()=1 solve for x: if you could can you show steps

x = 0.787 and x = -0.565

Step-by-step explanation:

Here's how I got these answers:

(3x^2)-(x)=1 can be rewritten as the quadratic 9x^2 - x - 1 = 0.  Here a = 9, b = -1 and c = -1.  The discriminant b^2-4ac is therefore 1-4(9)(-1) = 37.  There are two real, unequal roots (values of x that make the given equation true).  They are:

             -(-1) plus or minus √37

x =      

                          -9

Simplifying, we get:

x =  (1 + √37)/9 and x = (1 - √37)/9

This results in x = 0.787 and x = -0.565

whatvare the choices

step-by-step explanation:

the distance between the school and her home is 3.6km.

12 mins = 0.2 hours = 1/5 hour

54 ÷ 3 = 18km per hour

1/5 of 18 = 3.6km per 12 mins
