A%2036)
= 15 * 18
= 270
