Answer:

D) (4,5)

Step-by-step explanation:

Vertex E was dilated by 1/2 because 8/2 = 4. Thus, you will divide all the other coordinates by the same scale factor.

Answer:

as you can see in both triangles, comparing to each other, x = 90 angle

w = 52, because when 90 + 38 + w = 180 for a triangle

z=10yd

Find the value of r in (4,r),(r2) so that the slope of the line containing them is -5/3 A.-1/7 B-7. C 1/7 D. 7
inessss [21]

Answer:

Option D (7).

Step-by-step explanation:

The formula for gradient of the straight line is given by:

m = (y2 - y1)/(x2 - x1); where (x1, y1) and (x2, y2) are two fixed points on the straight line. It is given that (x1, y1) = (4, r) and (x2, y2) = (r, 2). The gradient of the straight line is given by -5/3. To find the value of r, simply substitute all the values in the gradient equation. Therefore:

-5/3 = (2 - r)/(r - 4).

Cross Multiplying:

-5*(r - 4) = 3*(2 - r).

-5r + 20 = 6 - 3r.

-2r = -14.

r = 7.

Therefore, Option D is the correct answer!!!

liubo4ka [24]

Answer:

The element you add is      b^2 / 4a

Step-by-step explanation:

The element you add is      b^2 / 4a

Remember that

a x^2 + bx +c  \\= a ( x^2 +(b/a)x ) + c

So, in order to complete the square you add   (b/2a)^2

But when you multiply times  a   you get

b^2 / 4a
