Answer:
m = -3
Step-by-step explanation:
Slope Formula: 
Simply plug in our coordinates to find slope:
m = (11 - 2)/(5 - 8)
m = 9/-3
m = -3
Answer:
Well.. its already in standard form..
but even if u want u can write it as 8 X 10^(-1)
Step-by-step explanation:
Standard form is used for quite big decimal numbers
like : 0.2356
We can write it as 2.4 X 10^(-1)
Simply add up all.
4 1/2 + 6 2/3 + 9 1/4
(4 + 6 + 9) + 1/2 + 2/3 + 1/4
19 6/12 + 8/12 + 3/12 = (6+8+3)/12 = 17/12
19 17/12
19 1 5/12
19 + 1 5/12
= 20 5/12
20 5/12 yards was purchased.
1) 2x + 9 = 2x -5
9 ≠ -5 ; No solution
2) 2x- 1 = x + 3
x = 4; One solution x = 4
3) x + 2 = x + 2
0 = 0; Identity (or all real numbers)
