Answer: Paula starts with 301.5 yarns.
Step-by-step explanation:
Equation of a line passing through two points (a,b) and (c,d) is given by:-

Given: x= number of square inches knitted on the scarf
y= number of yarns remaining on the ball of yarn
The equation of a line passing through (15, 300.2) and (26, 177.88):

To find initial point, put x=0

Hence, Paula starts with 301.5 yarns.
Answer: If solving for P it is p = -3/5
If you are just wanting the equation it is 5p+3
Step-by-step explanation: Plug in c and d into 5p+cd
You get 5p+(1/5)(15)
Once done with the math it is 5p+3
Answer:
arc AC = 111°
Step-by-step explanation:
∠APC is a central angle, so arc AC is equal to the measure of ∠APC.
∠APC and ∠BPC are supplementary. So, m∠APC + m∠BPC = 180
m∠APC + 69 = 180
m∠APC = 111
arc AC = 111°
So start with the top one and end w the bottom
Here you go, hope I helped.
