Answer:
(1/3)⁷
Step-by-step explanation:
negative exponents work like this: 
x⁻²=(1/x)²
Apply this theory to this equation:
3⁻⁷=

-- Look for all the 'a's      7a,  9a
-- Addum up                    16a
-- Look for all the 'c's      6c,  -15c
-- Addum up                     -9c
-- Write the results         16a - 9c

Answer:
-2, -13
0, -3
2, 7
4, 17
Step-by-step explanation:
To fill out the table, substitute the table x-values into the equation and the y-values will fill the table.
y = 5x - 3
y = 5(-2) - 3
y = -10 - 3
y = -13
This means the table value corresponding to -2 should be -13.
y = 5x - 3
y = 5(0) - 3
y = 0 - 3
y = -3
This means the table value corresponding to 0 should be -3.
y = 5x - 3
y = 5(2) - 3
y = 10 - 3
y = 7
This means the table value corresponding to 2 should be 7.
y = 5x - 3
y = 5(4) - 3
y = 20 - 3
y = 17
This means the table value corresponding to 4 should be 17.
