Find the equation of the line. A line that is perpendicular to the graph of 3x +2y =6 and contains the point (6,-3)
aniked [119]

9514 1404 393

Answer:

  2x -3y = 21

Step-by-step explanation:

The perpendicular line will have an equation with the x- and y-coefficients swapped and one of them negated. The constant will be the value that makes the equation true at the given point.

  3x +2y = 6 . . . . . given equation

  2x -3y = c . . . . . . coefficients swapped, one negated

  2(6) -3(-3) = c = 21 . . . . . the value of c for the given point

The desired equation is ...

  2x -3y = 21

Which shows the correct substitution of the values a, b, and c from the equation 0 = – 3x2 – 2x + 6 into the quadratic formula?
ZanzabumX [31]

Answer:

shows correct substitution of the values a, b, and c  from the given quadratic equation    into quadratic formula.

Step-by-step explanation:

Given: The quadratic equation

We have to show the correct substitution of the values a, b, and c from the given quadratic equation    into quadratic formula.

The standard form of quadratic equation is  then the solution of quadratic equation using quadratic formula is given as

Consider the given  quadratic equation

Comparing with general  quadratic equation, we have

a = -3 , b = -2 , c = 6

Substitute in quadratic formula, we get,

Simplify, we have,

Thus,  and x_{2}=\frac{2-\sqrt{76} }{-6}

Simplify, we get,

Thus,  shows correct substitution of the values a, b, and c  from the given quadratic equation    into quadratic formula.

Afina-wow [57]

Answer:

major arc CEB = 320°

Step-by-step explanation:

arc BF = 140°

arc CE = 140°

arc CB = arc EF

arc CB + arc EF = 360-280 = 80

arc CB = 40°

major arc CEB = 360 - 40= 320°
