What is the quotient of (125-8x^3)/(25+10x+4x^2) a)-2x+5 b)2x-5 c)-2x-5 d)2x+5

A

Step-by-step explanation:

For the expression , simplify  the expression by factoring the numerator and denominator if possible.

After factoring the difference cubes, you can divide by itself into 1 leaving 5-2x. This can also be written as -2x+5.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
