The graph of the relation between x and y is as shown in attached figure
By applying the vertical line test we find that the relation is not a function because there are two points which are (1,-1) , (1,3) have the same value of x with different values of y which contradicts with with the rule of function.
If $0.35=1 ounce
?=8.5 ounces
8.5/1*$0.35=$2.975 Therefore 8.5 ounces cost $2.975
If 1 ounce =$0.35
12.2 ounces=?
12.2/1*$0.35=$4.27
Therefore 12.2 ounces cost $4.27
Z = x-y(3r)/y
z = x-y * 3r/y
Final answer: x = yz + 3yr
Answer:
x= -6
Step-by-step explanation:
3x+4= 2 (x - 1)
3x+4= 2x -2
Subtract 4 from both sides of the equation
Simplify
Subtract 2x from both sides of the equation
Simplify
= -6
