Answer: Vertical Stretch
Step-by-step explanation:
Given: The cost of manufacturing x refrigerators is given by the function :
If the cost doubles fr the year 2011 owing to higher raw material prices, then we multiply the given function by 2, then we get a new function :
which represents a vertical stretch in the graph.
∵ 2 is a positive constant greater than 1 which is multiplied to the parent function f(x). So by the definition of vertical stretch the parent function will be vertically stretched .
Answer:
x=3
Step-by-step explanation:
1. Simplify the expression
7x-\left(3\cdot\left(x-6\right)\right)=30
Solve by distributing:
7x-\left(3x+3\cdot-6\right)=30
Simplify the arithmetic:
7x-\left(3x-18\right)=30
Expand the parentheses:
7x-3x+18=30
Simplify the arithmetic:
4x+18=30
