Sin x = cos (90-x)
90-x = 19
x = 71
The answer is 71 degrees.
It must be ≤ instead of ≥.
y ≤ - 3·x + 4
Answer:
Divide by 3 on both sides.
Step-by-step explanation:
Original Expression: 3(x+2) = 12
Divide by 3 on both sides: x+2 = 4
Subtract 2 from both sides: x=2
Let me know if this helps!
Y=x^2-5, solve for x
y+5=x^2
x=√(y+5) so
f^-1(x)=√(y+5)
