Answer:
The translation of the question is: " Angelfish are 4/7 and gladiolus 5/9 of all fish in a certain aquarium. Are there more angelfish or gladiolus in this aquarium?
The answer is: there are more angelfish.
Explanation:
You have the fraction for both angelfish and gladioulus in a certain aquarium, so you need to compare those fractions to conclude which fraction is greater.
To compare fractions you can divide one by the other. Whether the quotient (the result of the division) is greater than, equal than, or less than one will tell which fraction is greater than the other.
- If fraction 1 / fraction 2 > 1 ⇒ fraction 1 is greater than fration 2
- If fraction 1 / fraction 2 = 1 ⇒ fraction 1 is equal to fraction 2
- If fraction 1 / fraction 2 < 1 ⇒ fraction 1 is less than fraction 2.
Now, lets compare the fish's fractions:

Then, you conclude that 4/7 is greater than 5/9, and thus the fraction of angelfish is greater than the fraction of gladioulus: there are more angelfish in the aquarium.
4(x-1)=-4+4x
4x-4=-4+4x
-4x -4x
-4=-4
Not sure what the problem was asking, but it’s solvable!
Since sine and cosecant are reciprocals, when one has a maximum the other has a minimum and vice versa.
That's choices B & D
Not sure what the question at the end is asking; at 90 degrees and also at -90 degrees the values of sine and cosecant are equal.
Ok so domain is all allowed numbers
look at deonomenator and don't allow any numbers that will make it zero
none
that means
domain=all real numbers
vertex
in form
y=a(x-h)^2+k
(h,k)=vertex
we have
y=-2(x+3)^2-1
h=-3
k=-1
vertex=(-3,-1)
range
the vertex opens down so max is y=-1
y≤-1
domain is all real
vertex is (-3,-1)
y≤-1
