Answer:
Option A
Step-by-step explanation:
I found it using a calculator online. Its called Desmos Graphing Calculator. Hopefully it can help in the future!
Answer:
C and E
Step-by-step explanation:
Recall that according to the complex conjugate theorem, if P(x) is a polynomial function with real coefficients, and a+bi is an imaginary root of P(x), then its conjugate (i.e a-bi) must also be a root.
Here we see that 2 of the given roots are imaginary : i and 2+i
by the theorem given above, the conjugates of these must also be roots
i.e -i and 2-i
- Triangle Inequality Theorem: States that the sum of any two sides of a triangle is greater than the length of the third side;

So for this, we are applying the triangle inequality theorem. If any of the inequalities are not true, then this cannot be a triangle. (Let A = 7.7, B = 4.0, and C = 1.7)

<u>Since the second inequality is false, these lengths cannot form a triangle.</u>
He assumes that 60-x and 2x-6 are vertical angles, so he equated these two expressions.
60-x=2x-6
60+6=2x+x
66=3x
x=22
Answer:
if you're talking 20 cents, then 4, if you're talking dollars, then 400.
tell me pls if you want an explanation.
