Answer: The scale factor was used in the dilation = -4

Step-by-step explanation:

The scale factor of dilation is the ratio of the side-length in the image to the corresponding side length in the pre-image.

From the given picture, the length of side SR in pre-image = 3cm

The length of corresponding side S'R' in image = 12 cm

Then , the scale factor of dilation will be :-

$k=\dfrac{12}{3}=4$

Since , the enlargement appearing on the other side , then the scale factor becomes negative.

Hence, the scale factor of this dilation =-4.

Choose the correct solution and graph inequality q + 1/3 > 1/2

kherson [118]

Answer:

first choice

Step-by-step explanation:

make 1/3 and 1/2 a common denominator, which is 6.

1x2

- = 2

3x 2 6

1 x 3

- = 3

2 x 3 6

now u have 2/6, and 3/6

u subtract 2/6 by 3/6 since ur finding a solution to an inequality. remember to do the opposite sign.

2/6-2/6 = 0 (u cancel that out)

3/6 - 2/6 = 1/6

now u have

q>1/6

since there's no 1/6 the first choice is the most accurate

I need the answer please. Because I think i got mine wrong

Gekata [30.6K]

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

• $a^{-m}$ ⇔ $\frac{1}{a^{m} }$

• $a^{0}$ = 1

• $a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

Given

(a)

$8^{-2}$ = $\frac{1}{8^{2} }$

(b)

$\frac{1}{3^{-3} }$ = 3³

(c)

$6^{-12}$ × $6^{8}$ × $6^{0}$

= $6^{(-12+8)}$ × 1

= $6^{-4}$

= $\frac{1}{6^{4} }$
