Solve x2 −6x = −5 by completing the square. show all work for the steps below.
(a) for x2 −6x c+ = − +5 c , what value of c is used to complete the square?
(b) substitute your value for c in part 2(a). then complete the square to rewrite the equation as the square of a binomial. show your work.
(c) solve for x. show your work.
if you can figure out what the c is all about and what not congrats and you for the if you can

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
