First you have to do 440 / 20, which is 22 cents per bottle
Next you have to do 480 / 24, which is 20 cents per bottle
20 < 22, so the 24 ounces of shampoo is the correct answer.
Answer:
x = -7/2 and x = 1
So, there are 2 roots of this equation.
And the roots are real numbers.
Step-by-step explanation:
We need to describe the nature of roots for this equation
2x^2+5x-7=0
2x^2-2x+7x-7=0
2x(x-1)+7(x-1)=0
(2x+7)(x-1)=0
2x+7=0, x-1=0
2x=-7, x =1
x = -7/2 and x = 1
So, there are 2 roots of this equation.
And the roots are real numbers.
Domain (-infinity,infinity)
Range (-infinity, infinity)
Just multiply 9x9 then mutiply the answer by 9 and there you go
