His allows you to set up a summation of the form:
Summation from i = 1 to 500 of i.
The general solution to the summation of i from 1 to n is n(n+1)/2. In this case, n = 500.
500(501)/2 = 125250
Recall that you divided the sum by 2 to simplify its computation. Now multiply your result by 2 for your final answer:
125250 * 2 = 250500
Combine all the likes terms first, your answer would be a + 6b
Answer:
The graph cannot represent a proportional relationship
Step-by-step explanation:
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form. In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin (0,0) . That means, ----> The x-intercept and the y-intercept of the line must to be the origin (0,0).
If the given line passes through the point (0,5), then the line does not pass through the origin. Therefore, the graph cannot represent a proportional relationship
