Which scale factors produce a contraction under a dilation of the original image? Select each correct answer. ​−6​ ​−0.5​ 0.5 6
Step2247 [10]

A contraction would make the image smaller.


A negative number reflects the image and changes the size based on the number.


To make an image smaller the factor needs to be less than 1

so -0.5 and 0.5 would make the image smaller since 0.5 is less than 1.

9. Let p = Pico

3/4p = 18

10. Let h = height with pedestal and foundation

151 + h = 305

11. Let m = Meredith

19 = 3 + 2m

12. Let p = number of pizzas, $5 off is - 5 from regular price

3p - 5 = 21.75

13. Option C.

14. Option A. 

15. Let w = last week's miles

w = \frac{1}{2}(12) + 3

The word "half" tells you to use 1/2 in the equation. The phrase "three more than" tells you to use + 3. We multiply 1/2 by 12 (or divide 12 by 2; it's the same thing) because we are taking half of the miles Carmen ran "this week" as stated in the problem.

megan and kara play on a basketball team together. in the last game, Megan had 7 points less than 2 times as many points as Kara
insens350 [35]
You first have to start with an equation. Let's take what we know.
Megan has 31 points
To get 31, you have to enter in all the other information we know.
Megan's score is -7pts and 2 times Kara's points.
The equation would be: 31= 2k-7
Now you have to find the value of k. Start off by adding 7 to both sides of the equation because addition is the opposite operation of subtraction.
31=2k-7
+7 +7
38=2k

Now divide by 2 on both sides because division is the opposite operation of multiplication. You need to isolate* the variable(k)

38=2k
÷2 ÷2

19=k

The answer is that Kara scored 19 points. To make sure this is correct, substitute the variable,k, for 19. If the numbers are the same on both sides of the equals sign, the answer is correct.

*isolate also means to make something be alone/ by itself
