Answer:
B
Step-by-step explanation:
We can see that this equation is in point-slope form, which is given by the formula:
Where m is the slope and (x₁, y₁) is a point.
We have the equation:
So, we can see that our (x₁, y₁) is (5,17), respectively, and our m is -3.
Therefore, our slope is -3.
Our answer is B.
Answer:
you're not doing anything wrong
Step-by-step explanation:
In order for cos⁻¹ to be a function, its range must be restricted to [0, π]. The cosine value that is its argument is cos(-4π/3) = -1/2. You have properly identified cos⁻¹(-1/2) to be 2π/3.

Cos and cos⁻¹ are conceptually inverse functions. Hence, conceptually, cos⁻¹(cos(x)) = x, regardless of the value of x. The expected answer here may be -4π/3.
As we discussed above, that would be incorrect. Cos⁻¹ cannot produce output values in the range [-π, -2π] unless it is specifically defined to do so. That would be an unusual definition of cos⁻¹. Nothing in the problem statement suggests anything other than the usual definition of cos⁻¹ applies.

This is a good one to discuss with your teacher.
So when you add 8 plus 2 that is 10 and so when you add 80 with 20 you get 100 all u have to do is add those two 0's to get 100
