The correct answers are x≠2 and x≠(-2).
Domain restrictions are any points in the domain where the function will not have a value. This basically means that it's a point where x won't work in the function.
For the numerator, any value will work for x. We can have a value of 0 in the numerator, or a positive, negative, or decimal number.
However, the denominator cannot equal 0. This is because a fraction bar represents division, and we cannot divide by 0. The values that make the denominator 0 can be found by:
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.
Hey!
First, we need to know how many millimeters are in a centimeter.
<em>10 mm = 1 cm</em>
Okay, now we can write an equation.
<em>360 mm ÷ 10</em>
To solve this equation, we simply divide.
<em>360 mm ÷ 10 = 36 cm</em>
<em>So, if </em><span><em>Anoki bought 360 millimeters of fabric, that means he has </em> 36.0 centimeters <em>of fabric.</em>
Hope this helps!

Answer:
ano ang pinag kaiba noon kaysa ngayon
Answer:
The equation — E = mc2 — means "energy equals mass times the speed of light squared." It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing. If mass is somehow totally converted into energy, it also shows how much energy would reside inside that mass: quite a lot.
Step-by-step explanation:
Standard form allows you to easily find the y-intercept and determine if the parabola is concave up or down. Also, if it is not factorable, then it is in the correct form to apply the quadratic formula to find the x-intercepts.
