Paula has a large ball of yarn that she is going to use to knit a scarf for the winter. every square inch on the scarf requires a certain number of yards of yarn from the ball. a linear model of this situation contains the values (12, 317.24) and (25, 164.75), where x represents the number of square inches knitted on the scarf, and y represents the number of yards remaining on the ball of yarn. how many yards of yarn did paula start with? a. 458 b. 481.99 c. 495

A

Step-by-step explanation:

To find where Paula started, find the rate of change or slope in order to work backwards.

This means -11.73 yards remaining on the ball for each inch knitted. The first point is at (12, 317.24) so work backwards 12 inches or 12*11.73 = 140.76.

This means it started at 317.24 + 140.76 = 458.

answer: the answer is 35%

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
