We want to solve 9a² = 16a for a.
Because the a is on both sides, a good strategy is to get all the a terms on one side and set it equal to zero. Then we apply the Zero Product Property (if the product is zero then so are its pieces and Factoring.
9a² = 16a
9a² - 16a = 0 <-----subtract 16a from both sides
a (9a - 16) = 0 <-----factor the common a on the left side
a = 0 OR 9a - 16 =0 <----apply Zero Product Property
Since a = 0 is already solved we work on the other equation.
9a - 16 = 0
9a = 16 <----------- add 16 to both sides
a = 16/9 <----------- divide both sides by 9
Thus a = 0 or a = 16/9
Answer:
FEJ and JED
Step-by-step explanation:
Supplementary means that the pair of angles add up to 180° or a straight angle. FEJ and JED are both 90° and so they add up to 180° But there are many pairs of angles that are NOT 90° that add up to 180° (but they just weren't in the answer choices)

Step-by-step explanation:
you have to be careful with the precise notation of terms and expressions.
you keep using only -7 for everything.
i suspect you mean 7 and -7, right ?
if that is correct, then just remember this :
on a number line the positive values are on the right, and the negative values on the left.
in fact, the further right you go, the larger the number gets. and the further left you go, the smaller (or lower) the number gets.
e.g. -7 is smaller than -6.
and so, -7 would be to the left of 7, because -7 < 7.
or vice versa :
7 would be to the right of -7, because 7 > -7
