Answer:

Only choices B and C are correct.

Step-by-step explanation:

The square root parent function is $f(x)= \sqrt{x}.$

The function $f(x)$ is not a linear function, therefore it's graph cannot be a straight line. This rules out choice A.

The function $f(x)$ is defined at $x=0$ because $f(0)= \sqrt{0} =0$ . This means that choice B is correct.

The function $f(x)$ is only real for values $x\geq 0$ , because negative values of $x$ give complex values for $f(x)$ . This means that choice C is correct.

The function $f(x)$ can take only positive values which means it is confined to only the I quadrant, and is not defined in quadrants II, III, and IV. This rules out Choice D.

Therefore only choices B and C are correct.

Solve the inequality –1 > –2(x – 4) – 5(4x – 7).

Ksivusya [100]

Answer:

$x > 2$

Step-by-step explanation:

$–1 > –2(x – 4) – 5(4x – 7)$

$–1 > –2x + 8 –20x + 35$

$–1 > - 22x + 43$

$- 1 - 43 > - 22x$

$- 44 > - 22x$

$\frac{ - 44}{ - 22} < \frac{ - 22x}{ - 22}$

$2 < x$

$x > 2$

a satelite moves at the speed of 27,000 kilometers per hour what 4 number could be the actually speed of the satelite

Anvisha [2.4K]

If the satellite moves at a speed of 27,000 km p/h, your answer depends on the question.

This could be written in an algebraic expression, such as:

27,000x = S [for S stands for the ultimate speed of the satellite]

Of course, if this is a 3rd grade level question, I highly doubt they have even gotten started to including the alphabet into math.

So, I would suggest plugging 4 into X.
To explain this to her, just say that the speed needs to be multiplied by the amount of hours it has traveled. (I got 4 because there is a '4' in the question instead of 'for').

Meaning,
27,000 x 4 = 108,000 km per 4 hours

If her teacher decides to ask why that number, have her explain the question did not make sense so she plugged in a 4 to find an answer to a certain amount of hours.

Hope that helps a bit with the confusion!
