Kishi draws a parabola with vertex at (6, 8) and x-intercepts at (2, 0) and (10, 0). Which is the equation of the parabola in standard form? y=−(12)x2+6x−10

y=−(12)x2−6x−10

y=(12)x+6x−10

y=−(12)x−6x+10

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
