To find the answer, we multiply 1,047.30 by 6.2% which is 0.062 in percentage.
1047.30 x 0.062 = 64.93
64.93 is being taken away.
Answer:
x+1 , x<-1
x²-bx-4 , -1≤x≤4
1/2 x +a
substitute x=-1 , continuous everywhere
x+1=x²-bx-4 when x=-1
-1+1=-1²-b-4
<h2>1+b-4=0 ⇒ +b-3 ⇒ b=3</h2>
then for :
x²-bx-4=1/2 x +a for x=4
4²-4b-4=1/2x+a
16-4(3)-4=4/2+a
16-12-4-2=a
<h2>a=-2</h2>
the equations will be :
x+1
x²-3x-4
1/2x-2

Answer:
A: 5
B: 6
C: 3x^2 - 2x
D: 8
E: 22
Step-by-step explanation:
A: (-1)^2 + 4 = 5
B: (-4)^2 +4 = 16
2 x (-3) -4 = -10,
16-10=6
C: 3(x^2 + 4) = 3x^2 + 12
3x^2 + 12 -2x -4, simplify
3x^2 - 2x
D: g(3) = 2*3 -4 = 2
f(2) = 2^2 +4 = 8
E: f(3) = 3^2 + 4 = 13
g(13) = 2*13 - 4 = 22
