After 2 hours, there are 1,400 mL of fluids remaining in a patient’s IV. The fluids drip at a rate of 300 mL per hour. Let x be

CaHeK987 [17]

Answer:

$y(2) = 1400$

Using this condition we got:

$1400= -300*2 +b$

And solving for b we got:

$b= 1400+ 600= 2000$

So then our linear function is given by:

$y = -300x +2000$

Where y is the amount of fluid left and x the number of hours ellapsing

Step-by-step explanation:

We want to set up a linear function like this one:

$y = mx+b$

Where y is the amount of fluid left, m the slope and b the initial amount. From the info given we know thatm = -300. And we also have the following condition:

$y(2) = 1400$

Using this condition we got:

$1400= -300*2 +b$

And solving for b we got:

$b= 1400+ 600= 2000$

So then our linear function is given by:

$y = -300x +2000$

Where y is the amount of fluid left and x the number of hours ellapsing

the balance in your checking account is $962. you write checks for $39, $56 and $138. you then deposit $117 from your paycheck.

iVinArrow [24]

962-39=923 so your balance would be $846
923-56=867
867-138=729
729+117=846

∠DFG and ∠JKL are complementary angles. m∠DFG = x + 5, and m∠JKL = x − 1. Find the measure of each angle.

Nonamiya [84]

Complimentary angles, when added, will equal 90 degrees
so < DFG and < JKL, when added = 90
x + 5 + x - 1 = 90
2x + 4 = 90
2x = 90 - 4
2x = 86
x = 86/2
x = 43

< DFG = x + 5......43 + 5 = 48 degrees <==
< JKL = x - 1........43 - 1 = 42 degrees <==

Tyna simplified the expression 3x^3/12x^-2 to x/4. What was Tyna’s mistake?

Ksenya-84 [330]

We are given expression: $\frac{3x^3}{12x^{-2}}$ .
