Answer:
y = 2/5x + 1/5
Step-by-step explanation:
y - y1 = m(x - x1)
y - 1 = 2/5(x - (-3))
y - 1 = 2/5(x + 3)
y - 1 = 2/5x + 6/5
y = 2/5x + 6/5 - 5/5 (since 1 equals to 1/1, 2/2, 3/3, etc.)
y = 2/5x + 1/5
Answer:
b. $1 in price is associated with a decrease of $8,000 in sales
Step-by-step explanation:
Linear function:
A linear function has the following format:
In which m is the slope, which represents by how much y changes when x changes by 1.
ŷ = 50,000 − 8x
This means that , in thousands of dollars, so when the price x increases by 1, the sales will be decrease by $8,000, and thus, the correct answer is given by option b.
Step-by-step explanation:
Diameter = r × 2
Where r = 2m
D = 2×2 = 4m
C= (3.14) × 4
= 12.56
