Let f(x) = 2x - 3. If f(x) = 15, what is x?

To find the value of input value 'x' of the function substitute the value of output value f(x) in the given function.

    If f(x) = 2x - 3 and we have to find the values of 'x' for f(x) = 15

    Substitute the value of f(x) in the given function,

15 = 2x - 3

2x = 15 + 3

2x = 18

x = 9

  • If g(x) = 3x + 2
  • For g(x) = 11

11 = 3x + 2

3x = 11 - 2

3x = 9

x = 3

  • If w(x) = 3x - 7
  • For w(x) = 14

114 = 3x - 7

3x = 21

x = 7

  • If h(x) = -2x - 5
  • For h(x) = -25

-25 = -2x - 5

25 = 2x + 5

2x = 20

x = 10

When comparing answers on a group assignment, Jenny and Jeremy found that their answers did not match. Part 1: Who do you believ
vitfil [10]
PART 1:

Jeremy gives the correct answer. 

The value of 0.41 [with a bar over the digit 4 and 1] shows that the digit 4 and 1 are reoccurring = 0.414141414141414141....

Jenny's assumption of 41/100 will give a decimal equivalency of 0.41 [without a bar over digit 4 and 1]. This value is not a reoccurring decimal value. 

PART 2:

The long division method is shown in the picture below

PART 3:

As mentioned in PART 1, the result of converting 41/100 into a decimal is 0.41 [non-reoccuring decimal] while converting 41/99 into a decimal is 0.41414141... [re-occuring decimal]. The conjecture in PART 1 is correct

If the FDIC has an insurance fund of $67. 8 billion and must use 7. 6% of it to cover several failed banks, approximately how mu
Black_prince [1.1K]

The remaining money will be $62. 65 billion

<h3>What will be the remaining fund in FDIC?</h3>

Given amount =$67. 8 billion

Amount used to cover several failed banks = 7.6% of the total amount

So the amount used to cover several failed banks=  \dfrac{67.8\times 7.6}{100}

Amount = 5.1528

So the remaining amount = 67.8-5.15=62.65

Thus the remaining money will be $62. 65 billion

Simora [160]

Answer:

the area is 10 feet by 10 feet, 100 feet²

subtract the area of the circle from this.

you get it by A = r² * pi

so 5² * 3.14159...

=78.5398163397

100-78.5398163397

is roughly 21.46 square feet

matrenka [14]

Answer:

x ≈ 63.27

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan49° = \frac{opposite}{adjacent} = \frac{EF}{DE} = \frac{x}{55} ( multiply both sides by 55 )

55 × tan49° = x , then

x ≈ 63.27 ( to the nearest hundredth )
