X^2 - 8x + 13 = 0
subtract 13 from both sides
x^2 - 8x = -13
-8/2 = -4, (-4)^2 = 16, add 16 to both sides
x^2 - 8x + 16 = -13 + 16
factor the left side
(x - 4)^2 = 3

Answer:
x = 9
Step-by-step explanation:
AB = 4x + 6 and BC = 7x + 15 AC is the sum of AB and BC
so 4x + 6 + 7x + 15 = 120 add like terms
11x + 21 = 120 subtract 21 from both sides
11x = 99 divide both sides by 11
x = 9
Answer:
Domain is all the possible X values on a graph
Range are all the possible Y values on a graph
Step-by-step explanation:
Example- If given a graph where on the X line goes from 0-10 and Y goes from 0-30 the domain would be all real numbers 0-10 and range would be all real numbers 0-21
