Which are solutions of the equation x2 – 16 = 0? Check all that apply.

x = 4,-4

Step-by-step explanation:

x^2  - 16 = 0

Add 16 to both sides,

x^2 = 16

take the square root of both sides, this will cancel out x squared,

√16 = 4, so

x = 4, -4

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
