If a function is defined by the equation y=12x−32, which equation defines the inverse of this function?

A. y=2x+3
B. y=2x+32
C. y=2x−3
D. y=2x−32

Answers

Answer:

A. Y=2x+3

Step-by-step explanation:

because im right

If a function is defined by the equation y = 2x−32, the equation that defines the inverse of this function would be: B. y=2x+32

How to determine the inverse

To determine the inverse of the function, we would first replace x with y in the function:

y = 2x - 32

x = 2y - 32

x + 32 = 2y

Divide both sides by 2

x/2 + 32/2 = y

f−1(x) = x/2 + 32/2

The common facot between the denominatoes of the values is 2. So, when expanded, we have;

(x + 32)/2

So, the closest option that represents the inverse is B. y=2x+32.

Elaine is in London for one day only. She only has time to see two shows of the three shows she likes. The shows are Hamilton, Aladdin and Thriller. She makes her choice of the two shows at random. What is the probability that she sees Aladdin and Thriller?

Answers

Answer:

[tex]\frac 13[/tex]

Step-by-step explanation:

All three shows she likes are Hamilton, Aladdin, and Thriller.

But she can watch only two shows among the three shown.

The possible combination of the shows she can watch are

(Hamilton and Aladdin), (Aladdin and Thriller) and (Hamilton and Thriller).

So, the total number of possible events (available options)= 3.

As we have to determine the probability of watching Aladdin and Thriller, so here Aladdin and Thriller is the favorable event.

So, the number of favorable event=1

Now,

[tex]\text{Probability}=\frac{\text{Total number of possible events}}{\text{Total number of favorable events}}[/tex]

[tex]=\frac{1}{3}[/tex]

Hence, the probability that she sees Aladdin and Thriller is [tex]\frac 1 3[/tex].

How can you know if this equation is true? 12+38=410=25 1 2 + 3 8 = 4 10 = 2 5 CLEAR CHECK Because 1+3=4 1 + 3 = 4 and 2+8=10 2 + 8 = 10 , this equation must be true. Because 25<12 2 5 < 1 2 , this equation can not be true. This equation must be true, because when you add fractions the sum is always less than 12 1 2 . Because 38<12 3 8 < 1 2 , this equation must be true.

Given:

The equation is

To find:

Whether the given equation is true or not.

Solution:

In addition of two fractions, we can not add numerator and denominator separately. First we need a common denominator, then we add numerators.

We have,

[tex]\dfrac{1}{2}+\dfrac{3}{8}[/tex]

Taking LCM, we get

[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{1\times 4+3}{8}[/tex]

[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{4+3}{8}[/tex]

[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{7}{8}\neq \dfrac{4}{10}[/tex]

So, the given equation is not true.

Therefore, the correct option is B.

Answer:

Factored form: (x+4)(x+5) = 0

x = -5 or -4

Step-by-step explanation:

To factor x^2 + 9x + 20, we need to find 2 numbers that multiply to 20 and add up to 9.

The reason for that is because when you multiply (x+a)(x+b) using FOIL, you will get x^2 + ax + bx + ab.

Anyway, 4 and 5 would satisfy this, because 4+5 = 9 and 4*5 = 20. We can then factor the equation to (x+4)(x+5).

To solve (x+4)(x+5) = 0, we need to make either x+4 = 0 or x+5 = 0. That means x can be either -5 or -4.

Answers

Answer:

Around 10.6 years

Step-by-step explanation:

5.75% of 4500 is 258.75

then we will need to subtract the current amount from the final amount.

10000-4500=5500

next

5500/258.75=21.256

finally

21.256/2=10.628

The person leaves the money in the bank until it reaches 10000 dollars.

We have given that

A person invests 4500 dollars in a bank.

The bank pays 5.75% interest compounded semi-annually.

Therefore we have,

What is compounded semi-annually?

The principal of a loan or investment at the beginning of the compounding period, in this case, every six months, includes the total interest from each previous period

5.75% of 4500 is 258.75

[tex]=\frac{5.75}{100}\times 4500\\ =258.75[/tex]

Then we will need to subtract the current amount from the final amount.

10000-4500=5500

5500/258.75=21.256
