Well if you use the subtraction method for elimination you get 
2x+-2y=12
Now you can times one at a time by zero and find what each equals.
2(0) +-2y=12
y=-6
2x+-2(0)=12
x=6

Answer:

b. x² + 8x + 12 =

1. use the factoring X (see attachment)

2. 6 x 2 = 12; 6 + 2 = 12

3. (x + 6)(x + 2) = 0

4. x = -6, -2

c. x² + 13x + 12 =

1. 12 x 1 = 12; 12 + 1 = 13

2. (x + 12)(x + 1) = 0

3. x = -12, -1

c. x² + x - 12 =

1. 4 · (-3) = -12; 4 - 3 = 1

2. (x +4)(x - 3) = 0

3. x = -4, 3

f. x² + 15x + 36 =

1. 12 x 3 = 36; 12 + 3 = 15

2. (x + 12)(x + 3) = 0

3. x = -12, -3

hope this helps :)

How I can answer this question, NO LINKS, If you answer correctly I will give u brainliest!
zlopas [31]

Answer:

I pick a ,  and e

Step-by-step explanation:

a - Proportional relationship maybe because the line is slanted and the first dot is on 0 then it moves five up and if it keeps going on it would end up like a multiplication chart of the 5

hope this helped

e -  x on the line is 2    , y is  5 because graph 2 then moves up five times which will result to  (x 2,y 5)

hope this helped

Someone help me with number 8
Gnesinka [82]

Answer:

The answers are...:

The common ratio is -3

the sequence of the function is 2,-6, 18, -54, 162

and

the sequence of the function model is geometric

I hope this helps ^^"

Step-by-step explanation:

the common ratio is just from the -3 itself

the sequence model is just plugging n for every term so

a(1) would equal to 2, a(2)=-6 , a(3) would equal to -18, etc

and the geometric is bc it has the exponential that has (n-1), thus it is a geometric sequence
