Answer:
-9
Step-by-step explanation:
You would transform 5x + 2x into the same term with the associative property, adding like terms. If you subsitute the different values into the expressions you notice that both have a rate of change of 7 like an arithmetic sequence. To see if any value will make the two expressions equal you make them equal to each other.
5x + 2x = 7x -1
7x = 7x - 1
0 = -1
No they will never have be a solution to both expressions to make them equal because they're parallel to each other.

Answer:
1/4
Step-by-step explanation:
slope=(y₂-y₁)/(x₂-x₁)
(9-8)/(6-2)
1/4
∴ Slope is 1/4
Answer:
± 8i
Step-by-step explanation:
note that 
= i
using the rule of radicals
• 
× 
⇔ 
, hence
= ± 
= ± 
× = ± 8i
