Whats the inequality for the graph?

Step-by-step explanation:

An inequality or equation for a graph is written in Y=MX +B form.

y and x are untouched while you need to do math to find M and B

M is the slope:

Slope is

how much you rise from one point to the next and how much you run from one point to the next. this graph gives us 2 points. (0,0) and (4,3)

to go from the first coordinate to the next you need to go up by 3 and over by 4 so 3over4.

This gives us

We still have to find B.

B is the y intercept. What Y position does the graph cross the Y Axis.

in this case it is at 0

so we put a zero for b.

last step: In our inequality we don't know if y is greater than or less than our equation.

The shading is under the line so Y is less than.

If it's over Than Y is more than...

Also we know that Y is less than some thing but not equal to it because the inequality is drawn as a dotted line not a solid straight one.

in this case Y is less than 3/4X + 0

Aka

add 5 subtract 1

step-by-step explanation:

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.
