Answer:
15.60 times 100 divided by 390=4%
Step-by-step explanation:
Answer:
the slope is stepper and the line is shifted up
21x -15 + 5 = 10x - 5
21x -5 = 10x
11x = 5
x = 5/11
Completing the square is a method used to solve a quadratic equation by changing the shape of the equation so that the left side is a perfect square trinomial.
The following equation makes more sense to solve it complete squares:
x² + 20x = 52
We have then:
x² + 20x + (10) ^ 2 = 52 + 100
(x + 10) ² = 152
Answer:
The most sense to solve by completing the square is for:
B) x² + 20x = 52
Answer:
(-1,9)
Step-by-step explanation:
coortinate point is (-9,-1)
use formula
(x,y)=(y,-x)
(-9,-1)=(-1,9)
