Step-by-step explanation:
Let's take cost of 1 hamburger as h and the cost of 1 hot dog as d.
Therefore, we can form the equations:
3h + 2d = 13 and
2h + 4d = 14
2(h +2d) = 14
h + 2d = 7
h = 7 - 2d
By substituting this to the first equation, we get:
3(7 - 2d) + 2d = 13
21 - 4d = 13
4d = 8
d = $2
h = 7 - 2(2)
h = $3
Hence <u>1 hot dog costs $2</u> and <u>1 hamburger costs $3</u>

Points: (3, -5) and (-7, -1)
Slope Formula:
Answer:
Answer is c
Step-by-step explanation:
Given an expression in n as
We are asked to find out the limit as n tends to infinity
The given term has degree 1 for n in the numerator and degree 2 for n in the denominator
When n tends to infinity, since n is very large, we can say n^2>n
IN other words denominator having square of n approaches infinity faster than the numerator
This gives the limit as a finite value/infinite =0
HEnce limit =0
x+(-2) >3
open the bracket
x-2>3
collect the like terms by taking 2 to the other side
x>3+2
x>6
