Eduardwww [97]

Answer:

7 Hours

Step-by-step explanation:

Given The lawyer charges $100 per month for a client.

Also he charges $75 per hour

Let the hours he worked for the client be x

The money the lawyer gets from the hourly charges is $75x

The total money the lawyer charged is $625

4.8a - 6.3b - 2.1a + 7b
ololo11 [35]
First, you combine like terms. I would start by circling the term and the sign in front of it. (A term is a piece separated by an addition/subtraction sign.) You can only combine terms with the same variable. 4.8a-2.1a-6.3b+7b is the same as your equation, just rearranged. Then, subtract (4.8a-2.1a) which is 2.7a. Add (-6.3b to 7b) The answer is 0.7b. If you have any questions, you can message me!

23. What is the equation of the line that contains the points (2, 1) and (-1, -8)?
Sauron [17]
I'm guessing this is a slope problem, so the equation would be like this: y = mx + b where m is the slope and b is the y-intercept.

m =  \frac{y1 - y2}{x1 - x2}
Using this,
m =  \frac{1  + 8}{2  + 1}  =  \frac{9}{3}
Which is equal to,
m = 3
