Help with this question

Mathematics
1 answer:
Sholpan [36]3 years ago
4 0

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.

Need asap help ,struggling !
zepelin [54]

Answer:

A.) x = 1000 kilowatt-hours

Step-by-step explanation:

Because Micah was charged 113.94 total for the month, this is the y value. We are trying to find x, how much electricity he used. We would start by making the equation: 113.94 = 0.11x + 3.94

Now, we need to get x alone.

(Subtract 3.94 from both sides) 110 = 0.11x

(Divide by 0.11) x = 1000 kilowatt-hours

Hope this helps!
