Answer:

second answer: y = 5x + 120; $180

Step-by-step explanation:

he starts with $120.

so, whatever else he does per month, there will always be the $120 starting amount to be added.

so, the third and the fourth answers are out.

then think : $5 every month.

that is how much after 2 months ? 2×5 = $10.

how much after 3 months ? 3×5 = $15.

so it has to be an equation that contains 5x (5 times the number of months).

combining both thoughts :

y = 5x + 120

now let's use x = 12 (for 12 months = 1 year).

5×12 + 120 = 60 + 120 = $180.

yes, it is that simple. no hidden "hocus pocus" is needed. just common sense.

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Answer:

264 Adults & 217 Children

Step-by-step explanation:

children = c

adults = a

a + c = 481...(Equation 1)

1.25c + 2.25a = 865.25...(Equation 2)

Equation 1 can also be written as,

a = 481 - c

Now we can substitute the value of 'a' in Equation 2

1.25c + 2.25 (481 - c) = 865.25

1.25 c + 1082.25 - 2.25c = 865.25

-c = 865.25 - 1082.25

-c = -217

c = 217

Now, we can substitute the value of 'c' in Equation 1

a + c = 481

a + 217 = 481

a = 481 - 217

a = 264

To find f(f^(-1)(9)), we need to first find f^(-1)(9), the inverse of f(9).

Given that f(4) = 9, we know that f^(-1)(9) is equal to 4.

Therefore, f(f^(-1)(9)) is equivalent to f(4).

Given that f(4) = 9 according to the problem statement, we can conclude that f(f^(-1)(9)) = 9.

1) Last year, Maria spent $2093.75. Here's the equation to find that answer:

(a ÷ b) × c

(15,000 ÷ 24) × 3.35

2) Same equation. (15,000 ÷ 32) × 3.35. The answer of this equation is 1570.3125, but that rounds to $1570.31.

3) This part represents a simple difference/subtraction problem. Since she spent $2093.75 last year, and will spend $1570.31 with a new car, she will save 523.44.

4) Using percent of change, the percent decrease Maria will realize in one year is 33.333%, or \(\frac{1}{3}\).
