Answer:
The absolute value vertex is (5, 10). Please check that graph is also attached for the absolute equation with vertex (5, 10).
Step-by-step explanation:
Considering the absolute value equation

To find the x coordinate of the vertex, set the inside of the absolute value
equal to zero.
In this case,

Replace the variable x with 5 back into the equation and solve for y.



Therefore, the absolute value vertex is (5, 10). Please check that graph is also attached for the absolute equation with vertex (5, 10).

Answer:
Step-by-step explanation:
Given the expression 4^{-2}•7^{-2}. The following expression are equivalent to given expression on simplification.
Generally from indices, a^-b = 1/a^b. Applying this to the given expression we have:
4^{-2}•7^{-2} = 1/4^2 • 1/7^2
= 1/(4×4) • 1/(7×7)
= 1/16 • 1/49
= 1/(16×49)
= 1/784
