Answer:
x-intercepts: (2, 0) and (−5, 0)
y-intercept: (0, −10)
Step-by-step explanation:
y = x^2 + 3x − 10
y-intercept when x = 0 so y = -10, so y-intercept : (0, -10))
x-intercept when y = 0 so
x^2 + 3x − 10 = 0
(x +5)(x - 2) = 0
x + 5 = 0; x = -5
x - 2 = 0; x = 2
So x-intercepts: (-5, 0) and (2,0)
Answer:
75%
Step-by-step explanation:
To find how much percent of the team won, you have the event over the sample space.
So n(E)/n(S) = 63/84 = 3/4 = 0.75 = 75%

Answer: $650
Step-by-step explanation:
If he sold the bike 10% less than the original amount which means he sold it as a 10% discount so the person has to pay 90% of the price. And 90% of the price has to equal $585 so we could set up an equation and solve for the price.
90% * x = 585
0.9 * x = 585
0.9x = 585
x = 650
Which means he paid $650 for the bike.
