Answer:
y = -5/12
Step-by-step explanation:
−3(y+3)=2y+3 (multiply -3 with inside the parenthesis)
➡
-3y -9 = 2y +3
➡
-3y -2y = 3+9 add like terms
➡
-5y = 12
➡
y = -5/12
Answer:
Step-by-step explanation:
We know that sin²Ф+cos²Ф=1
when you divide both sides by cos²Ф you get
sin²Ф/cos²Ф+cos²Ф/cos²Ф=1/cos²²Ф
sin²Ф/cos²Ф=tan²Ф
cos²Ф/cos²Ф=1
1/cos²Ф=sec²Ф
tan²Ф+1=sec²Ф
subtract tan²Ф on both sides
1=sec²Ф-tan²Ф
therefore sec²Ф-tan²Ф=1
Answer:
A. One solution
Step-by-step explanation:
To find out, we solve the equation.
6 - 3x = 12 - 6x
Add 6x to both sides. Subtract 6 from both sides.
3x = 6
Divide both sides by 3.
x = 2
Answer: A. One solution
