Answer:

f(n)=-3n+24

Step-by-step explanation:

A=(1,21)

B=(3,15)

slope:- Δy/Δx=21-15/1-3=6/-2= -3

Equation:-

y-y1=m(x-x1)

y-21=-3(x-1)

⇒y=-21=-3n+3

→ y= -3n+3

<u>y= -3n+24</u>

The cost of pumpkin seeds is proportional to
zheka24 [161]

Answer:

Part 1) The unit rate is  \$0.25\ per\ ounce

Part 2) A 56 ounce bag of pumpkin  Seeds cost $14.00

Step-by-step explanation:

Part 1) What is the unit rate  for the pumpkin seeds?

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

Let

y ----> the cost of pumpkin seeds in dollars

x ---> the weight in ounces

we have

For x=24 ounces, y=$6

Find the value of the constant of proportionality k

k=\frac{y}{x}

substitute the values

k=\frac{6}{24}=\$0.25\ per\ ounce

The unit rate is the same that the constant of proportionality k

therefore

The unit rate is

\$0.25\ per\ ounce

Part 2) How much would 56. ounce bag of pumpkin seeds cost?

we know that

The linear equation is equal to

y=0.25x

For x=56 ounces

substitute in the linear equation and solve for y

y=0.25(56)=\$14.00

How many solutions does 2.3y+3.2-y=2.1+1.3y+1.1 have?
jeka57 [31]
1.3y +3.2 = 1.3y +3.2

we notice that both sides of the equation are identical. So substitute y with any value and the equation would still be correct.

y has infinite solutions.

1. What is the slope of the line tangent to the curve defined by y2 + xy - x2 = 11x at the point (2, 3)?
andreyandreev [35.5K]

Step-by-step explanation:

By using Implicit Differentiation,

d/dx (y² + xy - x²) = d/dx (11x)

d/dx (y²) + d/dx (xy) - d/dx (x²) = 11

2y * dy/dx + x * dy/dx + y - 2x = 11

dy/dx (2y + x) = 11 + 2x - y

dy/dx = (11 + 2x - y) / (2y + x).

At the point (2, 3), we have x = 2, y = 3.

=> dy/dx = (11 + 2(2) - (3)) / (2(3) + (2))

= 12 / 8 = 1.5.

P.S. Your question is weird because (2,3) is not on the graph, let me know what is the correct question thanks!
