Choose the correct discriminant, then write the type and number of roots that it
indicates in the blank provided.
3x + 6 = -6x2

3

Step-by-step explanation:

Order of Operations; PEMDAS  

Parentheses  

Exponents  

Multiplication & Division (Left to Right) (ex: 10x2÷5) You would do whatever comes left for Multiplication or Division.  

Addition & Subtraction (Left to Right) (ex: 10-2+5) You would do whatever comes left for Addition & Subtraction.

3x+6 =

(9+6=15)

(6x2=12)

(12-15=3)

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
