The function f is one-to-one. Find its inverse. F(x) = 2/x+5

Answer:

Your answer would be to Use the distributive property on each side of the equation.

Step-by-step explanation:

You would first expand the equation by using the distributive property on each side of the equation

[tex]2x + 9(x - 1) = 8(2x + 2) - 5\\2x + 9(x) 9(-1) = 8(2x) 8(2) - 5\\2x + 9x-9 = 16x+16 - 5[/tex]

Then you would combine like terms on both sides

[tex]2x+9x-9=11x-9\\16x+16-5=16x+11[/tex]

Now you solve for x

[tex]11x-9=16x+11[/tex]

You subtract 11x from both sides

[tex]11x-9=16x+11\\-11x=-11x[/tex]

Then you subtract 11 from both sides

[tex]-9=5x+11\\-11=-11[/tex]

Then you divide 5 on both sides

[tex]-20=5x[/tex]

[tex]\frac{-20}{5} =\frac{5x}{5}[/tex]

[tex]x=-4[/tex]

Answer:

2, 32

Step-by-step explanation:

The question is asking where X could be (what value it could have) to make it 15 away from W, making a line segment of that length if they were to be connected. This can be solved by individually adding and subtracting 15 to/from the value of W: 17. Adding 15 to 17 gives you 32, while subtracting gives you 2, and X could be either of these, so your answer is 2, 32. (It's common to order them in increasing order, but you shouldn't be marked off if you do it in reverse.)

Answer:

Depends on the value of x. If x = 3, the triangle has sides 18, 6, 16 which satisfies the triangle inequality, so 2x+12 is longest in this case. If x is very large, the triangle inequality is still satisfied, and 6x-2 is the longest side.

So on solving the provided question we can say we can plotting data by x = 0.83; y = 0.79; z = 0.83

Here, we have,

The most typical approach to display data using a chart is a graph that shows the relationship between two additional variables.

Diagrams created by hand or on a computer are also acceptable.

Move 2 units to the right after starting at the origin before going 3 units up.

The coordinates for the points 2, 3, should be shown on the coordinate plane. Clearly state your points.

The pink dot with the letter P thus stands for 2.3.

Before creating a line chart, you need first generate a number line for each value in your data collection.

Put an X (or dot) over each value of the data on the number line after that. For each instance when a value appears in a record, place an X over the corresponding number.

x = 0.83

y = 0.79

z = 0.83

xa = 0.85

ya = 0.85

za = 0.85

Answer:

[tex]\mathsf{\frac{4}{3} \:\times\frac{1}{2}\: =\: \frac{4}{3} \:\div\frac{2}{1}}[/tex]

Step-by-step explanation:

The mathematical operation of division is the opposite of multiplication. When you divide two fractions, you will have to take the reciprocal of the divisor, and multiply it with the dividend.  

In the given equation, [tex]\mathsf{\frac{4}{3} \:\times\frac{1}{2}\: =\: \frac{4}{3} \:\div\:?}[/tex], we can rewrite this as:  [tex]\mathsf{\frac{4}{3} \:\div\:?\:=\:\frac{4}{3} \:\times\frac{1}{2}}[/tex].

As previously mentioned, division is opposite of multiplication. Since the multiplicand  in the multiplication of two fractions is ½, then we can assume that the divisor (or the missing fraction) must be the reciprocal of ½, which is  [tex]\mathsf{\frac{2}{1}\:or\:2}[/tex].

Therefore, the missing fraction that completes the given mathematical statement is [tex]\mathsf{\frac{2}{1}\:or\:2}[/tex].  

[tex]\mathsf{\frac{4}{3} \:\times\frac{1}{2}\: =\: \frac{4}{3} \:\div\frac{2}{1}}[/tex]

Answer:

  (a) $254.08

  (b) $767.34

  (c) $12,449.36

Step-by-step explanation:

These questions are best answered by a financial calculator or app. Such are available for your phone or tablet. A spreadsheet also has built-in functions for making these calculations.

(a) FV = $40,000, i = 8% per year, n = 9 years (108 months), compounding 12 times per year. The monthly deposit needs to be $254.08.

__

(b) Payment = $254.08, n = 3 months, i = 8%/year, compounding 12 times per year. FV = $767.34.

__

(c) The sum of 108 payments of $254.08 is ...

  108 × $254.08 = $27,440.64

The interest earned is enough to bring the account value to $40,000, so is ...

  $40,000 -27,440.64 = $12,559.36

_____

Additional comment

The amount $254.08 is rounded down to the nearest cent, so the balance after 9 years will be $39,999.70, which is $0.30 short of $40,000. We used $40,000 as the final account balance, so overestimated the interest by $0.30.

There may be additional small changes in the values if you round interest to the nearest cent each month the way a financial institution would. It is hard to tell in these problems how accurate you're intended to be in your calculations.

Answer:

I don't know what to do with it

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol. See: Variable.

Answer:

These two equations are equivalent because the order of operations states you work from the right to the left and do the multiplication first. Because we do the multiplication first, we get the same answer as the other equation because the parentheses are also done first, meaning these equations both get the same answer.

Answer:

  b║c

  c║d

Step-by-step explanation:

For x=10, the marked angles are ...

  (7x-5)° = (70 -5)° = 65°

  (10x +15)° = (100 +15)° = 115°

  (12x -5)° = (120 -5)° = 115°

  (8x -25)° = (80 -25)° = 55°

We notice that the alternate interior angles between lines c and d are congruent, so those lines are parallel. The acute angle at line b is supplementary to the obtuse angle at lines c and d, so line b is parallel to those two lines, as well.

The angle at line e is not related to any of the other angles, so that line is not parallel to any of the others shown.

  b║c║d

The answer choices appear garbled, but any choice involving 'a' or 'e' must be eliminated.

The hearts and the diamonds.

Now so techincially its a 2/54 chance

So 2/54 chance of drawing a red card

Answer:

2/52

Step-by-step explanation:

52 cards in a deck as jokers are not used in professional card places   red = 1/2 of 52 = 26/52   drawing red 6   = 1/2 of  4/4   =  2/4      26/52  /  2/52  = 13 which proves 13 cards in each red and 2/52   red 6's in a full deck

4(x -4)(2x +1)

Step-by-step explanation:

8x² -16 -28x , rearrange it so the exponents will be going form highest to lowest

8x²-28x -16, factor 4

4(2x² -7x -4),

            to get 2x² we need to multiply an x and a 2x

            to get -4 we need to multyply 1 and -4 or -1 and 4 or 2 and -2 (can use       trial and error method here)

4(x -4)(2x +1)

Check

4(x-4)(2x+1) = (4x -16)(2x+1) = 8x² +4x -32x -16 = 8x²-28x -16
