Answer:
x = 4 ± 
Step-by-step explanation:
Given
(x - 12)(x + 4) = 9 ← expand the left side using FOIL
x² - 8x - 48 = 9 ( ad 48 to both sides )
x² - 8x = 57
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = 57 + 16
(x - 4)² = 73 ( take the square root of both sides )
x - 4 = ±
( add 4 to both sides )
x = 4 ± 
Answer :slope is 47 y intercept is (0,-2)
Step-by-step explanation:
Answer:
A. yes
B. yes
C. no
Step-by-step explanation:
The coordinates of each point are (x, y).
J (-2, -3)
K (0, 2)
L (1, -4)
After being scaled by 1.5 about the origin, the coordinates are (1.5x, 1.5y).
J (-3, -4.5)
K (0, 3)
L (1.5, -6)
