Answer:

C'(4,4)

Step-by-step explanation:

The dilation of quadrilateral ABCD over the origin by a scale factor of 2 has the rule

(x,y)→(2x,2y)

So,

A(-3,-1)→A'(-6,-2)
B(-1,1)→B'(-2,2)
C(2,2)→C'(4,4)
D(3,-2)→D'(6,-4)

Hence, the coordinates of the image point C' are (4,4) (see attached diagram for details)

Answer:

The coordinates of C' = (4,4)

Step-by-step explanation:

The coordinates of C can be found by looking at the graph,

Coordinates of C = (2,2)

ABCD is dilated by a factor of 2 to get A'B'C'D'.

So, the coordinates of C' will be found by multiplying the coordinates of C by 2.

C' = (2*2,2*2)

C' = (4,4)

So, The coordinates of C' = (4,4)

Let point L be between M and N on MN. Given that MN=31, ML= h-15 and LN = 2h-8. Find LN.

shtirl [24]

Given that point L is between M and N on MN. Then
MN = ML + LN
31 = h - 15 + 2h - 8 = 3h - 23
3h = 31 + 23 = 54
h = 54/3 = 18

Therefore, LN = 2(18) - 8 = 36 - 8 = 28.

Eight times the sum of 8 and some number is 17. What is the number?

OverLord2011 [107]

Edited answer: The number is: "- 6" .
_______________________________________________

8 (8 + x) = 16 ;

in which "x" represents the number for which to be solved ;

8*8 + 8*x = 16 .

Edit: 64 + 8x = 16 ;

Subtract "64" from each side of the equation:

Edit: 64 + 8x − 64 = 16 − 64 ;

to get: 8x = - 48 ;

Divide EACH SIDE of the equation by "8" ; to isolate "x" on one side of the equation ; and to solve for "x" ;

Edit: 8x / 8 = -48 / 8 ;

Edit: x = - 6 .
______________________________________________
The number is: "- 6" .
______________________________________________
Let us check our answer, by plugging in "-6" for "x" in the original equation:
______________________________________________
8 (8 + x) = 16 ;

→ 8 [8 + (-6) ] =? 16 ?? ;

→ 8 (8 − 6 ) =? 16 ?? ;

→ 8 (2) =? 16 ?? ;

→ 16 = ? 16 ?? Yes!
