don't under stand your question please
Step-by-step explanation:
By Law of Indices,
8^(-2) = 8^0 / 8^2
= 1 / 64.
A.
(7^2)^x = 1
(49)^x = 1
thus x = 0
B.
<span>(7^0)^x=1
(1)^x = 1
thus x can be any real number.

Answer:

Step-by-step explanation:
Given:
19x + 9y = 15
Required:
Rewrite in slope-intercept form, y = mx + b
SOLUTION:
19x + 9y = 15
Subtract 19x from both sides
9y = -19x + 15
Divide both sides by 9
y = -19x/9 + 15/9
