Profit = revenue - expenses
P = 5c - 39 <== ur equation
x < = 40
ur independent variable is c, the number of cars
ur dependent variable is p, ur profit
yes, this relationship is a function because for each value of c there is a unique value of p
ur domain (ur c values) will be : 0 < = c < = 40
ur range (ur p values) will be -39 < = p < = 161
Answer:
y-2=2(x-12)
the alternative is
y+3=2(x-2)
Step-by-step explanation:
All you would have to do is put the numbers on a number line like -2 in the spot on the number line that says -2 and 1 in the spot on the number line that says 1 and the same for every other number this is because an integer is any whole number.
Answer:
-32

Complete question :
a researcher compared the Heights and shoe sizes for 50 men, selected at random. The equation shown describes a line of best fit for the data, where X is the shoe size and y is the height, in inches (y=1.6x + 58)
Based on the equation, what is the approximate shoe size for a man having a height of 60 inches
Answer:
1.25
Step-by-step explanation:
Given the regression equation :
y=1.6x + 58
X = shoe size ; y = height
Using the equation, the approximate shoe size of a man with a height of 60 will be ;
60 = 1.6x + 58
60 - 58 = 1.6x
2 = 1.6x
2/1.6 = 1.6x / 1.6
x = 2 / 1.6
x = 1.25
Hence, approximate shoe size of a man with a height of 60 will be 1.25
