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:

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

Students get a 15% discount off the original prices at the Everything Fluorescent store during its back to school sale. Find the

spayn [35]

The discount is $1.19 unless you have to round up than it is $1.20. in order to solve this problem you would set up a proportion. So your proportion would be x over 7.99 = 15 over 100. Than you would cross multiply. 7.99*15=119.85. and 100*x=100x. than u divided both sides by a 100. than x= 1.19. which 1.19 is the discount.
