Answer:
1
Step-by-step explanation:
=
so,
× = = 1
It is not true for expressions with negative exponents
X=7%
y=12%
x+y=20000
0.07x+0.12y=20000*0.19=3800
Answer:
there r 4 ppl wearing hats
Step-by-step explanation:
1/2 of 24 is 12
4+4+4=the other 12 take the other 2 4's away u got 4
Where f(x)=0 is the zeros of the funciton
factor out the common factor of all of them which is 9x
f(x)=9x(x^2+2x-15)
what 2 numbers multiply to get -15 and add to get 2?
5 adn -3
f(x)=(9x)(x+5)(x-3)
set to zero
9x=0
x=0
x+5=0
x=-5
x-3=0
x=3
zeroes at x=-5, 0,3
