Answer:

x = \frac{y-4}{7}

Step-by-step explanation:

Given

y = 7x + 4 ( subtract 4 from both sides )

y - 4 = 7x ( divide both sides by 7 )

\frac{y-4}{7} = x

Answer:

x = (y - 4)/7

Step-by-step explanation:

Subtract 4 from both sides to get:

y - 4 = 7x

Then, divide both sides by 7 to get:

(y - 4)/7 = x

Order: give Ceclor (cefaclor) 250 mg PO every 8 hours.
irinina [24]

Hello!

The answer is: 15 mL

Why?

From the statement we have that 250 mg need to be given every 8 hours, we can calculate how many mg will be given each day (24 hours):

\frac{24Hours}{8Hours} = 3

So,

3*250mg=750mg a day

We also know that there are 50 mg cefaclor every 1mL,

So, to know how many mL will be given with 750mg, we just need to divide it by 50

\frac{750}{50} = 15

Therefore,

15mL or 750 mg of cefaclor will be given each day.

Have a nice day!

Write an equation in standard form of the line passing through the points (3,3) and (-3,5)
Korvikt [17]

Answer:

The equation of line AB  with points (3,3) and (-3,5) is given as

: x + 3y = 12

Step-by-step explanation:

Here, the given points are A (3, 3) and B (-3,5).

Now, slope of any line is given as :

m = \frac{y_2 - y_1}{x_2 - x_1}

or, m = \frac{5-3}{-3 - 3}   = \frac{2}{-6}  = -\frac{1}{3}

Hence, the slope of the line AB is (-1/3)

Now , A POINT SLOPE FORM of an equation is

(y - y0)  = m (x - x0) ; (x0, y0)  is any arbitrary point on line.

So, for the point (3,3) the equation of the line is

y - 3y-3 = -\frac{1}{3} (x-3)   \implies 3y - 9 = 3 -x

Hence, the equation of line AB  with points (3,3) and (-3,5) is given as:

x + 3y = 12
