Answer:
-14+63x²
Step-by-step explanation:
(sot)=s(tx)
=s(3x)
=2-(3x)²
=2-9x²
(sot)(-7)=-7(2-9x²)
=-14+63x²
I hope I helped

<span>The distance
between two points (x₁,y₁),(x₂,y₂) = d

The coordinates of point F = (-2,4)
The coordinates of point E = (-7,0)
the length of line segment FE = <span>

5 ones is the same as 5 times 1 which is 5
50 tens is the same as 50 times 10 which is 500
So 50 tens is larger than five ones. Hope that helped. Have a nice day
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.
