Answer: C) A = 6, B = -15

Step-by-step explanation:

In order to have infinitely many solutions, you must end up with 0 = 0 when adding the equations together.

4x - Ay = 15

-4x + 6y = B

(6 - A)y = 15 + B

↓ ↓

6 - A = 0 15 + B = 0

6 = A B = -15

Which one of the triangles shown is the image of the other triangle after dilation?What are the coordinates of the center of dil

Tanya [424]

Answer:

a) ΔF'G'H' is the image of ΔFGH

b)Center of dilation (7,-1)

c) Scale factor: $\frac{1}{2}$

Step-by-step explanation:

Question a

Since the smaller triangle is named F'G'H', it means that, it is the image of triangle FGH.

Question B.

To find the center of dilation, draw straight lines through any two corresponding points.

The straight lines will meet at (7,-1).

This is called the center of dilation.

See graph in attachment.

Question c

The scale factor of the dilation is given by;

$k=\frac{|F'G'|}{|FG|}$

$k=\frac{\sqrt{(4-5)^2+(1-5)^2}}{\sqrt{(3-1)^2+(3-11)^2}}$

$k=\frac{\sqrt{1+16}}{\sqrt{4+64}}$

$k=\frac{\sqrt{17}}{\sqrt{68}}$

$k=\frac{\sqrt{17}}{2\sqrt{17}}$

$k=\frac{1}{2}$

What's 4 (-x + 1 ) = -2 (x + 2) ?

alexira [117]

Answer:

x = 4

Step-by-step explanation:

Simplify then isolate x

4 (-x + 1 ) = -2 (x + 2) Distribute across brackets

-4x + 4 = -2x - 4 Add 2x to both sides

-2x + 4 = -4 Subtract 4 from both sides

-2x = -8 Divide both sides by -2

x = 4
