Answer:
y=4x-1
Step-by-step explanation:
Slope-intercept form is written in y=mx+b
*m=slope
*b=y-intercept
From what I see,
the line hits the points (0,-1) and (1,3)
Slope is the rise (change in the y-coordinate) of the line divided by the run (change in the x-coordinate).
4÷1=4
Slope=4
y=4x+b now
The y-intercept is the value of y when the line meets the y-axis
It seems to meet at (0,-1)
So we end up with...
y=4x-1 as our equation
Given :
Zach wants to make a profit of more than 300 for painting 4 identical too rooms.
The cost of supplies is 32.50 for each room.
To Find :
Which inequality and solution represent the dollar amount n, that zack must be paid for each room, if he is to make a profit more than $300.
Solution :
Profit is given by :
Profit = S.P - C.P
Now, it is given that profit > 300 .
Profit = S.P - C.P > 300

Hence, this is the required solution.
Answer: A- Selena is incorrect because she should have substituted the values for the variables first, and then simplifed
i just took the test. i know that drake is correct because his finale answer was -1/2 and Selenas finale answer was 1/2 if she would have substituted her vaules before simplifying she would have gotten the answer 1/-2 instead of -1/-2 which resulted in her finale answer to be 1/2
The answer would be 50 + 13 = 63
