D.

Look at top left coordinate (2,-1)
Eight units left = (2-8,-1) = (-6,-1)
Reflection across x axis means change in y
(-6,-1) to (-6, 1) :)

Determine the x- and y-intercepts of the graph of y=−1/3x+3 .

Alinara [238K]

Answer:

x intercept

$y = 0 \\ 0 = \frac{1}{3} x + 3 \\ \frac{1}{3} x = - 3 \\ x = - 9$

y intercept

$x = 0 \\ y = \frac{1}{3} \times 0 + 3 \\ y = 3$

Given a dilation around the origin, what is the scale factor K? Do, K = (20,16) → (-5,-4)

Rudik [331]

Answer:

Scale factor, K = -1/4

Step-by-step explanation:

Dilation of any image changes its size and the shape remains same.

The scale factor is the ratio of dilated image to original image.

Dilation rule: (x, y) → (kx, ky), where k is the scale factor.

It means k = x₂/x₁ or y₂/y₁

K = -5/20 = -1/4 or K = -4/16 = -1/4.

The negative value of scale factor (K) indicates dilations with 180 degree rotation of the dilated image.

Hence the scale factor is K = -1/4.

List the following numbers in order from least to greatest. a) 3.5× 10/3 B) 3.5× 10-2 C) 5.3 × 10/3

Crazy boy [7]

Answer:

$3.5*10^{-2}, 3.5*10^3, 5.3*10^3$

B, A, C

Step-by-step explanation:

This is scientific notation. The numbers $3.5 * 10^3\\3.5 *10^{-2}\\5.3 * 10^3$ can be ordered least to greatest by looking at their digits and exponents. Since a -2 as an exponent is present, this means this is a small decimal and is the least. 3.5 and 5.3 have the same exponent of 3 but 5.3 is greater than 3.5 so its the greatest. The order is

$3.5*10^{-2}, 3.5*10^3, 5.3*10^3$
