If the degree is even, then both ends of the graph go in the same direction, either both up or both down
if the degree is odd then both ends go in oposite directions
if the leading coefient (coefient of the highest powerd placeholder) is negative, then 2 possiblities could happen
1. if the degree of te function is even, then both ends point up
2. if the degree is odd, then the ends go from top left to bottom right
so we've got f(x)=-4x^6+6x^2-52
even degree and negative
so both ends point down
goes from bottom left to bottom right
B and D are the answers
Let her monthly salary be x
1/8x = $65
x = $65 × 8 = $520
Her weekly pay is $520 ÷ 4 = $130

Step-by-step explanation:
Okay, well for a right triangle with legs a and b and hypotenuse c we have:
a2+b2= c2
since we know the hypotenuse (c), we have:
a2+b2= 25
since the short leg is 1 inch shorter than the longer leg,
we can say that a = b-1
So now we have:
(b-1)2+ b2 = 25
b2 - 2b +1 +b2 = 25
2b2-2b -24 = 0
2(b2-b-12) = 0
b2-b-12 = 0
(b-4)(b+3) = 0
Because you can't have a negative length, b = 4
If b = 4, then a = 4-1 = 3
So,
b=4
a=3
as you can see you have to use commutative property given !!!!!!!!!
