Answer:

1947 units^2

Step-by-step explanation:

you can split it up into different sections of rectangles.

the first one is 25x39= 975

The second section is the connector which you do

43-25=18

and you do 39-27=12 and then

you multiple 18x12 which equals 216

and the final section you do 24+12=36

and 36x21=756

and finally you add them all up to equal 1947 units^2

This table gives a few (x, y) pairs of a line in the coordinate plane. What is the x-intercept of the line?

PIT_PIT [208]

Answer:

Step-by-step explanation:

The x-intercept of a line is the value of x that makes y=0.

A line can be expressed in its slope-intercept form:

y=mx+b

Once determined the equation of the line, the x-intercept can be calculated by setting y=0 and solving for x.

Let's find the slope of the line.

Suppose we know the line passes through two points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Let's pick the first two points of the table (-94,24) (-74,18). The slope is:

$\displaystyle m=\frac{18-24}{-74+94}=\frac{-6}{20}=-\frac{3}{10}$

The equation of the line is:

$\displaystyle y=-\frac{3}{10}x+b$

Now use one of the points to find b, for example (-94,24):

$\displaystyle 24=-\frac{3}{10}\cdot (-94)+b$

Operating:

$\displaystyle 24=\frac{141}{5}+b$

Solving:

$b=24-\frac{141}{5}=-\frac{21}{5}$

The complete equation of the line is:

$\displaystyle y=-\frac{3}{10}x-\frac{21}{5}$

To find the x-incercept, set y=0 and solve:

$\displaystyle 0=-\frac{3}{10}x-\frac{21}{5}$

$\displaystyle x=\frac{\frac{21}{5}}{-\frac{3}{10}}=-\frac{21}{5}\cdot \frac{10}{3}$

x=-14

If M <span>is the midpoint of AB then AB = 2AM

8x - 6 = 2(3x + 3)
8x - 6 = 6x + 6
8x - 6x = 6 + 6
2x = 12
x = 12/2
x = 6

AM = 3x + 3 = 3*6 + 3 = 18 + 3 = 21 units
