Answer:
x=4, y=1
Step-by-step explanation:
3.6x + 1.6y = 16
1.2x+3.2y = 8
Multiply the first equation by -2
-2(3.6x + 1.6y) = 16*-2
-7.2x -3.2y = -32
Add this to the second equation to eliminate y
-7.2x -3.2y = -32
1.2x+3.2y = 8
--------------------------
-6x = --24
Divide each side by -6
-6x/-6 = -24/-6
x=4
Now to find y
Multiply thesecond equation by -3
-3(1.2x+3.2y) = 8*-3
-3.6x -9.6y = -24
Add this to the first equation
-3.6x -9.6y = -24
3.6x + 1.6y = 16
---------------------------
-8y = -8
Divide each side by -8
y = 1

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:
I tried to answer but I still would like to know what doesn't make sense.
Considering the identity:
The identity is true whenever both sides are defined. It is not supposed to hold the values when we have division by zero, because it is undefined.
If the value doesn't make sense, it is probably not a function, or it is undefined by the given value of .
Let's go back to the definition of function again:
A function relates a set of inputs and a set of allowable outputs where each input is related to only one output. It basically defines the relation of ordered pairs.
