Insert the slope and point into point-slope form:-
y - 1 = 3/4(x - 2)
y = 3/4x - 6/4 + 1
y = 3/4x - 1/2
The solution is r= 7/a-x How did i do this?
Your equation is ax+ r=7, so the goal is to isolate the r. You begin by dividing the a from the ax. Remember, what you do to one side, you must do to the other. So you do 7/a, since you can't simplify 7/a, leave it as it is. Next, your equation should look like this x+r=7/a. In order to isolate the r, you move the x to the other side by subtracting, which leaves you with the answer of r= 7/a-x.
Hope this helped!
Answer:
Total number of pages is 540.
Step-by-step explanation:
Let mark read x be he number of pages per day and d be the number of days to finish the book.
Total number of pages = xd
Mark reads 18 pages less per day than originally planned, he will need 5 extra days to finish the book.

.... (1)
He reads 24 pages less per day, he will need 8 extra days to finish.
... (2)
Subtract 5 times of equation (2) from equation (1).
Substitute d=10 in equation (1).
Divide both sides by 5.
Total number of pages
Therefore , the total number of pages is 540.
No 8.
Use proportion time to return home = (52 * 6) / 60 = 52/10 = 5.2 hours
That is 5 hours 12 minutes
The first answer is C.
The second answer is A.
