KL = 2x + 2
JL = 55, and
JK = 7* +8,
Find KL.
J
K
L

Answers

Answer:

KL = 12

Step-by-step explanation:

JK + KL = JL

where:

JK = 7x + 8

KL = 2x + 2

JL = 55

plugin values into the equation:

7x + 8 + 2x + 2 = 55

7x + 2x = 55 - 8 - 2

9x = 45

x = 45 / 9

x = 5

KL = 2x + 2

KL = 2(5) + 2

KL = 12

Jerry planted a pine tree that was 5 feet tall and a maple tree that was 10 feet tall. The pine tree grew 3 feet taller per year and the maple tree grew 2 feet taller per year. Which comparison is described by the inequality below? After x years, the pine tree is taller than the maple tree. After x years, the pine tree is at least as tall as the maple tree. After 3x years, the pine tree is taller than the maple tree was after 2x years. After 3x years, the pine tree is at least as tall as the maple tree was after 2x years.

Answers

The initial length of the pine tree=5 feet.

Groth rate of pine tree =3 feet/year.

The initial length of the pine tree =10 feet.

Groth rate of the maple tree =2 feet/year.

After x years, the height of the pine tree= 5+3x feet and

after x years, the height of the maple tree= 10+2x feet.

The inequality for which, after x year, the pine tree is taller than the maple tree is

[tex]5+3x>10+2x[/tex]

[tex]\Rightarrow x>5[/tex] .

The inequality for which, the pine tree is at least as tall as the maple tree is [tex]5+3x\geq10+2x[/tex].

[tex]\Rightarrow x\geq 5[/tex] .

Again, after 3x years, the height of the pine tree= 5+3(3x)=5+9x feet and

after 2x years, the height of the maple tree= 10+2(2x)=10+4x feet.

The inequality for which, after 3x years, the pine tree is taller than the maple tree was after 2x years is

[tex]5+9x>10+4x[/tex]

[tex]\Rightarrow 5x>5[/tex]

[tex]\Rightarrow x>1.[/tex]

The inequality for which, the pine tree is at least as tall as the maple tree is [tex]5+9x\geq10+4x[/tex].

[tex]\Rightarrow 5x\geq5[/tex]

[tex]\Rightarrow x\geq 1.[/tex]

A rectangle has twice the area of a square. The rectangle has the dimensions of 20 inches by 8
inches. What is the perimeter of the square. SHOW WORK PLEASE

Answers

Answer:

In order to calculate perimeter, you need to add together the lengths of all four sides of the square. You are given the length of one side. Remember, all sides of a square are equal, so really you already have the measures of each side. Then, you add them together, so 6 + 6 + 6 + 6 = 24 inches.

Step-by-step explanation:

The perimeter of the square is 24

Write an equation of the line that passes through (1, 2) and is perpendicular to the line y = 1/3x+4. An equation of the perpendicular line is
y = ?

Answers

Answer:

I'm not sure but I believe its y=-3x+5

Step-by-step explanation:

You start off by finding slope which is -1/m. So 1/1/3=-3. From here you plug in the variables (1,2) and solving. The equation becomes y=-3x+b. From here plug in x and y. So, 2=-3+b. From here add 3 to both sides and you get 5=b. Then just put it together. y= -3x+5

A. Write and equations to represent the number of minutes use in a month that will make the plans cost the same?

B. Solbe the equation to find the number of minutes
_________________________________________________________________
3. cell phone plan costs per month for unlimited calling plus $0.15 per text message.

A. write a linear model that represents the monthly cost of this cell phone plan if the user sends t text messages

b. if you send 200 text messages, how much would you pay according to this cell phone plan?

Answers

Answer:

for the first one the answer is 28-9=18 and 30-13=17 are not the same but are close and for the second one the answer is $30 for the phone plan cause 200×0.15=30

If you use 50 minutes in a month, both plans will cost $32.50.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

2.

A. Let x be the number of minutes used in a month. Then, the cost of Plan A is given by:

Cost(A) = 0.09x + 28

The cost of Plan B is given by:

Cost(B) = 0.13x + 30

To find the number of minutes that will make the plans cost the same, we need to set Cost(A) equal to Cost(B) and solve for x:

0.09x + 28 = 0.13x + 30

0.04x = 2

x = 50

Therefore, the plans will cost the same if you use 50 minutes in a month.

B. If you use 50 minutes in a month, the cost of Plan A will be:

Cost(A) = 0.09(50) + 28 = 32.50

The cost of Plan B will also be:

Cost(B) = 0.13(50) + 30 = 36.50

Therefore, if you use 50 minutes in a month, both plans will cost $32.50.

3.

A. Let C be the monthly cost and t be the number of text messages sent. Then, the linear model that represents the monthly cost is:

C = 0.15t + base cost

The base cost is the cost for unlimited calling, which is not specified in the problem.

B. If you send 200 text messages, the monthly cost will be:

C = 0.15(200) + base cost

C = 30 + base cost

The total cost will depend on the base cost for unlimited calling.
