Which is a counterexample to this conjecture?

2 answers:

3 0

The answer is C.

33,21,and 15 are all composite numbers. Meaning that they had factors other than 1 and themselves. 13 is a prime number because 13 only factors are 1 and itself.

<span>C. 6 + 7 = 13</span>
because 6 and 7 are consecutive integers, but 13 is not a composite number.

Answer:

X= -2

Step-by-step explanation:

Given: 16 = -4(x - 1) + 4

Solution:

Subtract 4 from both sides

12 = -4(x -1)

Divide -4 on both sides

-3 = x - 1

Add -1 on both sides

x = -2
