Answer:
step below and graph
Step-by-step explanation:
y intercept: x=0 y = (-1/18) * 3 * (-3) * (-4) = - 2
y = -1/18 * (x³ - 4x² - 9x +36) ... leading coefficient: (-1/18 x³) -1/18
highest degree:( x³) 3
Answer:
2 y x
Step-by-step explanation:
Answer: Company A would be a better deal for number of minutes over 200
Step-by-step explanation:
Let x represent the number of minutes that you would use with either company A or company B.
Company A has a monthly charge of $10 plus 5¢ a minute for each minute of long distance calls. It means that the cost of x minutes of long distance call is
10 + 0.05x
Company B has a monthly charge of $8 plus 6¢ a minute for long distance calls. It means that the cost of x minutes of long distance call is 10 + 0.05x
8 + 0.06x
For Company A to be a better deal, it means that
10 + 0.05x < 8 + 0.06x
10 - 8 < 0.06x - 0.05x
2 < 0.01x
0.01x > 2
x > 2/0.01
x > 200
