Question 2 of 10
azamat

Answer:

C

Step-by-step explanation:

THe equation given is

2x+2y=16

y=x-4

We put 2nd equation in first equation and first solve for x:

2x+2y=16\\2x+2(x-4)=16\\2x+2x-8=16\\4x=16+8\\4x=24\\x=\frac{24}{4}\\x=6

Now, since we know y = x - 4, we substitute x = 6 and get y:

y = x - 4

y = 6 - 4

y =2

The correct ordered pair is (6,2), answer choice C

B^2-4b-12=0 please help me
Olegator [25]

Answer:

Step-by-step explanation:

 b² - 4b - 12 = b² - 6b + 2b - 2*6

=b*(b -6) + 2*(b - 6)

= (b - 6) (b + 2)

 b² - 4b - 12 = 0

(b - 6) (b + 2) = 0

b - 6 = 0     or b + 2 = 0

b = 6           or b =  -2
