D = sqrt (x2 - x1)^2 + (y2 - y1)^2
(1,-2)(10.-4)

d = sqrt (10 - 1)^2 + (-4 - (-2)^2
d = sqrt (9^2 + (-4 + 2)^2
d = sqrt (9^2 + (-2^2)
d = sqrt (81 + 4)
d = sqrt 85
d = 9.2

What is the image point of (-6, 9) after a translation left 4 uints and down 1 unit?
Alex17521 [72]

Answer:

(-10,8)

Step-by-step explanation:

So our original point is (-6,9).

A translation of 4 units to the left means that the x-value would go left by 4. In other words, we subtract 4 to -6. We subtract because going to the left means that it's going to the negative direction.

A translation of down 1 unit means that the y-value would go down by 1. In other words, we subtract 1. Again, we subtract because going downwards means that it's going to the negative direction.

Therefore, the new point would be:

(-6-4,9-1)\\=(-10,8)

Hello there!

( (2^2*3^2x^2) -  25) \\ \\  Factoring:  \boxed{36x2-25} \\ \\ (PROOF): \\ \\  (A+B) * (A-B) = \\
         A2 - AB + BA - B2 = \\
         A2 - AB + AB - B2 =  \\
         A2 - B2 \\ \\

Your final answer would be (<span> (6x + 5) • (6x - 5)).

Your correct answer would be (option d).

I hope this helps you!</span>
