Answer:

C. x - 4

Step-by-step explanation:

f(x) = 3x - 6

g(x) = 2x - 2

To find f(x) - g(x), we'll substitute these 2 functions with their definitions above.

f(x) - g(x)

Putting in f(x):

(3x-6) - g(x)

Putting in g(x):

(3x-6) - (2x-2)

Expanding the parenthesis, we see that - (2x-2) becomes -2x + 2

The positive, 2x, becomes negative. The negative, -2, becomes positive.

3x - 6 - 2x + 2

Now just moving the x-terms together:

3x - 2x - 6 + 2

Since 3x-2x = x

x - 6 + 2

Since -6 + 2 = -4

x - 4

Answer: x - 4

If there are twice as many bicycles as scooters and there are 945 vehicles in total. How many bicycles and scooters are there in
alexandr402 [8]

Answer:

Bicycles = 315

Scooters = 630, basic mathematics. The most effective method for these questions is substitution. But I might have intermingled them so double check

Pls help with stats
aleksklad [387]

Answers:

  1. Exactly 25%
  2. median = 450
  3. Not enough info (see below)
  4. IQR = 24
  5. IQR = 192

=========================================================

Explanations:

  1. By definition, the quartiles split the data into four equal parts. The first quartile (Q1) will have 25% of the data below it.
  2. The second quartile is the exact same value as the median. This is because the median splits the data into two equal halves, i.e. is at the midpoint.
  3. There's not enough info. We can determine that 25% of the company makes more than $60,000, but we don't know how many people total work at the company. This info is missing.
  4. Subtract the third and first quartiles (Q3 and Q1) to get the interquartile range (IQR). So IQR = Q3 - Q1 = 45-21 = 24
  5. Same idea as the previous problem. IQR = Q3 - Q1 = 316.5 - 124.5 = 192

Reika [66]

Answer:

16. x = 3.0822, -3.0822

17. x = 1.6432, -1.6432

18. x = 1, -1

Step-by-step explanation:

16. log5[(4x²+2)/8] = 1

(4x²+2)/8 = 5¹

4x² + 2 = 40

4x² = 38

x² = 38/4

x² = 19/2

x = +/- sqrt(19/2)

x = 3.0822, -3.0822

17. log7[(2x²-4)(5)] = 1

10x² - 20 = 7¹

10x² = 27

x² = 2.7

x = +/- sqrt(2.7)

x = 1.6432, -1.6432

18. log5[(2x²+8)/2] = 1

x² + 4 = 5¹

x² = 1

x = +/-1
