Answer:
y = -75
Step-by-step explanation:
Simplify both sides of equation
1/5y = -15
multiply both side by 5
1/5y * 5 = -15 * 5
y = -75
Answer:
x = 3
Step-by-step explanation:
3x + 3 = 6 + 6
3x + 3 = 12
3x = 12 - 3
3x = 9
x = 3
3 (3) + 3 = 6 + 6
9 + 3 = 12
12 = 12
Answer:
Step-by-step explanation:
This question is asking us to find where sin(2x + 30) has a sin of 1. If you look at the unit circle, 90 degrees has a sin of 1. Mathematically, it will be solved like this (begin by taking the inverse sin of both sides):
![sin^{-1}[sin(2x+30)]=sin^{-1}(1)](https://tex.z-dn.net/?f=sin%5E%7B-1%7D%5Bsin%282x%2B30%29%5D%3Dsin%5E%7B-1%7D%281%29)
On the left, the inverse sin "undoes" or cancels the sin, leaving us with
2x + 30 = sin⁻¹(1)
The right side is asking us what angle has a sin of 1, which is 90. Sub that into the right side:
2x + 30 = 90 and
2x = 60 so
x = 30
