hi ate you know crush kita <3
( ˘ ³˘)♥︎
Answer:
A, C, F.
Step-by-step explanation:
A polynomial consists of an expression that involves only non-negative integer exponents for the variable; in all of your cases, the variable is x.
So, expression A has a square root of x, that is a rational exponent.
Expression C has variables in the denominators, that is negative exponent.
Expression F has variable at the exponent.
A - bi would be the other complex zero.
When you take the sqrt when solving an equation you get a + and - solution.
Answer:
Step-by-step explanation:
(a). 270° clockwise or 90° counterclockwise:
(x, y) --------> ( - y, x )
(b). 270° counterclockwise or 90° clockwise:
(x, y) ---------> ( y, - x )
Answer:
y = 2x+7
Step-by-step explanation:
y = mx + c
m = slope
c is the y intercept
so
y = 2x+ 7
