Multiply the equations to get the coefficients Greatest Common Factor:
3(2x+4y=11)
2(3x+6y=17)
6x+12y=33
6x+12y=34
Then you subtract them:
0x+0y=-1 0=-1
Or in other words no solutions
Answer:
Option C
Step-by-step explanation:
A function is said to be one-to-one if every y value has exactly one matching x value that is mapped onto it.
A function is said to be many-to-one if the function includes y values that have more than one matching x value mapped onto them.
From the graph, we can see that the function has assymptotes as the curves are approaching the axis.
Now, it's not every value of y that has a value of x mapped on to it because at say y - value of 0.2, there is no corresponding x-value.
Also, from the graph, we can see that the y-values that have a corresponding x-value don't have more than one x value mapped onto them.
Thus, the function is neither a one-to-one function or many-to-one function.
But it is a rational function since it has a graph even though it is with assymptotes.
Thus,the correct answer is option C: It is a function but it is not one-to-one.
Answer:
Step-by-step explanation:
Divide the equation by 3, subtract 9, take the square root.
3x^2 + 27 = 0
x^2 + 9 = 0 . . . . . divide by 3
x^2 = -9 . . . . . . . . subtract 9
x = ±√(-9) . . . . . . take the square root
x = ±3i . . . . . . . . . use imaginary numbers to express the root
