Answer:

D. x>7

Step-by-step explanation:

Multiply - and -3

x+3>10

Subtract 3 on both sides

x>7

(Remember you can only switch the symbol if you divide or multiply by negative it does not apply on addition or subtraction)

Hope this helps!

Answer:

It is D.

Step-by-step explanation:

Remove parentheses: x + 3 > 10

Subtract 3 from both sides: x > 10 - 3

Simplify 10 - 3 to 7: x > 7

ANSWER

C. The left end goes up; the right end goes down.

EXPLANATION

The given function is

f(x) =  - 2( {x - 2)}^{5}

We analyze the end behavior of this function using the leading term.

The leading term of this function is:

- 2 {x}^{5}

Since the degree(5) is odd and the leading coefficient (-2) is negative, the graph rises on the left and falls on the right.

In other words, the left end of the graph goes up and the right end goes down.

The correct option is C.

Can someone please explain this problem to me idk what I am doing wrong and can you draw the problem for me thanks
Bogdan [553]

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.
