V (-1,-9)
Y=1(x+1)^2-9
If you’re talking about the value of x in the quadratic equation then it is x=-4 &x=2
4 x+9=13 X=4 subtract 9 from the 9 and 13 and 13-9 =4 so x=4
Using proportions, it is found that the estimate of the the per capita consumption from 2011 was of 29.25 gallons.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The amount in 2012 was a increase of 5.3% from 2011, that is, 105.3% = 1.053 of x, and the consumption per capita was of 30.8 gallons, hence:
1.053x = 30.8
x = 30.8/1.053
x = 29.25 gallons.

Answer:
Unlikely, the probability is close to 0
Step-by-step explanation:
Given
Required
Determine the likelihood
The given probability, 0.15 is close to 0. This implies that the event is unlikely.
From the list of given options, option C answers the question
For part B
the fixed cost is 500 dollars because it is a set inital amount, the varibale cost is .15 because it is the cost dependent on something else (per indicated variable part)
y=.15x+500
.15 cents per flyer, add 500 because that is the set amount it costs to even create the flyer
Plug in 500 for the equation
y=.15(500)+500
y=75+500
y=575
for part a
b=ka for direct variations so the direct one is C - two items directly multiplied
y=mx+b for partial variation so its A,D - basically the equation of a line
A is neither - shows neither of these relationships
