I believe it should be A.
Answer:
b) -10
Step-by-step explanation:
x^2 + 3x + k = (x - 2)(x - a)
(x - 2)(x - a) = x^2 - 2x - ax + 2a = x^2 + [-2 - a)x] + 2a
-2 - a = 3
2a = k
a = -5
k = 2(-5) = -10
Answer: b) -10
i answer the questions that relate to the lessons i've learned
Answer:
squid, crab, tuna, eel
Step-by-step explanation:
Just make each sushi piece into an equation, then solve it.
For example, for the squid: (s stands for squid)
Divide both sides by 2 to get "s" by itself
Eel: (e stands for eel)
e = 3.25
Tuna: (t stands for tuna)
Divide both sides by 3 to get "t" by itself
Crab: (c stands for crab)
Divide both sides by 4 to get "c" by itself
**Then order from least to greatest**
Given:
2009 : 3,500 population
decrease of 2.2% per year.
100% - 2.2% = 97.8%
2014 - 2009 = 5 years
3,500 * (0.978)^5 = 3,500 * 0.89473 = 3131.57
The bird population in 2014 will be 3,131.57 or 3,132.
