Find the x-intercepts of the parabola with vertex (1, -9) and y intercept at (0, -6).
weqwewe [10]
  • Vertex Form: y = a(x - h)^2 + k, with (h,k) as the vertex.

So firstly, plug the vertex into the vertex form: y=a(x-1)^2-9

Next, we first need to solve for a. Plug (0,-6) into the equation to solve for a as such:

-6=a(0-1)^2-9\\-6=a(-1)^2-9\\-6=a-9\\3=a

<u>Now we know that our equation is y = 3(x - 1)^2 - 9.</u>

Now to solve for the zeros (x-intercepts). Set y to 0 and add 9 to both sides of the equation: 9=3(x-1)^2

Next, divide both sides by 3: 3=(x-1)^2

Next, square root both sides: \pm\sqrt{3}=x-1

Next, add 1 to both sides: 1\pm\sqrt{3}=x\\2.73,-0.73=x

<u>Your x-intercepts are (-0.73,0) and (2.73,0), or B.</u>

Which fraction is equal to 5/6? 8/22, 25/30, 5/15?
nadya68 [22]
If the fraction cannot be simplified any more, you can multiply both the numerator and denominator by an number.

5/6 (multiply the top and bottom by 2) is the same as 10/12
8/22 (can be simplified by dividing top and bottom by 2) is 4/11
25/30 (simplified by dividing by 5) is 5/6
5/15 (simplified by dividing by 5) is 1/3

Hope this helps!
