Answer:
x = - 7, x = 1
Step-by-step explanation:
Given
x² + 6x = 7
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 7 + 9
(x + 3)² = 16 ( take the square root of both sides )
x + 3 = ± = ± 4 ( subtract 3 from both sides )
x = - 3 ± 4
x = - 3 - 4 = - 7
x = - 3 + 4 = 1
Solution set = { - 7, 1 }
Answer:
Explanation:
part A identification for slope:
comparing with slope intercept form: y = mx + b
we can find that here the slope is
part B, solving the equation:
if the line is parallel, then the slope will be same.
given coordinates: ( - 10, 1 )
using the equation:
y - y₁ = m( x - x₁ )
Extra information:
check the image below. this proves that the line is parallel and passes through point (-10, 1). the blue line is question line and red the answer line.
