Step-by-step explanation:
2. -x+4+3x+2=2x+6
3. -x-2-4x-3=-5x-5
4.-36-24=-60
5. 9+10-6-6=7
Answer:
X=5
Step-by-step explanation:
Multiply by 3 first
Because domain restrictions apply to this rational expression, x cannot be equal to {-2, 2}.
<h3>What is domain?</h3>
Domain restrictions are any points in the domain where the function will not have a value. This basically means that there is a point in the function where x will not work.
For the numerator, any value of x will suffice. We can have a value of 0 in the numerator, or a positive, negative, or decimal number.
However, the denominator cannot be equal to zero. This is due to the fact that a fraction bar represents division, and we cannot divide by zero.
Here,
x²-4=0
Add 4 to both sides:
x²-4+4 = 0+4
x² = 4
Take the square root of both sides:
√x² = √4
x = 2 or x = -2
The x cannot be equal to {-2, 2} as domain restrictions apply to this rational expression.

Axis of symmetry =-b/2a
so subsitiute
a=1,b=5
-5/2
i believe thr axis of symmetry is at -2.5
