Which equation has the same solution as x^2-6x-14=0
2 answers:
B. X^2-6x. =14
Answer:
(x-3)² = 23 Option B
Step-by-step explanation:
Given quadratic is :
x² - 6x - 14 = 0
Use complete the square method
Move loose term from left side to right side.
x² - 6x = 14
add both the side square of half coefficient of x that is,
half of -6 = -3
square of -3 = 9
Add both the side 9
x² - 6x + 9 = 14 + 9
(x - 3)² = 23
this is same as (x-3)²=23 second option
That's the final answer.

Answer:
increase
Step-by-step explanation:
percentage increase = new value (5) - original value (4) /original value (4) x 100
5-4 = 1
1/4 = .25
.25 x 100 - 25%
percentage decrease = original value -new l value / original value x 100
Tricky one! Since we are not given any lengths I will use my intuition.
To find the inverse of a relation, we switch the x and y values in each point.
So the inverse would be {(4, -3), (0, -1), (0, 6).
7.C I think is the answer
