is more than 1/2 so he painted more than 1/2 of his house
Answer:
T depends on what y equals. -1/4y, i guess
Step-by-step explanation:
Answer:
Slope: 
Equation: 
Step-by-step explanation:
The line of the best fit passes through the points (0,8) and (4,6).
If the line passes through the points
and
then the slope of the line is

Hence, the slope of the line of the best fit is

The equation of the line is

where m is the slope and b is y-intercept, so the equation of the line of the best fit is

Answer:
f^-1(x) = 3 - 5x, second option
Step-by-step explanation:
To determine the inverse simply interchange the variables and solve for y;
f(x) = 3 - x / 5 -> Interchange the variables
x = 3 - y/5 -> Multiply either side by 5
5x = 3 - y -> Subtract three from either side
- y = 5x - 3 -> Divide either side by - 1
y = - 5x + 3
Your solution is f^-1(x) = 3 - 5x
The function that best represents the data is y = 0.75x + 4.5. The slope in this case represents the increase in the amount she spends in $ due to the number of cards she makes. The intercept with the Y axis (4.5) means that she has an expense of 4.5 $ without having made any card yet.
