8 : 4
16 : 8
4 : 2
Simplest:
2 : 1
the discriminant b^2 - 4ac when the equation is in the form of ax^2 +bx+c=0
13x^2-16x = x^2 -x
we need to get in it the standard form
subtract x^2 from each side
12x^2 -16x = -x
add x to each side
12x^2 -15x = 0
12x^2 -15x -0 =0
a=12 b=-15 c=0
b^2 -4ac
the discriminant = b^2
b^2 = (-15)2 = 225
Answer:
1st box: (-5,-2)
2nd box: up and down
3rd box: 8
4th box: +-4/3
5th box: y+2 = +-4/3 (x+ 5)
Step-by-step explanation:
Just took the k12 unit test, hope this helps!
7/6π" (or 1.17π"). To find the circumference (therefore the distance the hand travels) you do 2rπ (radius is 7in), which is 14π, then divide it by 12 bc the hand is only moving five minutes (which is simplified to 7/6π). You can't simplify π.
can you show me a picture then maybe i can help you
