Simplify both sides of the equation(-1.3x+-7.4x)+(7)=(1.5x+-6x)+(9)
-10.5x+7=-4.5x+9
Add 4.5 to both sides
-6x+7=9
Subtract 7 from both sides
-6x=2
Divide both sides by -6
x= -1/3
-450 + 12x.....this is basically stating that the sewing machine and some fabric cost him $ 450....and he is selling each blanket for $ 12 a piece.
The total amount he earns is 12x....where x is the number of blankets
The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.
