Step-by-step explanation:
The new mixture exists 56.5% peanuts.
<h3>How to estimate the total number of peanuts required for the mixture?</h3>
The first batch of 9 lb of mixed nuts possesses 40% peanuts.
This means the quantity of peanuts exists:
9 40/100 = 3.6 lb
The second batch of 9 lb of mixed nuts possesses 73% peanuts.
This means the quantity of peanuts exists:
9 73/100 = 6.57 lb
The total quantity of peanuts in the mix exists
3.6 lb + 6.57 lb = 10.17 lb
There exist 9 lb + 9 lb = 18 lb of mix.
Therefore, the percent of peanuts in the mix exists:
10.17 / 18 100 = 56.5%
The new mixture exists 56.5% peanuts.

Answer:
Assign variables to the coordinates of the given points
Let the coordinates of P be (x1;y1) and Q(x2;y2)
x1=−1;y1=−5;x2=5;y2=4
Write down the two-point form of the straight line equation
y−y1x−x1=y2−y1x2−x1
Substitute the values and make y the subject of the equation
y−(−5)x−(−1)y+5x+1y+5y+5y=4−(−5)5−(−1)=96=32(x+1)=32x+32=32x−72
Write the final answer
y=32x−312
