Answer:

f(-4) = -18

Step-by-step explanation:

f(-4)  means x = - 4

So Plug in x = - 4 into f(x) = 3x - 6

f(-4) = 3(-4) - 6

= -12 - 6

= -18

So

f(-4) = -18

Answer:

D. -18

Step-by-step explanation:

f(-4)=3(-4)-6        Substitute -4 for 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!

Which of the following graphs are identical
Lady bird [3.3K]

Answer:

The domain is x ≥ -7

Step-by-step explanation:

The domain asks what values can x take

We know that the sqrt(x+7) must be ≥ 0

That means the smallest value it can be is zero

x+7 ≥ 0

x ≥ -7

The domain is x ≥ -7

A. 352 seconds or 5 minutes 52 seconds.
B. 320 seconds or 5 minutes and 20 seconds  
C. 27687 steps
There are 5280 feet per mile. In A, 3 strides per second at 5 feet gives us 15 ft per second. 5280/15 = 352 seconds. In B, 3 strides per second at 5.5 feet gives us 16.5 feet per second. 5280/16.5 = 320 seconds. In C, we calculate the total feet to divide by 5 per step. multiply 26 miles by 5280 to get feet per mile and multiply 385 by 3 to get the feet per yard. Add them together. then divide by 5. 26(5280) + 385(3) =138435. 138435/5 = 27687 steps

In an 18-meter race between a tortoise and a hare, the tortoise leaves 23 minutes before the hare. The hare, by running at an av
seropon [69]
We know that:
time=distance/speed
if the tortoise speed is x m/min, then since 0.5 m/hr=1/120 m/min
18/x=23+18/(x+1/120)
solving for x we get:
x=0.08 m/min
speed of hare is:
(0.08+1/120)=0.088 m/min
