Answer:
A. ![y\leq \frac{1}{2}x+2](https://tex.z-dn.net/?f=y%5Cleq%20%5Cfrac%7B1%7D%7B2%7Dx%2B2)
Step-by-step explanation:
Well since it’s a solid line and it’s shaded down it should say
.
So we can cross out B and D.
And the slope by looking at the line is 1/2x.
So the answer is A.
The absolute value of B is 1 3/5 because although B is in the negatives, absolute value makes it positive.
Answer:
B. x=1+2i or x=1-2i.
Step-by-step explanation:
The equation is given as;
x²-2x+5=0
complete the square method to find value of x as;
x²-2x = -5
x²-2x + 1 = -5 + 1
x²-2x +1 =-4
( x-1 )² = -4
x-1 = ±√-4 ---------<em>where √-1 = i</em>
x-1 =± 2i
So;
x-1 = + 2i
x= 1+2i
or
x= 1-2i
x= 1-2i
