Answer:

x = -13

Step-by-step explanation:

Isolate the variable (x)

9 - 2x = 35

Subtract 9 from both sides

This action cancels out the 9 on the side of the variable

- 2x = 35 - 9

- 2x = 26

Divide by -2 on both sides

x = 26 ÷ -2

x = -13

Anyone know these two questions??
gogolik [260]

1):  Answer  =====>  Letter Choice, (B),  The rate in which you walked home, The slope is the same, as the Rate of Change, In Distance Divided by the Change in Time  =====>    d    =     4   -1/15t(4) / 1/15t

 

2):   The Equation:  d     =       -1/15t     +     4

The more the Number of Minutes:  Larger the Negative Quantity;  ====>   -1/15t

The Larger the Negative Quantity in Equation:  D value is Smaller:

Therefore your Answer ===>  The Distance from home (d), Decreased with Minute Walked (t)  ====>  So, Letter Choice,  (C)



2):   Towards your home, The slope is Negative, and the Distance (y - value), Decreases, as the Time  (x- Values),  Increases. Notice the Slope is Negative, Because, you are getting closer to home.






Hope that helps!!!!                                           : )

Which choice most effectively combines the
Thepotemich [5.8K]

The Choice D is the best answer by the passage because it most clearly and concisely combines the sentences using the correct punctuation. This choice eliminates unnecessary words, and the commas are placed correctly between the clauses.

According to the statement

we have to find that the out of given options which is correct for replace the words in the passage.

So, For this purpose, we know that the

In the passage ,

Choice A is incorrect because the phrase “the result being that it” is wordy and could be replaced with the single word “which.” Choice B is incorrect because the words “algal blooms cause oxygen depletion” need not be repeated. Choice C is incorrect because there is unnecessary repetition of the words “oxygen depletion” and “algal blooms.”

So, The Choice D is the best answer by the passage because it most clearly and concisely combines the sentences using the correct punctuation. This choice eliminates unnecessary words, and the commas are placed correctly between the clauses.

Evaluate each trigonometric equation for θ.
liberstina [14]

Answer:

sinФ = 8/17

cosФ = 15/17

tan Ф = 8/15

csc Ф = 17/8

sec Ф = 17/15

cot Ф = 15/8

Step-by-step explanation:

Let us revise the trigonometry functions

  • Sin(x) = opposite/hypotenuse
  • Cos(x) = adjacent/hypoteouse
  • Tan(x) = opposite/adjacent
  • Csc(x) = hypotenuse/opposit
  • Sec(x) = hypotenues/adjacent
  • Cot(x) = adjacent/opposite

In the given figure

The opposite side to angle Ф = 8

The adjacent side to angle Ф = 15

Find the hypotenuse using Pythagoras' theorem

Hypotenuse = \sqrt{8^{2}+15^{2}  }

Hypotenuse = \sqrt{64+225}

Hypotenuse = \sqrt{289}

Hypotenuse = 17

Let us use the rules above to find the trigonometry functions

sinФ = 8/17

cosФ = 15/17

tan Ф = 8/15

csc Ф = 17/8

sec Ф = 17/15

cot Ф = 15/8
