BRAINLIEST HELP The function f(x) = –1∕3x2 is shifted down one unit. Which of the following function equations represents this translation?
A) f(x) = –1∕3x2 + 1
B) f(x) = –1∕3(x + 1)2
C) f(x) = –1∕3(x – 1)2
D) f(x) = –1∕3x2 – 1

Pls . yeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeet

The ksp expression for the system pbcl2(s) pb+2(aq) + 2 cl-(aq) is: [pbc12][pb+2][2cl-] [pb+2][cl-]2 [pb+2][2cl-]2 [pbcl2][pb+2][cl-]2 [pb+2][2cl-]2[pbcl2]

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
