Answer:
Step-by-step explanation:
I know b is -9 because there's where the line crosses the y intersection.
To find ''m'', we can use 2 different methods. I'm going to use one that follows a formula. First, locate two points in the graph.
15% of 90 hours 15% of 90 hours

Okay, to do this, we need to do the Cross-Product Method. On one side, it will be x/90, and the other side will be 15/100. So, after we multiply 90 by 15, and also multiply 100 by x, out new equation is going to be 100x = 1350. After dividing 1350 by 100, we get 13.5
Answer: 15% of 90 hours is 13.5 hours.

Answer:
Please specify what the three expressions are.
Step-by-step explanation:
From what I understand, you need to set the expressions equal to each other. For instance, if one is 2(x-3) and the other is 2x-6, you could write it as:
Then, by evaluating it, you would get:
by distribution over subtraction.
by the additive property of equality
Simplify.
by the reflexive axiom.
Since x will always equal itself, 2(x-3) and 2x-6 are equivalent.
Therefore, if the expressions, once set equal to each other, result in the equation x=x, or any other expression in which one quantity equals itself, the two expressions are equal.
Sorry I could not be of more help, but you did not specify what the expressions were.
