Answer:
20 quarts of peanut oil worth 19 cents a quart must be mixed.
Step-by-step explanation:
So basically, the first question after the word problem is asking you to write an equation to represent the value of Mama's car after a certain amount of years (t). Since the value of her car decreases by 3% each year, you could multiply 3% by the original value of her car, to find what 3% is, OR you could subtract 19,400 (the value of her car after 1 year) from 20,000 INSTEAD of multiplying 20,000 by 3%.
Equation: value=20,000 - 600t
To answer the next question, just plug it into the equation you created.
500<20,000 - 600t
-19500< -600t
32.5>t
Final Answer: It would take at least 32 and 1/2 years for the value of Mama's car to be less than $500.

Answer:
j=-37
Step-by-step explanation:
step 1
Find the slope of the given line
we have
Convert to slope intercept form
Isolate the variable y
subtract 2x both sides
divide by 3 both sides
The slope is
step 2
we have the points
(2,-9) and (j,17)
Find the slope
The formula to calculate the slope between two points is equal to
substitute
Remember that
If two lines are parallel then their slope are equal
therefore
