If K is the midpoint of JL, JK = 9x -1 and KL = 2x +27, find JL
Liula [17]

Answer:

JL = 70

Step-by-step explanation:

Since K is the midpoint of JL then JK = KL and

JL = JK + KL = 9x - 1 + 2x + 27 = 11x + 26

solve for x using JK = KL

9x - 1 = 2x + 27 ( subtract 2x from both sides )

7x - 1 = 27 ( add 1 to both sides )

7x = 28 ( divide both sides by 7 )

x = 4, hence

JL = 11x + 26 = (11 × 4 ) + 26 = 44 + 26 = 70

The scale of a map is 1 inch : 10 miles. What is the scale of the map area to the actual area? 1 in. : 10 mi 1 in. : 20 mi 1 in.
AlexFokin [52]

Answer:

1 in. : 100 mi

Step-by-step explanation:

Scale = 1 inch : 10 miles

In the scale, the quantity is Length

The relationship between length and Area is;

Area = Length * Length

So inch becomes inch^2

1 inch * 1 inch = 1 i

10 miles * 10 miles = 100

The correct option is;

1 in. : 100 mi

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
