7(-2x +4) = -4x \\\\\implies -14x + 28 = -4x \\\\\implies -14x +4x = -28\\\\\implies -10x = -28\\\\\implies x = \dfrac{-28}{-10} = \dfrac{14}5

Answer: x = 14/5

Explanation:

-14x + 28 = -4x
-14x = -4x - 28
-14x + 4x = -28
-10x = -28
X = 14/5

Gragh the image of the figure after a dilation with a scale factor of 1/4 centered at (5, -5) please help
svetoff [14.1K]

Answer:

See attached diagram

Step-by-step explanation:

Triangle ABC has vertices A(9,3), B(-7,-5) and C(-3,7).

The dilation with a scale factor of 1/4 centered at (5, -5) has the rule

(x,y)\rightarrow \left(\dfrac{1}{4}x+\dfrac{15}{4},\dfrac{1}{4}y-\dfrac{15}{4}\right)

Then

A(9,3)\rightarrow A'\left(\dfrac{1}{4}\cdot 9+\dfrac{15}{4},\dfrac{1}{4}\cdot 3-\dfrac{15}{4}\right)=A'(6,-3);

B(-7,-5)\rightarrow B'\left(\dfrac{1}{4}\cdot (-7)+\dfrac{15}{4},\dfrac{1}{4}\cdot (-5)-\dfrac{15}{4}\right)=B'(2,-5);

C(-3,7)\rightarrow C'\left(\dfrac{1}{4}\cdot (-3)+\dfrac{15}{4},\dfrac{1}{4}\cdot 7-\dfrac{15}{4}\right)=C'(3,-2).
