Answer

20 + units

Explanation

Perimeter is the distance all round a figure.

AB = 10. This is given in the question

AC = √((3-5)²+(4--2)²

= √(4+36)

=√40 = 6.32 units

BC = 5 - -5 = 10 units

Perimeter = AB+AC+BC

= 10+6.32+10

= 26.32 units

From the choices, we do not have an exact answer. The one that mosts suits the perimeter is 20 + units.

A line passes through the point (4,-6) and he a slope -3/4. Which is the equation of the line?

ANEK [815]

Answer:

The equation of the line is 3x + 4y + 12 = 0

Step-by-step explanation:

$given \: that \: the \: line \: passes \: through \: (4 , - 6) \\ and \: has \: the \: slope \: of \: \frac{ - 3}{4} \\ the \: equation \: of \: the \: line \: is \\ y - y1 = m(x - x1) \\ here \: x1 = 4 \: \: \: y1 = - 6 \: \: and \: m = \frac{ - 3}{4} \\ on \: substituting \: the \: values \: in \: formula \\ y - ( - 6) = \frac{ - 3}{4} (x - 4) \\ y + 6 = \frac{ - 3}{4} (x - 4) \\ 4(y + 6) = - 3(x - 4) \\ 4y + 24 = - 3x + 12 \\ 3x + 4y + 24 - 12 = 0 \\ 3x + 4y + 12 = 0$
