Answer:
x = {-0.44, 1.69}
Step-by-step explanation:
Multiply by the denominator to eliminate the fraction.
3 = x(4x -5)
4x^2 -5x -3 = 0 . . . . . subtract 3 and put in standard form
Using the quadratic formula with a=4, b=-5, c=-3, we have the solutions as ...

Solutions rounded to hundredths are ...
x = -0.44
x = 1.69
_____
A graphing calculator can show the x-intercepts easily, so it works well to write the equation in the form
f(x) = 0
3/(4x -5) -x = 0
Answer: d
Step-by-step explanation:
because in the text it states that you have to find the percentage of the budget allocated for food and round that budget to the nearest tenth and the budget is $800 so if we round 800 to the nearest tenth that would be $80.0%
Answer:
The average rate will be -11000 dollars per year.
Step-by-step explanation:
The price of a house in 2005 = $250,000
The price of a house in 2010 = $195,000
at x₁ = 2005, f(x₁) = 250,000
at x₂ = 2010, f(x₂) = 195,000
Using the formula to determine the average rate of change for the
house each year.
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [195,000 - 250,000
] / [2010-2005]
= -55000 / 5
= -11000
Therefore, the average rate will be -11000 dollars per year.
