(2 − 3i) + (x + yi) = 6
We add the left hand side
(2+x) + (-3+y)i = 6
6 can be written in a+ib
6 can be written as 6 + 0i
(2+x) + (-3+y)i = 6 +0i
Now we frame 2 equations
2 + x= 6
-3 + y =0
Solve the first equation
2 + x = 6
Subtract 2 from both sides
x = 4
solve the second equation
-3 + y =0
Add 3 on both sides
y= 3
So x+yi is 4+3i
Answer:
44
Step-by-step explanation:
The sum of the ratios is 6 + 2 + 3 = 11
Let b = total number of boots sold last week
If 24 football boots are sold, the equation representing this =
6/11 x b = 24
To solve for b, divide both sides by 11/6
b = 44 = total number of boots sold last week
Step-by-step explanation:
So
WHOLE thing's rule (x,y)
(-1,6) one left 6 up
(1, -6) one right 6 down
(6,-1) six right one down
All you have to do is add exponents when multiplying like monomials. So it's just 4^2
