Answer:

  B, D

Step-by-step explanation:

In dollars per hour, the rates are ...

  A. $1200/(48 h) = $25/h

  B. $500/(50 h) = $10/h

  C. $750/(25 h) = $30/h

  D. $1500/(150 h) = $10/h . . . . matches B

  E. $800/(40 h) = $20/h

Choices B and D are the same, at $10/hour.

What is the x-intercept of the graph?
Umnica [9.8K]

Answer: (6,0)

Step-by-step explanation: To find the x-intercept, we plug a 0 in for y.

So we have 2x - 3(0) = 12.

Simplifying from here, we have 2x = 12.

Now divide both sides by 2 and we get <em>x = 6</em>.

So our x-intercept is 6.

This means that our line crosses the x-axis 6

units to the right of the origin or at the point (6,0).

What is the domain of the function y = 2 StartRoot x minus 5 EndRoot?
Juli2301 [7.4K]

Answer:

The domain of the function should be:

'x greater than or equal to negative -5'.

Hence, option A is true.

Step-by-step explanation:

Given the expression

2\sqrt{x-5}

The domain of a function is the set of input or arguments for which the function is real and defined

We know that the value, inside the radicand, is the number found inside a radical symbol which must be greater than 0, otherwise, it would make the function undefined,

i.e.

x-5 ≥ 0

x ≥ 5

In other words, the domain of the function should be:

'x greater than or equal to negative -5'.

Therefore, the domain of the function:

x ≥ 5

\mathrm{Domain\:of\:}\:2\sqrt{x-5}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:5\:\\ \:\mathrm{Interval\:Notation:}&\:[5,\:\infty \:)\end{bmatrix}

Hence, option A is true.

What are the possible values of x for the following functions?
stiks02 [169]
What can a denominator never be?

0

so, we need to figure what x can't be... the only way to multiply 2 things together to get 0 is if one or both are zero.

so, what x values make our denominator 0?

to figure this out, we need to set (x-1)(x-2)=0

now we split and solve.

x - 1 = 0 \\ x - 2 = 0
so when x is 1 or 2 the function doesnt make sense.

but, x can be every other number and it does, so the answer is
