Below are two expressions, the only difference being the presence or absence of parentheses. expression 1: expression 2: 4 2×(3 4)×(5−2)4 2×3 4×5−2 calculate the difference between the two expressions; that is, evaluate both expressions then subtract one value from the other value.

What we are going to do is develop both expressions separately.
 Expression 1:
 42 * (34) * (5-2)
 1428 * (5-2)
 4284
 Expression 2:
 42 * 34 * 5-2
 7140-2
 7138
 The difference between both expressions is:
 7138-4284 = 2854
 
 the difference between the two expressions is 
 2854

Y= 4/5 x + 24
To find the rate of change you find the difference in each of the numbers on the graph. For example, 36-32 is 4. So 28-4 is 24 and that would be the next number down. It would also match x to be 0 because since the rate of change for x was 5, if you subtract 5 from 5 you get 0. So from this we know that the coordinates would be 0,5.
From this info, the slope would be 4/5 and the y intercept or initial value would be 24
