RST has vertices R(0,0), S(10,5), and T(5,-5). R’S’T’ is the image of RST after a dilation with center (0,0) and scale factor 1/
AysviL [449]

The coordinates of the point S' is (2,1)

Explanation:

Given that the RST has vertices R(0,0), S(10,5) and T(5,-5)

The image R'S'T' is the image of RST after a dilation with center (0,0) and scale factor \frac{1}{5}

We need to determine the coordinates of the point S'

The coordinates of S' can be determined by multiplying both the x and y - coordinates of the point S with the scale factor \frac{1}{5}

Let us consider the x - coordinate of the point S and multiply it with the scale factor \frac{1}{5}

Thus, we have,

x - coordinate of the point S' is given by

10 \times \frac{1}{5}=2

Thus, the x - coordinate of the point S' is 2

Similarly, the y - coordinate of the point S' can be determined by multiplying the point S with the scale factor \frac{1}{5}

Thus, we have,

The y - coordinate of the point S' is given by

5\times\frac{1}{5}=1

Thus, the y - coordinate of the point S' is 1

Hence, the coordinates of the point S' is (2,1)

One exterior angle of a regular pentagon has a measure of (2x)”. What is the value of x?
USPshnik [31]

Answer:

x = 36°

Step-by-step explanation:

The sum of the exterior angles of a pentagon is always 360°. Since the pentagon is regular, meaning that all of its sides and interior angles are congruent, we know that all of the exterior angles are also congruent. Since a pentagon has 5 sides, we know that there are 5 congruent exterior angles, therefore:

5 * 2x = 360

10x = 360

x = 36°

(4x + 18) value of X
liubo4ka [24]

Answer:

x = (-9)/2 or decimal x = -4.5

Step-by-step explanation:

Solve for x:

4 x + 18 = 0

Subtract 18 from both sides:

4 x + (18 - 18) = -18

18 - 18 = 0:

4 x = -18

Divide both sides of 4 x = -18 by 4:

(4 x)/4 = (-18)/4

4/4 = 1:

x = (-18)/4

The gcd of 18 and 4 is 2, so (-18)/4 = (-(2×9))/(2×2) = 2/2×(-9)/2 = (-9)/2:

Answer:  x = (-9)/2
