Answer:

slope = - $\frac{3}{2}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 6, 4) and (x₂, y₂ ) = (2, - 8)

m = $\frac{-8-4}{2+6}$ = $\frac{-12}{8}$ = - $\frac{3}{2}$

The diagram shows a 7cm x 6cm rectangle-based pyramid all the diagonal sides - TA TB TC and TD are length 10cm M is the midpoint

dedylja [7]

Given:

The base is a rectangle of dimension 7 cm×6 cm.

The length of each diagonal side = 10 cm

To find the height of MT.

Formula

By Pythagoras theorem we get,

$h^{2} = l^{2} + b^{2}$

where, h be the hypotenuse

b be the base and

l be the height.

Now, in this diagram,

The perpendicular distance of M from BC = 3 cm

Slant height = 10 cm

Taking, b = 3 and h = 10 we get,

$10^{2} = l^{2} + 3^{2}$

or, $l^{2} = 10^2-3^2$

or, $l = \sqrt{100-9}$

or, $l = 9.5$

Hence,

The height of MT is 9.5 cm.

6x+2y= 6x+2y= \,\,16 16 2x-2y= 2x−2y= \,\,32 32

Ivanshal [37]

Answer:

x = 6, y = -8

Step-by-step explanation:

First we take the equations side by side and put them like this:

6x + 2y = 16

+ 2x - 2y = 32

8x = 48

Then solve for x.

x = 6

Then insert x back into either equation

2(5) - 2y = 32

10 - 2y = 32

solve for y,

y = -10
