B. -9 is the most negative one, -2 is the least.
Hope this helps you.
6(7 - 2)
6(5)
Check:
7*6 = 42
2*6 = 12
42-12 = 30 = 6(5) :)
(7t-2) - (-3t+1) = -3*(1-3t)
First distribute:
7t-2+3t-1 = -3+9t
Now get all the terms with 't' on the same side by subtracting/adding:
7t+3t-9t = -3+2+1
Combine the terms:
1t=0
t=0
Check:
Plug in 0 for t and see if both sides of the equation come out the same:
Does (7(0)-2) - (-3(0)+1) = -3(1-3(0)) ?
(-2) - (1) = -3(1) ?
-3 = -3 ?
Yes! It works, so t=0!
The coordinates of the fourth vertex are (0,0). I hope this helps!
