Answer:
<h2>B) (0, 6)</h2>
Step-by-step explanation:
If the point lies on the y-axis then the first coordinate of the point is equal 0.
(0, y) - y is any real number.
Answer:
1) D it doesn't pass the line test
2)B
3)A C F
Answer:
Step-by-step explanation:
To Differentiate A linear Function from a non-linear one we have Several rules.
1: check the Variables exponent degree of the function if the exponent is zero or 1 of the function that's the function is linear.
2: if it's not 0 or 1 and Greater than 1 than it's non linear function also if the exponent is of any negative value like -1 or -2 than it's also a non linear function. The Given function is a non linear function because the 9xy value has two variables multiplied if we add the exponent values together which are 1+1 = 2 hence proved it's a non linear function. One More Thing a graph of non linear function will be always other than that of a straight line.
Answer:

The error was done in Step E, because student did not multiply 
by the negative sign in numerator. Step E must be 
.
Second image attached
The error was done in Step C, because the student omitted the 
of the algebraic identity 
. Step C must be 
Step-by-step explanation:
First image attached
The error was done in Step E, because student did not multiply by the negative sign in numerator. The real numerator in Step E should be:
Hence, Step E must be .
Second image attached
The error was done in Step C, because the student omitted the of the algebraic identity . Step C must be
And further steps are described below:
Step D
Which according to the Quadratic Formula, represents a polynomial with complex roots. That is: (
, 
, 
)
(Conjugated complex roots)
Step E
Step F
