To be able to quickly solve this, we can temporarily make 5.47 into 547
Now, we can divide 547 by 12.

Now, we can round up from 45.5 to get 46.
However, we originally moved our decimal 2 places over, so now we must move it 2 places again.
46 ⇒ 0.46
The correct answer is $0.46
-x^2 - 2x - 5=0
-(x^2 + 2x + 1) -4=0
(x +1)^2= -4
=> Impossible. There is no x
Evaluate f(1) and g(1)
f(1)=2(1)^2-1+5=2(1)+4=2+4=6
g(1)=3(1)^2-3(1)-2=3(1)-3-2=3-5=-2
f(1)+g(1)=6-2=4
h(1)=4
ANSWER



EXPLANATION
Since line l is parallel to line m,

because the two angles are vertically opposite angles.

because the two angles are corresponding angles.

because the two angles are alternate exterior angles.
Answer:
Step-by-step explanation:
-12-(-8)+(-3)= -12+8-3
=-12+-3+8
= -15+8
= -7
