D
Explanation:
a: a straight line is 180* and angle 2 and 3 does equal and equal line so that one is true.
b: same with answer a, 4 and 2 make a straight line so it would equal 180*
c: 3 and 4 are vertical angles bc they are a pair of opposite angles on intersecting lines.
d: i ruled out the answers, so D has to be the answer

Answer:
13.5 years
Step-by-step explanation:
The multiplier of the population each year is 5% less than 1, so is 0.95. Then the population in t years is multiplied by 0.95^t. We want to find t such that this value is 1/2.
0.50 = 0.95^t
log(0.50) = t·log(0.95)
log(0.50)/log(0.95) = t ≈ 13.5134 ≈ 13.5
The population will decline to half its original value in approximately 13.5 years.
Answer:
The answer is z = 34.
Step-by-step explanation:
1) Simplify 2 + 8 - z to 10 - z.
2) Subtract 10 from both sides.
3) Simplify - 24 - 10 to -34.
4) Multiply both sides by -1.
