Answer:

y=2x-3

Step-by-step explanation:

Since we know that the slope-intercept form is y=mx+b, we can plug in the formula with what we already know to find b!

In the coordinates (2,1):

2 is the x
1 is the y

Now, we will plug these numbers in:

1=2*2+b

1=4+b

b=-3

Now we can rewrite the equation since we found b:

y=2x-3

Hope this helped! :)

5 is a greater than symbol >
7 is 1/3 and negative 1/3 so -1/3
8 is 14 and -14
9 is 21 and -21

<h2>♨ANSWER♥</h2>

Child labor is a service rendered by children in any field during their childhood. This is done due to lack of resources for subsistence, irresponsibility of the parents or lack of resources by the owner to increase their returns on low investment.

This does not matter with the cause of child labor as all the reasons force children to live life without childhood. Childhood is the greatest and happiest period of everyone’s life, during which one learns about the basic strategy of life from parents, loved ones and nature. Child labor interferes with the proper growth and development of children in all aspects, mentally, physically, socially and intellectually.

Kenya plans to make a down payment plus monthly payments in order to buy a motorcycle. At one dealer

m_a_m_a [10]

Answer:

After 20 months the total amount paid would be same for both

The amount is $5500

Step-by-step explanation:

* Lets explain how to solve the problem

- Kenya plans to make a down payment plus monthly payments in

order to buy a motorcycle

- There are two dealer

# 1st : she would pay $2,500 down and $150 each month

# 2nd : she would pay $3,000 down and $125 each month

- We need to know after how many months the total amount paid

would be the same for both dealers

* Lets change the two dealer to two equations

- Let f(x) represents the total amount of the motorcycle in x months

∴ f(x) = 2500 + 150 x ⇒ 1st dealer

∴ f(x) = 3000 + 125 x ⇒ 2nd dealer

- Equate the two equations

∴ 2500 + 150 x = 3000 + 125 x

- Subtract 125 x from both sides and 2500 from both sides

∴ 150 x - 125 x = 3000 - 2500

∴ 25 x = 500

- Divide both sides by 25

∴ x = 20

* After 20 months the total amount paid would be same for both

- To find the amount substitute the value of x in one of the

two equation

∵ f(x) = 2500 + 150 x

∵ x = 20

∴ f(x) = 2500 + 150 (20)

∴ f(x) = 2500 + 3000

∴ f(x) = 5500

∵ f(x) represents the total amount of the motorcycle

* The amount is $5500
