Answer:
21.6
Step-by-step explanation:
If x=14.4
And BC= 36
36-14.4= y
21.6= y= DC
Answer:
D = — 4 < x < 0
or
D = R — ( — ∞ , —4] & [0, + ∞)
First 6, then 11, then 13.5, then (honestly I don't know the rest). '__'
Answer:
C and E
Step-by-step explanation:
The variable "y" has to be by itself so here is the breakdown to that:
-3x + 6y + 5 = - 7
6y + 6 = 3x - 7
6y = 3x - 7 - 6
6y = 3x - 12
6y/6 = 3x/6 - 12/6
y = 1/2 x - 2
Then you would graph -2 --> (0, -2) and use 1/2 to navigate upwards to get your answers.
Answer: See below
<u>Step-by-step explanation:</u>
y = a(b)ˣ
- y: final population of zombies
- a: initial population of zombies
- b: rate of decrease
- x: number of hours
Given: a = 500,000 b = 50% (0.5)
y = 500,000(0.5)ˣ
Since we want to know the number assassinated (A), subtract the total from the final population of zombies
A = 500,000 - y
a) Equation: 500,000 - 500,000(0.5)ˣ
b)

(Graph attached)
c) The assassins will earn 100,000 + 2(499,985) = $1,099,970 after 15 hours.
The number of zombies needed to assassinate in order to earn $1,000,000:
100,000 + 2z = 1,000,000
2z = 900,000
z = 450,000
d) How long will it take to eliminate all of the zombies?
The population of zombies is zero when x = 20 hours
How much money did the assassinators earn?
100,000 + 2(500,000) = $1,100,000
