The value of the complex expression will be 3 + 9i. Then the correct option is C.
The complex number is the combination of the real part and the imaginary part.
Then the complex number is given as
⇒ a+bi
The complex expression is given below.
⇒ (4 + 2i) and (1 − 7i)
Then the difference between the complex number will be
⇒ (4 + 2i) - (1 - 7i)
Simplify the complex expression, then the complex expression will be
⇒ (4 + 2i) - (1 - 7i)
⇒ 4 + 2i - 1 + 7i
⇒ 3 + 9i
The value of the complex expression will be 3 + 9i.
Then the correct option is C.

Hi
2x-y=5
3x+2y=4
We need to solve 2x-y=5 for y
Now let's start by adding -2x to both sides
2x-y-2x=5-2x
-y=-2x+5
Divide both sides by -1 so we eliminate the negative sign
-y/-1=-2x+5/-1
y=2x-5
Now substitute 2x-5 for y in 3x+2y=4
3x+2y=4
3x+2(2x-5)=4
3x+4x-10=4
7x-10=4
Add 10 to both sides
7x-10+10=4+10
7x=14
Divide both sides by 7 so we can find the value for x
7x/7=14/7
x=2
Now substitute 2 for x in y=2x-5 so we can find the value for y
y=2x-5
y=(2)(2)-5
y=4-5
y=-1
Answer: (2,-1)

Answer:
at x= 0 and x= 1 and not at x= 3.
Step-by-step explanation:
We have the functions, and .
It is given that,
At x=0, x=1, and x=3,
i.e.
i.e.
i.e.
i.e. x= 0 and (x-1)= 0
i.e. x= 0 and x= 1.
Also, after plotting the graphs of both the functions, we see their intersection point are (0,1) and (1,3).
Thus, we get that at x= 0 and x= 1 and not at x= 3.
Answer:
4 hours and 40 minutes
Step-by-step explanation:
speed = distance/time
distance/speed = time
300/65 = 4.615 hours
0.615 x 60 = 36.9
= 4 hours and 40 minutes
