Answer:

(-1)/28

Step-by-step explanation:

Simplify the following:

((-19)/2×1/38)/7

(-19)/2×1/38 = (-19)/(2×38):

((-19)/(2×38))/7

(-19)/(2×38)×1/7 = (-19)/(2×38×7):

(-19)/(2×38×7)

The gcd of -19 and 38 is 19, so (-19)/(2×38×7) = (19 (-1))/(2 (19×2) 7) = 19/19×(-1)/(2×2×7) = (-1)/(2×2×7):

(-1)/(2×2×7)

2×2 = 4:

(-1)/(4×7)

4×7 = 28:

Answer: (-1)/28

Choose the explanation that shows why ΔADE is similar to ΔABC.

Natasha2012 [34]

Recall that a dilation with center (0, 0) and scale factor $k$ maps $(x,y)$ onto $(kx, ky)$ .

Now, triangle ADE is formed by

$A=(0,0),\quad D=(0,2),\quad E=(4,0)$

Whereas triangle ABC is formed by

$A=(0,0),\quad B=(0,4),\quad C=(8,0)$

In other words, the coordinates of B and C can be obtained by multiplying by 2 the coordinates of D and E.

This means that you get ABC from ADE by dilating with center (0,0) and scale factor 2.

What is the distance between the two points (-8,-6) and (-2,4)?

MAVERICK [17]

Answer:

$\sqrt{136}$ = 11.66 units

Step-by-step explanation:

distance between 2 points (a,b) and (c,d) = $\sqrt{(a^{2}-c^{2} ) +(b^{2}-d^{2} ) }$

= $\sqrt{((-8)^{2}-(-2)^{2} ) + ((-6)^{2}-4^{2}) }$

= $\sqrt{136}$

= 11.66 units
