Answer:(9y-7)(9y+7)
Step-by-step explanation:
81y^2-49
=(9y)^2-(7)^2
=(9y-7)(9y+7)
Answer:

Step-by-step explanation:
Since the equation is parallel, this means that the slope remains the same which is 0.5.
The remaining thing to do is to find b or y-intercept. To do that, the point (6,-2) and the slope of 0.5 will be used.

When solving for b, it will equal to -5.
Therefore the new equation that is parallel is 
we know that
if the lines a and b are parallel lines cut by transversal f
then
--------> by alternate exterior angles
solve for x

therefore
<u>the answer is</u>
the value of x is 
Answer: 10.00%
Step-by-step explanation:
With no other data, assuming equal attendance it's 1/5 that it's a visitor to Museum 3, and 1/2 that it's a man. So 1/5 × 1/2 = 1/10
