Question

What are the solutions to the following system of equations?
y = x2 + 12x + 30
8x – y = 10

Answer 1

I won't give you the answer bgut I'll help you solve it. First, isolate your Y's.

Answer 2

HInt:

8x - 10 = x^2 + 12x + 30

Answer 3

Well, I guess someone will do it for you.

Answer 4

\[0=x^2+4x+20\]

Answer 5

It was a hint. She still has to find the solutions

Answer 6

WolframAlpha to the rescue!!

Answer 7

Wow, really

Answer 8

and its giving weird answers .-.

Answer 9

I mean x² + 4x + 40 = 0

Answer 10

yea thats what i put

Answer 11

its giving complex solutions

Answer 12

@Chlorophyll, I thought you were trying to give someone plus 40 likes

Answer 13

yummydum, do b^2-4ac . If it is negative, solutions will be complex

Answer 14

@Hero Not anymore ;)

Answer 15

its negative so does that mean there are no real solutions

Answer 16

Yup

Answer 17

So do you need to find complex roots?

Answer 18

no its multiple choice n i picked no real solutions :)

Answer 19

Look like happy ending :D

Answer 20

What is the solution to the following system of equations?
y = x2 + 10x + 11
y = x2 + x – 7

(–2, –5)

(2, –5)

(–2, 5)

(2, 5

Answer 21

lol @Chlorophyll if only

Answer 22

@Hero i know its A or C

Answer 23

Open the new post for each of question!
Anyway, equal the 2 equations!

Answer 24

its A?

Answer 25

it is ^_^

Answer 26

Correct, A!

Answer 27

@yummydum, if you do the math, you'll know there's only one possible solution.

Answer 28

i did

Answer 29

i did-ed it all by myself ^_~
