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
Answer:
Step-by-step explanation:
first plug 362.50 in for y since that is our office supply expense
362.50 = 10.50x + 100
then we solve for x
362.50 = 10.50x + 100
262.50 = 10.50x
25 = x
so 25 are working in the office that month

Answer:
x = 8
y = 1
Step-by-step explanation:
First you want to substitute y in for 1 to get
2x + 4 = 20
Then subtract four to both sides to get
2x = 16
Then divide 2 by 16 to get
x = 8
and then plug the 8 into the original equation
2(8) + 4y = 20
And then solve for y!
