X = k/y
4 = k/10
k = 4 x 10 = 40
Thus, x = 40 / y
90 = 40 / y
y = 40/90 = 4/9
The number 12 and 14 are the modes .
Answer:
200
Step-by-step explanation:
Let market price = y
According to question
160+20% of y=y
160+20/100y=y
160=y-20/100y
160=100/100y-20/100y
160=80/100y
160×100/80=y
y=200

Answer:
Slope: 10
Y-intercept= 30
Step-by-step explanation:
y= mx + b
m = slope
b = y-intercept
y= 10x + 30
Slope: 10
Y-intercept= 30
