A parabola, a graph of a quadratic function, cannot have a maximum vertex and a minimum vertex at the same time because of the shape of the graph. A parabola is a u-shaped graph. The vertex of the parabola is the point where the u changes direction; if it was increasing, it starts to decrease, and if it was decreasing, it starts to increase. Since a parabola only changes direction once, there will either be a minimum or a maximum, not both.
Answer:
24 pencils : 64 pens
Step-by-step explanation:
pencils : pens
12:32
Twice as many pencils mean multiply each by 2
12*2 : 32*2
24: 64
24 pencils : 64 pens
Answer:
A) 4 1/2
Step-by-step explanation:
8 - 4 1 / 2
4 1 / 2
= 4 1 / 2
Answer:
1. 2/4 = 1/2
2. 9/24= 3/8
3. 56/64= 7/8
Step-by-step explanation:
So 9x^2+12x+4=0
so the quadratic formulat is (-b+/-(squrt(b^2-4ac)))/(2a)=x
subsitute
ax^2+bx+c=
9=a
12=b
4=c
(-12+/-(squrt(12^2-4(9)(4))))/(2(9))=x
(-12+/-(squrt(144^2-144)))/18)=x
(-12+/-0)/18)=x
-12/18=x
-2/3=x
