Answer:

(2, 1)

Step-by-step explanation:

In a reflection across the x-axis, the x coordinate will stay the same but the y coordinate will be the negative version of the original number.

This means (2, -1) will change to (2, 1)

Using dimensional analysis, what unit of time will make the statement true?

frosja888 [35]

The unit of time that will make the statement true is "day"

<h3>What unit of time will make the statement true?</h3>

The conversion equation is given as:

Seconds + Seconds/? * day = seconds

Represent the blank with a variable (x)

So, we have:

Seconds + Seconds/x * day = seconds

Subtract "seconds" from both sides of the equation

So, we have:

Seconds/x * day = seconds

Divide both sides of the equation by "seconds"

So, we have:

1/x * day = 1

Multiply both sides by x

x= day

Hence, the unit of time that will make the statement true is "day"
