3.)y= 2x + 1
4.)y= -2/3x + 1
The structure of the formula is y = mx + b.
m is the slope.
slope is found by rise over run.
b is the y intercept.
which is found by where the line is on the y axis

How much does a chicken cost and duck?
Firdavs [7]

Answer:

Chicken is $8

Duck is $5

Step-by-step explanation:

Step 1: Let x represent the cost of chickens and let y represent the cost ducks. Since we have two unknowns, we need two equations to find them.

Step 2: The total cost of chickens Michael sold last month can be shown as 50x, and the total cost of ducks he sold last month can beshown as 30y Since these together add up to 550, we get these equations:

50x+30y = 550

We are also given that this month, Michael sold 44 chickens, and 36start text, 36 ducks, $532. This equaion can be expressed as:

44x+36y=532

Now that we have a system of the two equations, we can now go ahead and solve the two equations.

Step 3: We can now solve the system of equations by using the elimination method. Manipulate the equations so one of the variables has the same coefficients but with opposite signs.

-6*50x+(-6)*30y\\=-300x-180y\\=-6*550\\=-3300                  5*44x+5*36y\\=220x+180y\\=5*532\\=2660

Now eliminate y

-300x-180y=-3300\\+220x+180y=2660\\=-80x-0=-640

When we solve the resulting equation, we obtain that x=8. Then, we can substitute this into one of the original equations and solve for y to obtain y=5.

Step 4: Recall that x denotes the cost of a chicken and y denotes the cost of a duck. Therefore, a chicken costs $8, and a duck costs $5

Nooooow this is the story all about how my life got flipped turned upsidedown and id like to take a minute so sit right there and ill tell you how i became the prince of a town called Bel Air.

In west Philadelphia born and raised on the playground is where i spent most of my days. chillin out maxin relaxin all cool and all shootin some b-ball outside of the school

when a couple of guys, they were up to no good, started making trouble in my neighborhood. i got in one little fight and my mom got scared she said "youre moving with your auntie and uncle in bel air"

i begged and pleaded with her day after day, but she packed my suit case and sent me on my way. she gave me a kiss and then gave me my ticket i put my walkman on and said "i might as well kick it."

first class yo, this is bad drinkin orange juice outta champagne glass is this what the people of bel air be livin like? hmmm this might be alright. but wait i hear theyre prissy, bourgeois, all that. is this the type of that they just send this cool cat?

i dont think so, ill see when im there. i hope theyre prepared for the prince of bel air. well the plane landed and when i came out there was a dude who looked like a cop standing there with my name. i aint trying to get arrested yet i just got here i sprang with the quickness like lightning, disappeared.

i whistled for a cab and when it came near the license plate said fresh and it had dice in the mirror. if anything i could say that this cab was rare. but i thought "nah forget it- yo homes to bel air!"

i pulled up to a house about 7 or 8 and i yelled to the cabbie "yo homes smell ya later!" i looked up at my kingdom, i was finally there. to sit on my throne as the prince of bel air.
