How many solutions are in 10(x + 4) – 3 = 14x + 1

one solution

Step-by-step explanation:

since the variables are only to a power of one, the options are no solutions, one solution, and infinitely many solutions.

using the distributive property, 10(x+4)= 10x + 40. simplify the equation 10x + 40 - 3 = 14x +1 to 10x + 37 = 14x + 1. move variables to one side and constants to another to get 4x = 36. divide to get x=6. so the answer is one solution

since we don't have something like 1=0 where two unequal constants are said to be equal, the answer isn't no solutions

since we dont have something like 1=1 where the two sides of the equation are equal no matter what x is, the answer isn't infinitely many solutions

only one

x = 9

Step-by-step explanation:

how many solutions are in 10(x + 4) – 3 = 14x + 1

10(x + 4) – 3 = 14x + 1

10x + 40 - 3 = 14x + 1

-4x = 36

x = 9

only one

x = 9

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
