The correct answer is false. The symmetry of a hyperbola with a center at (h, k) do not occurs only at y = k and x = h. The axis of symmetry occurs through each focus making right angles to the directrix. The axis of symmetry is a line that divides a graph or something into two congruent figures.
The trick is to realize what your choices are.
if m or n or both are divisible by 5, then 2mn will be divisible by 5
I don't know if you know about x mod(5), but in that case there can only be 4 possibilities for m and n
m mod (5) = +/- 2 or m mod(5) = +/- 1
In the first case m^2 = 4 mod(5) and in the second case m^2 = 1 mod(5) N has the same considerations.
If m and n have the same modular results (both are [say] 2 ) then m^2 - n^2 which be 0
If they are different, then (m^2 + n^2) mod 5 = 0
To solve this we must set up a proportion.
For each pie we need 2 pounds because you divide 4 by 2.
So we do 5 times 2 which gives us 10 pounds per 5 pies
Your answer is
You need 10 pounds of apples for 5 pies.
The rate of change is 10.5/3
It cost $3.50 per yard
The total cost for 8 yards is $28
If the total cost of buying fabric is $42 the amount of yards that were bought would be 12
