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

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
