S(x) = x - 7; t(x) = 4x² - x + 3

(t · s)(x) = (4x² - x + 3)(x - 7) = (4x²)(x) + (4x²)(-7) - (x)(x) - (x)(-7) + (3)(x) + (3)(-7)

= 4x³ - 28x² - x² + 7x + 3x - 21 = 4x³ - 29x² + 10x - 21

3.) 2 times a number = 2x

4.) 2 increased by a number = 2 + x

Step-by-step explanation:

Let's look for key words hidden in these sentences:

1.) The <u>quotient</u> of a number and 2 = The word quotient refers to division

2.) A number <u>decreased</u> by 2 = The word decreased refers to subtraction

3.) 2 <u>times</u> a number = the word times refers to multiplication

4.) 2 <u>increased</u> by a number = the word increased refers to addition

Solve the percent change . state if increase or decrease.
Dmitry [639]

Answer:

1.) 18 is decreasing by 83%

2.) 16 is decreasing by 12.5%

Step-by-step explanation:

Part ÷ Whole = Percent (decimal form)

1.) First, you subtract the smaller number from the larger number: 18 - 3 = 15. Then you find the percent of the part: 15 ÷ 18 = 0.833333333333. This can be rounded to 0.83. Multiply 0.83 by 100 to get the percentage: 0.83 • 100 = 83%. To check your answer, multiply 0.83 by 18. It checks out. 18 is being <em>decreased</em> by 83%.

2.) Subtract 14 from 16 to get 2. Then divide 2 by 16: 2 ÷ 16 = 0.125. Multiply that by 100: 0.125 • 100 = 12.5%. To check this, we multiply 0.125 • 16 = 2. It works. So, 16 is being <em>decreased</em> by 2%.

Hope this helps,
