Subtract 2x from each side
2x+3=4x+1
-2x -2x
3=2x+1
subtract 1 from each side
3=2x+1
-1 -1
2=2x
divide each side by 2
2=2x
1=x
The domain is {-8}
The range is {5,6,7,8}
The relation is not a function as the domain value -8 maps to multiple values. All domain values in a relation needs to map to exactly one range value for it be a function.
Answer:
13-+4
Step-by-step explanation:
Answer:
X= 3.7
Step-by-step explanation:
Perimeter of rectangle= 2(L+B)
37= 2(4X+X)
37= 2(5X)
37= 10X
37/10=X
3.7= X
Answer:
The min is at x=4/3
Step-by-step explanation:
Take the first derivitave. Set that equation equal to zero. Then take the second derivative. Take the x values and put them into the second derivative. If the value is +, that means a rel min. If it is -, that means rel max.
