Step-by-step explanation:

The function that models the value of the phone x years after its purchase is y = 1200(0.867)^x

The standard exponential equation is given as:

y = ab^x

From the given question

a = 1200

b = 1 - 0.133

x is the time

Substitute to have:

y = 1200(1-0.133)^x
y = 1200(0.867)^x

Hence the function that models the value of the phone x years after its purchase is y = 1200(0.867)^x

Answer:

8) y=10

9) z=4

Step-by-step explanation:

substitute and solve

Answer:

Step-by-step explanation:

1. y - 4 = 1/2(x - 2)

  y - 4 = 1/2x - 1

  y = 1/2x + 3

2. y + 1 = -3/4(x + 8)

   y + 1 = -3/4x - 6

  y = -3/4x - 7

To solve this problem, you read the problem backwards and to the opposite of that function.

Thus the number that is thought of is 6

= 3/4 ÷ 2

= 3/(4×2)

= 3/8 (final answer)

Answer:

17/12 or 1 5/12

Step-by-step explanation:

Fraction halfway between refers to the mean of the two fractions.

Answer:

$0.99

Step-by-step explanation:

A thin blue marker = $0.80

A bright yellow highlighter = $0.74

First, find the total cost of these two products. Add the costs together:

0.80 + 0.74 = 1.54

Anna has $2.53 in all. Subtract 1.54 from 2.53:

2.53 - 1.54 = $0.99

Anna will have $0.99 left.

Answer: 16

Step-by-step explanation:

Standard deviation is 2

Margin error for the problem is 1

Probability 95%, that means thet the siginficance level α is 1 – p

α = 1 – 0.95 = 0.05

margin of error (ME) can be defined as follows

ME = Z(α/2) * standard deviation/ √n

Where n is the sample size

Z(0.05/2) = Z(0.025)

Using a z table Z = 1.96

Now, replacing in the equation and find n

1 = 1.96 * 2/ √n

1 = 3.92 / √n

√n = 3.92

n = 3.92^2

n = 15.36 = 16

Answer:

The probability is 0.1473

Step-by-step explanation:

Given;

total number of students, n = 50

number at hospital, h = 14

number at pet shelter, p = 15

number at tutoring, t = 8

number at library, L = 13

If three students are chosen at random without replacement, the number of students that will be selected to work in other location is given by;

50 - 13 = 37 students

The probability that the first student volunteers at the library and the other two do not is given by;

P(13 students at library) x P(2 out of the 37 students did not)

[tex]= (\frac{13}{50})(\frac{37}{49})(\frac{36}{48} )\\\\ = 0.1473[/tex]

A quadratic equation is written in the form of ax²+bx+c. The factors of the given tile configuration are (x-4).

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.

It is written in the form of ax²+bx+c.

In order to write the algebra tile configuration of the given problem, we need to convert sentences one by one. Therefore, the description can be converted as,

Now, adding all the tiles configuration together we will get,

[tex]x^2 - 8x + 16[/tex]

As we got the quadratic equation now, the roots of the quadratic equation can be written as,

[tex]x^2 - 8x + 16 = 0\\\\x^2-4x-4x+16=0\\\\x(x-4)-4(x-4)=0\\\\(x-4)(x-4)=0\\\\(x-4^2)=0[/tex]

Thus, the factors of the given tile configuration are (x-4).

Answer:

a)  Down payment = $1039.50

b) Amount financed = $4158

c) Monthly payment =  $121.73

d) Total finance charge = $5112.66

Step-by-step explanation:

Area of rectangle = width × length

⇒ area of room = 15 × 22 = 330 ft²

Given:

⇒ Total cost of flooring = area × cost = 330 × 15.75 = $5197.50

a)  Down payment = 20% of $5197.50

                              = 0.2 × 5197.50

                              = $1039.50

b) Amount financed = total cost - down payment

                                 = 5197.50 - 1039.50

                                 = $4158

c) Monthly payment = [tex]\dfrac{4158 \cdot \frac{0.12}{12}(1+\frac{0.12}{12})^{42}}{(1+\frac{0.12}{12})^{42}-1}[/tex]=  $121.73

d) Total finance charge = monthly payment × number of months

                                       = 121.73 × 42

                                       = $5112.66

Answer:

Step-by-step explanation:

The infinite solution is when the equation equals something like this:

10 = 10

2 = 2

586 = 586

One solution is when the answer to an equation is something like this

x = 4

x = 17

y = 657

y = 7

No solution is when the equation 'doesn't make sense' or something:

4 = 10

17 = 64

6 = 9
