Answer:
Q3: x1=2+i, x2=2-i Q4: x1=-3/2+i, x2=-3/2-i
Step-by-step explanation:
( ±
) /
= (
x1= 2+i
x2= 2-i
( ±
) /
= (-6 ±
)/4= (-3 ± i)/2
x1 = -3/2 +i
x2 = -3/2 -i
Write the some of the numbers as the product of the greatest common factor and another sum 55 + 66

Answer:
B
Step-by-step explanation:
Hi there!
We are given the points (-1,2) and (3,3) and we need to find the slope.
The formula for slope calculated from two points is , where (
,
) and (
,
) are points
since we have two points, we can substitute them into the formula, but let's label their values to avoid any confusion
=-1
=2
=3
=3
now substitute into the formula (m is the slope); remember: we have a negative number in this, so we'll be subtracting a negative.
m=
simplify
m=
m=
so <u>B </u>is your answer
Hope this helps! :)
