Find the area of the shape someone please help me:):)

Anettt [7]

Answer:

31.5

Step-by-step explanation:

You have to break the shape up into a triangle and a rectangle

Area of a Triangle:

A=1/2(b)(h)

=1/2(7)(3)

=1/2(21)

=10.5

Area of Rectangle:

A= (b)(h)

=(7)(3)

=21

Area of Total Shape:

10.5 + 21

=31.5

Find the midpoint of the line segment whose endpoints are (-2, 5) and (6, -9).

Katen [24]

We know that when $A=(x_A,y_A)$ and $B=(x_B,y_B)$ the midpoint of the line segment AB is given by:

$M=\left(\dfrac{x_A+x_B}{2},\dfrac{y_A+y_B}{2}\right)$

Here $A=(-2,5)$ and $B=(6,-9)$ so:

$M=\left(\dfrac{x_A+x_B}{2},\dfrac{y_A+y_B}{2}\right)=\left(\dfrac{-2+6}{2},\dfrac{5+(-9)}{2}\right)=\\\\\\=\left(\dfrac{4}{2},\dfrac{5-9}{2}\right)=\left(2,\dfrac{-4}{2}\right)=\boxed{\left(2,-2\right)}$

Find the equation of the line that is perpendicular to y = 2x + 8

Natasha2012 [34]

Answer:

$\boxed {\boxed {\sf B. \ y= - \frac{1}{2} x-4}}$

Step-by-step explanation:

We are given the line y=2x+8. It is in slope-intercept form or y= mx+b, where m is the slope and b is the y-intercept.

The slope of the line is 2.

We want to find the equation that is perpendicular. Perpendicular lines have negative reciprocal slopes.

1. Negate

Negate the slope, or switch the sign
(+) 2 --> -2

2. Reciprocal

Flip the numerator and denominator of the slope.

-2/1 --> -1/2

The perpendicular slope is -1/2, so the correct equation must be B.
