Answer:

in order : 4 + i , 3 − 4i , -1 − 3i , -2 + 2i

Step-by-step explanation:

The complex numbers are arranged in the following way :

1st quadrant : Real , Imaginary both positive

2nd quadrant : Real positive , Imaginary negative

3rd quadrant : Real, Imaginary negative

4th quadrant : Real negative , Imaginary positive

So, The following complex numbers according to the above rule can be arranged as :

3 − 4i : 2nd quadrant

-1 − 3i : 3rd quadrant

4 + i : 1st quadrant

-2 + 2i : 4th quadrant

Thus, in order : 4 + i , 3 − 4i , -1 − 3i , -2 + 2i

Squareroot(y-1) + 3 = y

jek_recluse [69]

Note:xy means x times y and x(y) means the same thing

so
first we get rid of square root then
make the equation equal to zero becaues if
xy=0 then x or/and y=0

squareroot(y-1)+3=y

isolate the squareroot
subtrac 3 from boht sides

squareroot(y-1)=y-3

square both sides (since they are equal, you should be able to square both sides and still make it true)

(squareroot(y-1))^2=(y-3)^2
(y-1)=(y-3)(y-3)
y-1=y^2-6y+9
subtrac y from both sides
-1=y^2-7y+9
add 1 to both sides
0=y^2-7y+10
find what two number multiply to make 10 and add to get -7
the answer is -2 and -5

0=(y-5)(y-2)
therfore
y-5=0
and/or
y-2=0

therefor
y=5 or/and 2 might work
let's try out 2
square root(2-1)+3=2
square root(1)+3=2
1+3=2
false
so 2 doesn't work

let's try 5
squareroot(5-1)+3=5
squareroot(4)+3=5
2+3=5
5=5
true

y=5

Answer:

its 28

Step-by-step explanation:

C is the longest side which is 35 ye and b is 21 yd. Then you would subtract 21^2 from 35^2 and you would get 784. Then find the square root of 784 and you would get 28 as the answer! Good luck and have a great day or night!

F(x) = 6x + 5. Work out, simplifying fully: 2f(x) + 6.

Yuki888 [10]

Replace the f(x) in the second equation will 6x + 5 so then it looks like 2(6x + 5) + 6. Then distribute so it’s 12x + 10 + 6 and then simplify to 12x + 16
