What are the solutions of each equation? Use a graph of the related function. a. x2 + 4 = 4 b. x2 + 16 = 0 c. x2 − 49 = 0

Step-by-step explanation:

a)  x^2 + 4 = 4 is equivalent to x^2 = 0, which has two real, rational roots:  {0, 0}

b)  x^2 + 16 has two equal, imaginary roots:  {-4i, 4i}

c)  x^2 - 49 has two different, real roots:  {-7, 7}

answer: i think one of the answer is $150 and $300?

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
