Answer:
Step-by-step explanation:
we are given a quadratic equation
Let's assume formula of vertex form of parabola as
where vertex is (h,k)
we are given
vertex =(11,-2)
so, h=11, k=-2
now, we can plug it
now, we are given zeros at x=10 and x=12
we know that zeros will be x=10 , y is 0
so, we can plug x=10 and y=0 and solve for 'a'
now, we can plug it back
and we get
so, we get quadratic equation as
Answer: She will use 6 cans of pinto beans .
She will use 6 cans of kidney beans.
Step-by-step explanation:
As per given,
For bean salad : lima beans : pinto beans : kidney beans
= 3:2:2
Let quantity of lima beans = 3x, pinto beans 2x , kidney beans 2x.
if she use 9 cans of lima beans, then
3x=9
⇒x=9
Now, 2x= 2 x 3 =6
Thus , she will use 6 cans of pinto beans and 6 cans of kidney beans.
Answer:
12/7 is a improper fraction
Step-by-step explanation:
as a decimal it is 1.71428571429 and as a mixed number it is 1 5/7
Answer:
This can't really be factored, but it can be expanded slightly.
(3x³)³ = 27x⁹
Since PQ bisects CX at point J, JX=CJ
4y=y+9
-y -y
3y=9
divide by 3
y=3
