Answer:
a = -1
Step-by-step explanation:
first you make the x 0 and the y 0
0 = (0 - 1)^2 + a
0 = (-1)^2 + a
then you deal with the exponent
0 = 1 + a
lastly you subtract everything by 1
-1 = a
a = -1
that is your answer
Answer:
Every year, the deductions total up to $384 a year, because 12 x 32 = 384. :)
We know that:
limx→0
sin(x)/x
= 1.
and
cscx = 1/sinx
so,
<span>limx→0 x/sinx = 1</span>
2y^2-7y+6= 2y^2-4y-3y+6
=2y(y-2)-3(y-2)
=(2y-3)(y-2)
Therefore
y=3/2 or y=2
