Answer:
To determine which equation has a maximum at y =5, you will need to compare their graphs looking only at the x-values between 0 and 27.
Step-by-step explanation:
A) 5/2x^3-9/4x^2+7/2x-3/2
b) the ans. are not the same.
Y=mx+b
y=2x+b
then substitute x and y
3=2(3) + b
3= 6 + b
b=-3
y=2x-3
I believe the answer is A. X-Coordinate
Answer:
First one: yes
Second one: yes
Third one: no
Step-by-step explanation:
To find the midpoint of a line segment, you take the x and y coordinates of the 2 points, add each of them up, and divide each of them by 2.
First one: x = (1+3)/2 = 2, y = (2+4)/2 = 3, so it's correct.
Second one: x = (-1+3)/2 = 1, y = (1+-1)/2 = 0, so it's correct.
Third one: x = (-3+-1)/2 = -2, y = (0+5)/2 ≠ 2, so it's not correct.
I really hope this helped.
