Rearrange this expression into quadratic form, a x 2 + b x + c = 0 , and identify the values of a , b , and c .

completed question:Rearrange this expression into quadratic form, a x 2 + b x + c = 0 , and identify the values of a , b , and c .

a=5, b=1, c=-85

Step-by-step explanation:

0.2(85-x) =

17-0.2x=

=17-0.2x

+0.2x-17=0

multiply through by 5

+x-85=0

comparing this equation to the general quadratic equation;

+bx+c=0

a=5, b=1, c=-85

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
