How many points does the given equation have in common with the x-axis and where is the vertex in relation to the x-axis. y=x^2-
Fudgin [204]

Answer:

1. It has two points in common with the x-axis.

2. The vertex in relation to the x-axis is at x=6

Step-by-step explanation:

The points that the equation has in common with the x-axis are the points of intersection of the parabola with the x-axis.

To find them, substitute y=0 and solve for "x":

y=x^2-12x+12\\0=x^2-12x+12

Use the Quadratic formula:

x=\frac{-b\±\sqrt{b^2-4ac}}{2a}\\\\x=\frac{-(-12)\±\sqrt{(-12)^2-4(1)(12)}}{2(1)}\\\\x_1=10.89\\\\x_2=1.10

It has two points in common with the x-axis.

To find the vertex in relation to the x-axis, use the formula:

x=\frac{-b}{2a}

Substituting values, you get:

x=\frac{-(-12)}{2(1)}\\x=6

What is a simpler form of the following expressions?
nadezda [96]

Answer:

D. 49p² - 64

Step-by-step explanation:

(7p - 8)(7p + 8)

Solving this requires the 'difference of squares' concept which states;

If (a - b)(a + b)

Then the solution must be a² - b²

Considering (7p - 8)(7p + 8) then the answer is;

(7p)² - 8² = 49p² - 64
