Answer:
(- 5, 0) and (3, 0)
Step-by-step explanation:
Given
f(x) = x² + 2x - 15
To find the x- intercepts let f(x) = 0, that is
x² + 2x - 15 = 0 ← in standard form
(x + 5)(x - 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5 ← left x- intercept
x - 3 = 0 ⇒ x = 3 ← right x- intercept
Answer:
it should be A if not im sorry
Step-by-step explanation:
2/8 or 1/4. 1/4 is just simplified. I hope it helps!
Approximately 14%
14-12=2
2/14=1/7
1/7*100=14.29
14.29%

Step-by-step explanation:
Total number of days
The number of days she bought a banana or orange
The probability of buying a banana or an orange is
- P(b or o) = 21/30 = 0.7 = 70%
