The coordinates of quadrilateral VWXY are given below. Find the coordinates of its image after a dilation with the given scale f

Lapatulllka [165]

Answer:

The coordinates of its image after dilation by a scale factor of 2 will be:

V'(12, 4)

W'(-4, 8)

X'(-6, -10)

Y'(6, -10)

Step-by-step explanation:

Given the quadrilateral VWXY

V(6, 2)

W(-2, 4)

X(-3, -5)

Y(3, -5)

A dilation by a scale factor of 2 means every coordinate of the original quadrilateral gets multiplied by the scale factor (x2).

<u>Using the formula of dilation by a scale factor of 2</u>

Dilation with scale factor 2, multiply by 2

(x, y) → (2x, 2y)

Thus, the coordinates of its image after a dilation will be:

(x, y) → (2x, 2y)

V(6,2) → (2(6), 2(2)) = V'(12, 4)

W(-2, 4) → (2(-2), 2(4)) = W'(-4, 8)

X(-3, -5) → (2(-3), 2(-5)) = X'(-6, -10)

Y(3, -5) → (2(3), 2(-5)) = Y'(6, -10)

Therefore, the coordinates of its image after dilation by a scale factor of 2 will be:

V'(12, 4)

W'(-4, 8)

X'(-6, -10)

Y'(6, -10)

4x^2 + 36 / 4x × 1 / 5x

stich3 [128]

Given with a polynomial 4X² + 36/4X *1/5X, we can combine terms with the same power. First, let us perform multiplication of the 2nd and 3rd terms such as the given become 4X² + 36/20X². Then, we can reduce 36 and 20 by 4 and the result is 4X² + 9/5X². We can now proceed combining the terms since they have same power and result will be same as below:
(20X^4 + 9)/5X²
