Solve the system by elimination. -6x + y = 0 9x - 8y = 4

Mathematics

Answer:

(4, 4 )

Step-by-step explanation:

Given the 2 equations

- 6x + 6y = 0 → (1)

9x - 8y = 4 → (2)

Multiplying (1) by 3 and (2) by 2 and adding will eliminate the x- term, that is

- 18x + 18y = 0 → (3)

18x - 16y = 8 → (4)

Add (3) and (4) term by term to eliminate x, then

2y = 8 ( divide both sides by 2 )

y = 4

substitute y = 4 into either of the 2 equations and solve for x

Substituting into (2)

9x - 8(4) = 4

9x - 32 = 4 ( add 32 to both sides )

9x = 36 ( divide both sides by 9 )

x = 4

Solution is (4, 4 )

kipiarov [429]

Answer:

Notation Rule A notation rule has the following form ry−axisA → B = ry−axis(x,y) → (−x,y) and tells you that the image A has been reflected across the y-axis and the x-coordinates have been multiplied by -1. Reflection A reflection is an example of a transformation that flips each point of a shape over the same line.

Inga [223]

Answer:

Line W'X' is 4 times longer than line WX.

Step-by-step explanation:

When we dilate a figure by a scale factor, the side length increases by that scale factor. If the length was 1 before the dilation, and the scale factor is 2, the length would be 2 after the dilation because 1*2=2. Assuming that WX and W'X' are sides of the figure because no image was provided, the dilated side should be 4 times longer.
