Mathematics
1 answer:
Semenov [28]3 years ago
4 0

Answer:

D

Step-by-step explanation:

y=2x²+2x+1.... i

y=2x+3......... ii

Equating i and ii,

2x²+2x+1=2x+3

2x²+1-3=0

2x²-2=0

x²-1=0

x=1 or -1.

From ii, if x=1,y=5

If x=-1, y=1.

The points are (-1,1) and (1,5)

2x + 8y = 5<br> 24x – 4y = –15
slega [8]

2x + 8y = 5

2/ 24x - 4y = -15

2x + 8y = 5

48x - 8x = -30

+

--------------------------

50x = -25

x = -1/2

2 * -1/2 + 8y = 5

-1 + 8y = 5

8y = 6

y = 6/8

y = 3/4

x = -1/2 y = 3/4

If (2 − 3i) + (x + yi) = 6, what is x + yi?
Soloha48 [4]

(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
