Answer:
Distance between Gas Station and House = 7.81 miles.
Step-by-step explanation:
Given: House location ( 4, 3 ) and Gas station location ( 10, 8)
On graph 1 unit = 1 mile.
To find: Distance between Gas Station and House
We use the Distance formula to find the distance between two points 

From given points and formula,

= 
= 
=
units
Since, 1 unit = 1 mile
⇒ 
Therefore, Distance between Gas Station and House = 7.81 miles.
Given:
Year 0 = 2005 = 90,000
Year 1 = 2006 = 91,200
(91,200 - 90,000)/90,000 = 1,200/90,000 = 0.013
f(x) = 90(1.013)x
f(1) = 90(1.013)1
f(1) = 91.170
The second option, f(x) = 90(1.013)x, is the best representation of the relationship between x and f(x).
Answer:
(7,-3)
Step-by-step explanation:
y = -3
substitute in the first equation
3x - y^2 = 12
3x - (-3)^2 = 12
3x - 9 = 12
3x = 12 + 9
3x = 21
x = 7
coordinates of intersection (7,-3)

notice the original, and the new one, with the tripled "r" and "h" is just, whatever the original was times 27, namely 27 times as large as the original.
The inequality that represents this phrase is n+6 > 31.
