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 value of a piece of land deprecates at a rate of 0.60 per year after three years land is worth 2500 what was the original va
Setler79 [48]

Well, there is actually a formula for this kind of exercises:

n is the price the land had in the third year year

2500=n-nx0.6

2500=n(1-0.6)

2500=nx0.4

n=2500:0.4

n=6250

m is the price the land had in the second year

6250=m-mx0.6

6250=m(1-0.6)

6250=nx0.4

p=6250:0.4

p=15625

p is the price the land had in the first year

15625=p-px0.6

15625=p(1-0.6)

15625=px0.4

p=15625:0.4

p=39,062.5 <- this should be your answer. Hope this helps.

The equation x^2 + y^2 + 21 = 40 + 18y. What is the radius of this cookie?​
trapecia [35]

Answer:

The radius is 10

Step-by-step explanation:

Given

x^2 + y^2 + 21 = 40 + 18y.

Required

The radius

Rewrite as:

x^2 + y^2 - 18y = 40-21

Subtract 81 from both sides

x^2 + y^2 - 18y +81= 40-21+81

Expand

x^2 + y^2 - 9y - 9y +81= 40-21+81

Factorize

x^2 + y( y- 9) - 9(y -9)= 40-21+81

Factor out y - 9

x^2 + (y- 9) (y -9)= 40-21+81

Express as squares

x^2 + (y- 9)^2= 100

x^2 + (y- 9)= 10^2

The equation of a circle is:

(x - a)^2 + (y- b)= r^2

By comparison:

r^2=10^2

r = 10
