Hurry 50 points for correct answer
Solve the equation. Identify any extraneous situations.
x=√6x+7

1 is a solution to the original equation. The value –7 is an extraneous solution.

7 is a solution to the original equation. The value –1 is an extraneous solution.

7 and –1 are solutions.

7 and 1 are both extraneous solutions.

"7 is a solution to the original equation. The value –1 is an extraneous solution."

Step-by-step explanation:

The equation can be solved by squaring both sides:

We can see that -1 and 7 are solutions, but make sure they are not extraneous by substituting them in the original equation:

The square root of 49 equals 7, but the square root of -1 is an imaginary number.

The correct choice is "7 is a solution to the original equation. The value –1 is an extraneous solution."

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
