Answer: think of your problem as Ax +By=C. You get your x intercept and y intercept by c divided by A and c divided by B. Put the y intercept on the y axis and x intercept on the x axis
C The game is not fair and they should stop playing
Try this solution:
1. note, the equation of the given line is y= - (3/2)x - 1;
2. the area, represented by the graph is on the left side of the line. It means, the inequality included '<' sign.
3. totaly: y< -3/2 x - 1
Answer: x is 20
Step-by-step explanation:
This is ratio
a : c = b : x and d : unknown
a : c = 9 : 12 = 3 : 4 which is 9/12
b : x = 15 : x which is 15 / x
So the proportion will be :
3/4 = 15/x
So Cross multiplying
3x = 90
Divide both side by 3
x = 90/3
x = 20
