Answer:
a) 4 ; b) 8
Step-by-step explanation:
4×3-8 = 12-8 = 4
4×4-8 = 16-8 = 8
Answer:
1, 2, 3, 6, 9, 18.
Step-by-step explanation:
factor pairs: (1 and 18), (2 and 9), (3 and 6)
(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!

Step-by-step explanation:
Answer:
y = -2x + 1
Step-by-step explanation:
y = mx + c
m = -2
y = -2x + c
x = -1, y = 3
3 = -2(-1) + c
3 = 2 + c
3 - 2 = c
c = 1
y = -2x + 1
