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:
<h2>y = 5x - 7</h2>
Step-by-step explanation:
The slope-intercept form:

m - slope
b - y-intercept
We have the slope m = 5. Therefore we have the equation

Put the coordinates of a given point (2, 3) to the equation:
x = 2, y = 3

<em>subtract 10 from both sides</em>

Finally:

The statement "the diagonals are perpendicular ti each other" is sometimes true and sometimes false
