I could be wrong but .165% would be my guess it it’s not 165% or 1650%
Y=(1)/(3)x-9 that’s the answer
x>7
Step-by-step explanation:
when dividing by a (-)
the inequality sign changes
The temperature decreased by 5 degrees per hour, as -25 / 5 is -5.
With some simplification,
cos⁻¹(x) - 5 cos⁻¹(x) - π/3 = 2π/3
becomes
-4 cos⁻¹(x) = π
or
cos⁻¹(x) = -π/4
However, the inverse cosine function has a range of 0 ≤ cos⁻¹(x) ≤ π, so there are no solutions to this equation.
