Answer:
-73
Step-by-step explanation:
if f is 73
and they made f negative, they just made 73 negative too.
i don't know if there is more in that expression
all i can see is
-f=___
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
x= 1, y= -4
We conclude that Michael worked for a total of 11.46 hours in the weekend.
<h3>How much time did he work on the weekend?</h3>
We know that during the weekend, the times that he used for each task are:
- (6 + 3/7) hours to do his homework.
- 4.37 hours to clean his room.
- 2/3 hours to walk the dog
The total time is given by the sum between the above numbers, where the difficulty is the fact that the 3 numbers are in different notations (decimal, fraction, and mixed).
The sum is:
S = (6 + 3/7) h + 4.37 h + 2/3 h
The easier way to do this, is to write the 3 numbers in decimal form:
2/3 = 0.66
6 + 3/7 = 6 + 0.43 = 6.43
Then the total time is:
S = 6.43 h + 4.37h + 0.66h = 11.46 h
We conclude that Michael worked for a total of 11.46 hours in the weekend.

We have to write the point-slope equation of the line.
The point is (4,-2) and the slope has to be calculated.
We need another point to calculate the slope. We see that the y-intercept is y = 6, so another point of the line is (0, 6).
We then can calculate the slope with the points (0,6) and (4,-2):
Now that we have the slope m = -2 and the point (4,-2), we can write the equation as:
Answer: y + 2 = -2(x - 4)
