Answer: To find the percentage of the down payment to the purchase price, just multiply the down payment by 100 and divide the result by the   purchase

i.e 15,000 x 100/ 150,000= 10%

Also for the second part, multiply the down payment by 100 and divide by the purchase price

i.e 67,500 x 100 / 150,000= 45%

The statement that provides the correct analysis of Maggie's claim is the following option;

Maggie's claim is incorrect because when g(x) is substituted into every occurrence of x in f(x), f(g(x)) = x - 8; therefore, g(x) is not the inverse of f(x)

Question: The functions in the question are presented as follows;

[tex]g(x) = \dfrac{x}{3} - 4[/tex]

f(x) = 3·x + 4

Required:

The statement that provides a correct analysis of Maggie's claim

Solution:

The inverse of f(x) is found as follows;

y = 3·x + 4

[tex]x = \dfrac{y - 4}{3}[/tex]

Therefore;

[tex]f^{-1}(x) = \dfrac{x - 4}{3}[/tex]

The inverse of a function above was found by making x the subject of the

function f(x), therefore, when the inverse f⁻¹(x) is substituted into all

occurrence of x in f(x), we get x

However, when g(x) is substituted into every occurrence of x in g(x), we get;

[tex]f \left (g(x) \right) = 3 \times \left (\dfrac{x}{3} - 4 \right)+ 4 = x - 8 \neq x[/tex]

Therefore, the given function g(x) is not the inverse of the function f(x) and the correct option is as follows;

Maggie's claim is incorrect because when g(x) is substituted into every occurrence of x in f(x), f(g(x)) = x - 8; therefore, g(x) is not the inverse of f(x)

Hi I had the same question on my test and the answer is  c or b

The solution is, The initial payment will be  $437.50.

Here, we have,

given that, Steven has obtained a $105,000 5/1 30-year ARM at 5%. During the first 3 years, he has an option of paying interest only.

so, we get,

Steven has obtained a $105,000, 5/1 30-year ARM at 5%.

During the first 3 years, he has an option of paying interest only.

So, it is simple interest.

Simple interest is given as :

I = p*r*t/100

here, p = 105000

r = 5%

t = 30

Putting values in formula:

= $157500

As this is interest for 30 years or 360 months.

So, for initial interest we will divide the interest with 360.

$157500/360

≈$437.50

Therefore, the initial payment will be $437.50

Answer:

56 and 16

Step-by-step explanation:

Set up equations!

x+y=72

x-y=40

You can solve for this by crossing out y as it becomes eliminated. You are left with 2x= 112. Then solve, so x= 56. Take 56 for x and plug it into one of the equations and solve for y. 56-y=40-----> y= 16. The numbers are 16 and 56.

Using a system of equations, it is found that the numbers are 16 and 56.

Their sum is of 72, thus:

[tex]x + y = 72 \rightarrow y = 72 - x[/tex]

Their difference is of 40, thus:

[tex]x - y = 40[/tex]

Since [tex]y = 72 - x[/tex]

[tex]x - (72 - x) = 40[/tex]

[tex]2x = 112[/tex]

[tex]x = \frac{112}{2}[/tex]

[tex]x = 56[/tex]

Then:

[tex]y = 72 - x = 72 - 56 = 16[/tex]

The numbers are 16 and 56.

Answer:

Step-by-step explanation:

At a Baseball Match.

35% of spectators are New York Yankees fan

The rest are Boston Red Sox fan = 100 - 35% = 65%

30% of fans in both teams are females.

30% of 35% of spectators are New York Yankees fan = 0.105 females

30% of 65% of spectators are Boston Red Sox fan = 0.195 females

The number of males in New York Yankees fan = 1 - 0.105 females

= 0.895 males

The number of males in Boston Red Sox fan = 1 - 0.195 females

= 0.805 males

[tex]T(x)=84-2x[/tex]

Step-by-step explanation:

Linear Modeling

The initial temperature outside is 84 degrees.

We are told the temperature drops 2 degrees every hour.

Let's call x to the number of hours elapsed. After x hours, the temperature would have dropped by 2x degrees, since it's a rate of 2 degrees per hour.

That drop is subtracted from the initial temperature to produce the linear model as follows:

[tex]\mathbf{T(x)=84-2x}[/tex]

This is the linear equation that represents the described situation.

[tex]\left(-t^4-5t^3-10t^2\right)+\left(9t^3+3t^2-1\right)=-t^4+4t^3-7t^2-1[/tex]

Step-by-step explanation:

Given the expression

[tex]\left(-t^4\:-5t^3\:-10t^2\:\right)+\left(9t^3\:+3t^2\:-1\right)[/tex]

Remove parentheses:  (a)=a

[tex]=-t^4-5t^3-10t^2+9t^3+3t^2-1[/tex]

Group like terms

[tex]=-t^4-5t^3+9t^3-10t^2+3t^2-1[/tex]

Add similar elements        

[tex]=-t^4-5t^3+9t^3-7t^2-1[/tex]         ∵ [tex]-10t^2+3t^2=-7t^2[/tex]

Add similar elements        

[tex]=-t^4+4t^3-7t^2-1[/tex]                  ∵  [tex]-5t^3+9t^3=4t^3[/tex]

Thus, the equivalent expression in simplified form:

[tex]\left(-t^4-5t^3-10t^2\right)+\left(9t^3+3t^2-1\right)=-t^4+4t^3-7t^2-1[/tex]
