Write an equation that passes through (4,-3) and is perpendicular to y=-2x-4

Mathematics

makkiz [27]1 year ago

The point is (4,-3) and is perpendicular to y=-2x-4.

The slope is given , m=-2.

For the perpendicular line, the slope is

m_1\times m_2=-1m_1\times-2=-1m_1=\frac{1}{2}

Now, then the general equation is

y-y_1=m(x-x_1)

Substitute the values.

y-(-3)=\frac{1}{2}(x-4)y+3=\frac{1}{2}(x-4)y=\frac{1}{2}x-\frac{4}{2}-3y=\frac{1}{2}x-2-3y=\frac{1}{2}x-5

Hence the equation is determined as

y=\frac{1}{2}x-5

If f(x) = 2x - 9, which of the following are correct? Select all that apply. f(-1) = -11 f(2) = 5 f(3) = -3 f(0) = -9 f(-3) = 15
Yuri [45]

f(-1) = -11 and f(3) = -3 . these functions are true .

What does a math function mean?

  • A relationship between a group of inputs and one output each is referred to as a function.
  •  A function is an association between inputs in which each input is connected to precisely one output.
  • A domain, codomain, or range exists for every function. f(x), where x is the input, is a common way to refer to a function.
  • In mathematics, a function is an expression, rule, or law that establishes the relationship between two variables (the dependent variable).

given function  f(x) = 2x - 9

   f(-1) = -11 ⇒ x = -1 put in function

                       f( -1 ) = 2 * -1 - 9  ⇒ - 11

    f(2) = 5   ⇒ x = 2 put in function

                    f( 2 ) = 2 * 5 - 9 = 1

    f(3) = -3  ⇒  x = 3 put in function

                     f ( 3 ) = 2 * 3 - 9 = -3

       f(-3) = 15   ⇒  x =  -3 put in function

                     f( -3) = 2 * -3 - 9 = - 15
