Answer:

  • 17. No
  • 18. Yes
  • 19. Yes

Step-by-step explanation:

There are several ways you can determine the equivalence of two ratios:

  1. Reduce each one to lowest terms. Equivalent ratios will have identical lowest terms.
  2. Perform the division indicated by the ratio. Equivalent ratios will have identical quotients.
  3. Multiply each ratio by the product of the denominators. Equivalent ratios will have identical products.

For these problems, these methods look like ...

17. In lowest terms: 8/5 and 6/5. (not equivalent)

Performing the division: 1.6 and 1.2. (not equivalent)

Multiplying each by 100: 160 and 120. (not equivalent)

___

18. In lowest terms: 1/20 and 1/20. (equivalent)

Performing the division: 0.05 and 0.05. (equivalent)

Multiplying each by 1000: 50 and 50. (equivalent)

___

19. In lowest terms: 1/4 and 1/4. (equivalent)

Performing the division: 0.25 and 0.25. (equivalent)

Multiplying each by 249.6: 62.4 and 62.4. (equivalent)

Need Help With Math. One Question
alina1380 [7]

Answer: 2 < x < 16

The triangle inequality theorem says that if we have a triangle with sides a,b,c then

b-a < c < b+a

with b being longer than 'a'

In this case, a = 7 and b = 9 and c = x

so we have

b-a < c < b+a

9-7 < c < 9+7 .... replace a with 7, replace b with 9

2 < c < 16

2 < x < 16 .... replace c with x

So x can be any number between 2 and 16. The value of x cannot be equal to 2. Also, x cannot be equal to 16 either.

Answer: \Large\boxed{f(-9)=-189}

Step-by-step explanation:

f(x) = -3x² - 6x

<u>Requirements of the question</u>

Find the value of f(-9)

<u>Substitute values into the given function</u>

f(x) = -3x² - 6x

f(9) = -3 (-9)² - 6 (-9)

<u>Simplify the exponent</u>

f(9) = -3 (81) - 6 (-9)

<u>Simplify by multiplication</u>

f(-9) = (-243) - (-54)

<u>Simplify by subtraction</u>

\Large\boxed{f(-9)=-189}

Hope this helps!! :)
