Answer:

$42.88

Step-by-step explanation:

Let's create a proportion using the following setup:

cost/pounds=cost/pounds

We know that it costs $20.42 for a 10 pound turkey.

$20.42/10 pounds= cost/pounds

We don't know how much a 21 pound turkey costs, so we can say that it costs $x for a 21 pound turkey.

$20.42/ 10 pounds= $x/ 21 pounds

20.42/10=x/21

We want to find x, by getting x by itself.

x is being divided by 21. The inverse of division is multiplication. Multiply both sides by 21.

21*(20.42/10)=(x/21)*21

21* 20.42/10=x

21*2.042=x

42.882=x

Round to the nearest cent, or hundredth.

42.88=x

x= $42.88

A 21 pound turkey costs $42.88

The length of a rectangle is given by L=3y + 4x while the width is
Wittaler [7]

Answer:

21y² +34 yx + 8x²

Step-by-step explanation:

Area of a rectangle is given by L×W where L is length, and W is width

Given L=3y+4x

          W=7y+2x

Area= (3y+4x) × (7y+2x)

          3y(7y+2x) + 4x(7y+2x)

           21y² + 6yx +28yx+8x²

            21y² +34 yx + 8x²

Write an equation for the line in point slope form that passes thru (1,-4) and (3,2)
Nimfa-mama [501]

Answer:

  y+4 = 3(x -1)

Step-by-step explanation:

You are given two points, so you only need to find the slope. The slope is given by the formula ...

  m = (y2 -y1)/(x2 -x1)

  m = (2 -(-4))/(3 -1) = 6/2 = 3

The point-slope equation for a line is ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

Using the first point, the equation is ...

  y+4 = 3(x -1)
