Which equation has the same solution as x2 + 16x + 9 = -3?

Step-by-step explanation:

x² + 16x + 9 = - 3

x² + 16x + 12 = 0

D = 16² - 4(1)(12) = 208

√D = 4√13

= ( - 16 - 4√13 ) ÷ 2 = - 8 - 2√13 ≈ - 15.21

= ( - 16 + 4√13 ) ÷ 2 = 2√13 - 8 ≈ - 0.79

step-by-step explanation:

compare

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
