Step-by-step explanation:
because you do the Pythagorean theorem and you get 7.81024976 and that is a irrational number
Answer: x=12
Step-by-step explanation:
5x-15=2x+21(AIA)
3x-15=21
3x=36
x=12
Answer:
(−7)(−6)(−5) so the zeros are 5, 6, &7
Step-by-step explanation:
Answer:

Step-by-step explanation:
The hyperbola has x-intercepts, so it has a horizontal transverse axis.
The standard form of the equation of a hyperbola with a horizontal transverse axis is 
The center is at (h,k).
The distance between the vertices is 2a.
The equations of the asymptotes are
1. Calculate h and k. The hyperbola is symmetric about the origin, so
h = 0 and k = 0
2. For 'a': 2a = x₂ - x₁ = 3 - (-3) = 3 + 3 = 6
a = 6/2 = 3
3. For 'b': The equation for the asymptote with the positive slope is

Thus, asymptote has the slope of

4. The equation of the hyperbola is

The attachment below represents your hyperbola with x-intercepts at ±3 and asymptotes with slope ±2.
