Answer:
y=-3x+4
Step-by-step explanation:
the equation for a line: y=mx+b
m stands for slope
b stands for the y-intercept
the slope is -3 because
1. the line is negative so it has a negative sign
2. from points (1,1) and (0,4) you go up 3 and over 1
m/slope= rise over run or rise/run
the y-intercept is 4 because
1. when the line reaches 0 on the x-axis that's where you find the intercept
2. you can use the graph and go to y-axis line and see that is goes through the point (0,4)

Answer: 120
Step-by-step explanation:
If you want the explanation tell me in the comments.
Y= -2x² + 32x -12
Take the derivative, and set it equal to zero. We are finding where the slope equals zero (the peak of the parabola)
y'= -4x + 32
0 = -4x + 32
4x=32
x=8
The maximum is at the point x=8. Plugging into the original equation:
y= -2x² + 32x -12
y= -2(8)² + 32(8) -12
y= 116
The maximum is at point y=116
Keep in mind what maximum means. It is the largest value for y that the function has. That means that the range, or all possible y-values, is
y ≤ 116.
Therefore, the answer is A) Max: 116, range: y ≤ 116
812*0.073= the cost would be 59.276$. and I'm good with math if u need further help
Hope this helps
