HELP QUICKLY PLEASE Solve the system by graphing.

y = 3x + 5

y = 2x + 4

Drag the points to change the graph.

The solution is the point of intersection. What ordered pair represents the solution? Convince Me! How does the point of intersection of the graphs represent the solution of a system of linear equations?

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
