When a line and a curve are tangent to each other, they are joined together by 1 point (x,y). So, you equate both equations either in terms of x or y. For this problem, let's equate in terms of y.

y = k - x
y = x² + 3x + 1

k - x = x² + 3x + 1
k = x² + 3x + x + 1
k = x² + 4x + 1

This would be the value of k. Since we are not given the common point, it can only be expressed in terms of x or y.

an old book listed that $72$ turkeys were bought for $\$\square.\square\square$ each, at a total cost of $\$\square 67.9\square.
Westkost [7]

The cost of each turkey, if each is a smudge that represents some unreadable digit is $0.94

<h3>Cost of each turkey</h3><h3 />
  • Total number of turkey bought = 72
  • Total cost = $67.9

Cost of each turkey = Total cost / Total number of turkey bought

= 67.9 / 72

= 0.943055555555555

Approximately,

Cost of each turkey = $0.94

Therefore, the cost of each turkey, if each is a smudge that represents some unreadable digit is $0.94
