Answer: The only graph that shows a proportional relationship is the line that crosses the origin point (0,0).
Explanation
The other graphs are linear functions but not not proportional relationships.
The general form of a proportional relationship is y = kx, where k is the proportionality constant. So, for x = 0 you will always obtain y = 0.
The general form of a linear relationshio is y = kx + b, being b the y-intercept, so if the y-intercept is not 0, it is not a proportional relationship. That is what happens with the other three graphs.

Step-by-step explanation:
Answer:
Step-by-step explanation:
3x^2 + 5x + 25 when x = 3
= 3(3)^2 + 5(3) + 25
= 3(9) + 15 + 25
= 27 +15 + 25
= 67
Please state the full question what percent of what DVD in her collection we dont have enough information to give you an answer, I will just list all the possible answers,
8+12+7+3 =30
Possible answers
Action = 8/30 = 26% or 27% depending if you are rounding
Comedy = 12/30 = 40%
Romance = 7/30 = 23%
Science Fiction = 3/30 = 10%
Answer:
93/100
Step-by-step explanation:
In a group of 100 students, 60 are freshman, 55 are female, and 22 are female freshman. Find the probability that a student picked from this group at random is either a freshman or female
Number of Freshman = 60
Number of female = 55
Number of Freshman female 22
Total number of students = 100
The probability that a student picked from this group at random is either a freshman or female
Thus P(freshman or female) = 60/100 + 55/100 - 22/100 = 93/100
