For a linear function, you want it in y= mx + b form
They give you the slope your x, and when they say f(7)=1 that's like saying when x=7, y=1, or the ordered pair (7,1). To make it in y=mx+b, you can plug these coordinates in to solve for b. So, 1=7(7)+b, after you plug in slope and your point. Do math, 1=49+b, b=-48
That's how I think it's done
The pic is really faint. Plz make it eazier to see.
To find the perimeter of a triangle, you need to find the length of each side and add all of them to find the perimeter. To find the distance between two points you use the distance formula with d as the distance between two coordinates, (x1,y1) and (x2,y2). , Hope this helps.
Answer:
The cost of 1 small box of apples = $7.
Step-by-step explanation:
Let x be the cost of each small box of apples and y be cost of each large box of apples.
We have been given that in the morning he sells 3 small boxes and 14 large boxes for a total of $203. We can represent this information in an equation as:
We are also told that in the afternoon he sells 11 small boxes and 11 large boxes for a total of $220. We can represent this information in an equation as:
Now we will solve our system of equations using substitution method. From equation (1) we will get,
Upon substituting in equation (2) we will get,
Upon distributing 11 we will get,
Now let us have a common denominator on the left hand side of our equation.
Upon multiplying both sides both sides on our equation by 14 we will get,
Therefore, the farmer sells each each small box of apples for $7.
