At the start of an adventure game, ralph had 100 coins. at the end of the game, he had 415 coins. ralph earned 45 coins for each successful mission. assuming he did not lose or spend any coins, solving which equation will show how many successful missions ralph completed? a. 7x - 100 = 315 b. 7x + 100 = 415 c. 45x - 100 = 315 d. 45x + 100 = 415

Your answer would be B, because you multiply (7)(45) and get 315, while you have too add the original 100 that he started with.

B: 7x + 100 = 415

answer: yes youre right.

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
