.
for it is a denominator. Multiply both sides with the product of the two denominators: 
:
.
.
Multiply both sides by one over the coefficient of x:

Answer:
The formula for this quadratic function is x*2 +6x+13
Step-by-step explanation:
If we have the vertex and one point of a parabola it is possible to find the quadratic function by the use of this
y= a (x-h)*2 + K
Quadratic function looks like this
y= ax*2 + bx + c
So let's find the a
y= a (x-h)*2 + K where
y is 13, x is 0, h is -3 and K is 4
13= a (0-(-3))*2 +4
13=9a +4
9=9a
9/9=a
1=a
The quadratic function will be
y= 1(x+3)*2 + 4
Let's get the classic form
(x+3)*2 = (x+3)(x+3)
(x*2+3x+3x+9)
x*2 +6x+13
f(0) = 13
2.54-1.66
0.88
the answer is 0.88
Answer:
There is not enough information to answer this question. Is there perhaps a diagram or table provided?
Step-by-step explanation:
One class is 45 minutes.
That's 90 minutes per week.
8 weeks times 90 minutes is 720 minutes.
720 minutes divided by 60 minutes in the hour is 12 hours. Answer C.
