Question

Which equation is true when k = –12?

Answer 1

A3k – 11 = 16
3 k – 11 = 16
B–53 + 4k = 5
–53 + 4 k = 5
C
k
3 + 17 = 13
k 3 + 17 = 13
D
k
4 + 2.5 = 0.5

Answer 2

3k – 11 = 16

–53 + 4k = 5

3/k + 17 = 13


4/k + 2.5 = 0.5

Answer 3

To determine which equation is true when k = -12, we need the equation options. Please provide the equation options.

Answer 4

To determine which equation is true when k = -12, we can substitute -12 for k in each equation and see which one results in a true statement.

A) A3k – 11 = 16
A3(-12) - 11 = 16
-36 - 11 = 16 (this is not true)

B) B–53 + 4k = 5
-53 + 4(-12) = 5
-53 - 48 = 5 (this is not true)

C) Ck3 + 17 = 13
(-12)3 + 17 = 13
-36 + 17 = 13 (this is not true)

D) Dk4 + 2.5 = 0.5
(-12)4 + 2.5 = 0.5
-48 + 2.5 = 0.5 (this is not true)

None of the equations are true when k = -12.

Answer 5

To determine which equation is true when k = -12, we can substitute -12 for k in each equation and see which one results in a true statement.

A) 3k – 11 = 16
3(-12) - 11 = 16
-36 - 11 = 16
-47 = 16 (this is not true)

B) –53 + 4k = 5
-53 + 4(-12) = 5
-53 - 48 = 5
-101 = 5 (this is not true)

C) 3/k + 17 = 13
3/(-12) + 17 = 13
-1/4 + 17 = 13
-1/4 + 68/4 = 13 (this is true)

D) 4/k + 2.5 = 0.5
4/(-12) + 2.5 = 0.5
-1/3 + 2.5 = 0.5
7/3 = 0.5 (this is not true)

The equation that is true when k = -12 is C) 3/k + 17 = 13.
