Answer:

1)24 2)36 3)240

Step-by-step explanation:

1) area of triangle = 1/2b*h so 7*4=28 28/2=14

therefore area =24

2)9*4=36

3)15*16=240

What can be concluded about the line represented in the table? Check all that apply. x y –6 –7 2 –3 8 0 The slope is 2. The slop

Stels [109]

The first thing we must do for this case is to find the equation of the line.
$y-yo = m (x-xo)
$
We have then:
$m = (y2 - y1) / (x2-x1)

m = (-3 - 0) / (2-8)

m = 1/2$
We choose an ordered pair:
$(xo, yo) = (8, 0)
$
Substituting values:
$y-0 = (1/2) (x-8)

y = (1/2) x - 4$

From here we conclude:

Intersection with y:
We evaluate x = 0 in the function:
$y = (1/2) (0) - 4

y = -4$

Slope of the line:
$m = 1/2
$

Point (-2, -5):
We evaluate the value of x = -2 and the value of y = -5
$-5 = (1/2) (- 2) - 4

-5 = -1 - 4

-5 = - 5$
The equation is satisfied.

Point (8, 0):
It is part of the table, therefore belongs to the line.

Answer:
The slope is 1/2
The y-intercept is -4.
The points (-2, -5) and (8, 0) are also on the line.

Find the distance BF for the points B(1,-1) and F(-3,5)

Nadusha1986 [10]

Use the distance formula:
 $\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Plug in the given coordinates:
 $\sqrt{(-3-1)^2 + (5-(-1))^2}$

Simplify:
 $\sqrt{(-3-1)^2 + (5+1))^2}$

$\sqrt{-4^2+ 6^2}$

$\sqrt{16+36}$

$\sqrt{52}$
You can leave it as: $\sqrt{52}$ or in decimal form as: 7.2
