Answer:

x = 6

Step-by-step explanation:

Please write this as  y = x^2 - 12x + 7 to indicate the exponentiation.

The coefficients of these three terms are a, b and c:  1, -12 and 7.

The equation of the axis (line) of symmetry is

        -b           -(-12)

x = ---------  =  -----------  = 6

         2a           2(1)

2.5 ( y + ⅖ ) = -13<br> im really bad at math someone pls help
My name is Ann [436]

Answer:

-5.6

Step-by-step explanation:

first distribute the 2.5

also convert the 2/5 to decimal (0.4) because it's hard to work with both decimal and fraction

2.5y + 2.5*0.4 = -13

2.5y +1 = -13

y = -14/2.5 = -5.6

Alecsey [184]
One less limb than yesterday! so let’s assume like a regular human the mutant has 4 limbs. he grows another 5 and now he’s got 9 limbs. he loses 12 so 9-12 equals -3, plus 2 is -1.
