Answer:
2i or -2i
Step-by-step explanation:
2x² = -8 First, clear x.
x² = -8/2 Solve
x² = -4 Now, eliminate the square of x by solving the square root of -4.
x = √-4
x = 2i or -2i Is an imaginary number.
Answer: $0.20
Step-by-step explanation:
There are 16 ounces in 1 pound, so divide $3.20 by 16 to get the price of dollars/ounce
3.20/16 = $0.20/ounce
Answer:
You have vertical asymptotes on x=-4,-2
Step-by-step explanation:
This question is very simple. Since you have a denominator all you need to do is factor the bottom and find the zeros. When you factor the bottom of the equation you should get (x+4)(x+2). Now you have to set the bottom equal to zero to find the zeros. This means (x+4)=0 and (x+2)=0 So you get two answers x=-4 and x=-2 Therefore your two vertical asymptotes are on x-4,-2
