The answers are that the number can equal -4 or 1.
You can find this by setting the number equal to x.
x^2 (The square of a number) + 3x (three times a number) = 4
x^2 + 3x = 4 ---> subtract 4 from each side
x^2 + 3x - 4 = 0
Then you can factor this to find the answers
(x - 4)(x + 1) = 0
Set both equal to 0 and solve.
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:
200 miles
Step-by-step explanation:
Set up a cost equation for each plan using x for miles.
Set the equations equal.
Solve for x, the miles.
For a 1 day rental.
Plan A:
C = 0.18x + 30
Plan B:
C = 66
0.18x + 30 = 66
0.18x = 36
x = 36/0.18
x = 200
Answer: 200 miles
It wouldn't be able to be because since all of the the numbers that could fit is probably going to be a decimal. Let's say we find 4 consecutive numbers of 32.
Equation:
x+(x+1)+(x+2)+(x+3)=32
4x+6=32
-6 -6
4x=26
x=6.5 1. 6.5, 7.5, 8.5, 9.5
As you can see, the consecutive number is going to be a decimal.
