Answer:
±11.18
Step-by-step explanation:
the function is:
and to find the roots we need to find which values of 
makes the function result in zero:
solving for :
A square root has two solutions, one positive and one negative, so the solutions are:
±
≈ ±11.18
the roots of the quadratic equation are +11.18 and -11.18
Answer:
A and B
Step-by-step explanation:
An equivalent system of equation is found by adding or subtracting the second equation or when any multiple of both equations are added or subtracted to each other.
Let us see part by part.
A.
Y = x - 6
Please let me know if you need explanation.
Answer:
x = 6
Step-by-step explanation:
simplify both sides: 1 + x = 2x - 5
subtract x from both sides: 1 = x - 5
add 5 to each side: 6 = x
