Answer:
Lower
Step-by-step explanation:
Use the number 100 to see how the value changes:
First, calculate the 60% drop:
100(0.4)
= 40
Then, calculate the 75% increase:
40(1.75)
= 70
So, since 70 is smaller than 100, the value is lower than where it started.

Answer:
part a - 122.39
part b - 91.79
Step-by-step explanation:
Consider this option:
1. rule: the equation will be the same if the both its parts are multiplied by one number ('0' is not included!).
2. using the rule, described upon:
-3x-2y=-7 (*(-1));
6x+4y=14 (*2);
-6x-4y=-14 (*(-2)).
Note, that not all the ways are described.
Answer:
B
Step-by-step explanation:
using the cofunction identity
• sin (90 - x) = cosx / cos(90 - x) = sinx, hence
cos 19° = sin(90 - 19)° = sin 71°
