Write the equation of the line passing through (-3, 4) and normal to -2x + 7y = -3. (Note: normal means perpendicular)
MArishka [77]

Answer:

The answer to your question is     y = -7/2x -13/2

Step-by-step explanation:

Point = (-3, 4)

Line   -2x + 7y = -3

Process

1.- Solve equation for y to find the slope of the perpendicular line

                  7y = 2x - 3

                    y = 2/7 x - 3/7

slope = 2/7

Slope of the perpendicular line = -7/2

2.- Find the equation of the new line

                   y - y1 = m(x - x1)

                   y - 4 = -7/2(x + 3)

                   y - 4 = -7/2x - 21/2

                   y = -7/2x - 21/2 + 4

                   y = -7/2x -21/2 + 8/2

3.- Result

                   y = -7/2x -13/2

A polynomial function g(x) with integer coefficients has a leading coefficient of 1 and a constant term of
mart [117]

Answer:

+1, -1, +11, -11

probably written with a +- symbol:

+-1, +-11

Maybe (silly) written like fractions:

+- 1/1, +- 11/1

Step-by-step explanation:

First list the factors of the leading coefficient. Here its 1. So we're going to use positive and negatives of the factors of 1, which is just +/- 1 . These numbers are going to go on the bottom of a fraction.

Next look for the factors of the constant, here it's 11

So that gives us

+/- 1, +/- 11 . These will go on the top of a fraction. (A fraction is a rational expression, that's why the name)

Then make all the combinations of

factors of constant

OVER

factors of leadingcoeff

So, we find

+/- 1, +/- 11
