1. A patient is told to force fluids to 3 L/day. How many mls should she drink?

Damm [24]

The patient should drink 3000 milliliter per day

Solution:

Given that a patient is told to force fluids to 3 liter per day

To find: Amount the patient should drink in milliliter

Use the conversion factor,

1 liter = 1000 milliliter

Now we have to find the amount the patient she drink in milliliter

Amount patient drinks in liter = 3 liter per day

Therefore, convert 3 liter to milliliter

3 liter = 1000 x 3 milliliter = 3000 milliliter

Thus the patient should drink 3000 milliliter per day

A linear function is parallel to the line y= 4x + 8 and also goes through the point (2,15).What is the linear equation for this

horrorfan [7]

When written in the $y=mx+q$ form, the slope of a line is given by the coefficient $m$ . Moreover, two lines are parallel if the have the same slope.

Now, the slope of the known line is 4, so our line's slope will be four as well.

In general, when you know the slope $m$ of a line and one of its points $(x_0,y_0)$ , the equation of the line can be derived from the following formula:

$y-y_0 = m(x-x_0)$

Which in your case becomes

$y-15 = 4(x-2)$

Expand the right hand side and solve for y:

$y = 4x+7$
