Explanation:

Part A.

1. You have provided an estimate of 600 minutes per month.

__

2. The cheapest plan is likely to be Plan 6 (Public Mobile), as it has no per-minute charge.

__

Part B.

1. Table 2.

See the first attachment for Table 2. For the chosen plan, there is no per-minute charge, so the monthly charge is the same for all numbers of minutes.

__

2. Rate of Change and Slope (m)

a) Adding a minute adds $0 to the cost

b) The rate of change (m) is 0/1 = 0 (dollars per minute)

__

3. Initial value (b)

a) The plan costs $24.00 when no minutes are used.

b) The initial value (b) is 24.

__

4. Equation of the line

a) Filling the found values of m and b into the equation of the line, we have ...

  y = mx + b

  y = 0x + 24

  y = 24 . . . . . . simplified

__

Part C.

Table 3 can be found in the second attachment.

The b in each case is the value from the Monthly Cost column of Table 1.

The m in each case is the value from the Cost per minute column of Table 1.

The equation is found by copying the values of m and b into y = mx + b.

The number in the last column is found by multiplying the minutes (x) by m, then adding b. For example, your cost for Plan 5 (BELL) is ...

  y = 0.10x + 10

  y = (0.10)(600) +10 = 60 +10 = 70

Answer:

Step-by-step explanation:

Based on similar triangle;

14/49 = x+5/9x+1

Cross multiply

49(x+5) = 14(9x+1)

49x + 245 = 126x + 14

49x - 126x = 14 - 245

-77x = -231

x = -231/-77

x = 3

Hence the value of x is 3

Answer:

p=-17/9 or p=-1.8889

Step-by-step explanation:

-9p-17=10

add 17 to each side

-9p-17+17=10+17

-9p=17

divide both sides by -9

-9p/-9=17/-9

p=-17/9

or p=-1.8889

Solution of equation - 9p - 17 = 10 is p = -3.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

For example, 3x – 5 = 16 is an equation.

Given equation

- 9p - 17 = 10

Add 17 to both sides

- 9p - 17 + 17 = 10 + 17

Adding the numbers

- 9p = 10 + 17

Adding the numbers

- 9p = 27

Divide both sides by - 9

-9p/ - 9 = 27/ - 9

Cancel terms that are in both the numerator and denominator

p = 27/ - 9

Divide the numbers

p = -3

Hence, p = -3 is the solution for equation - 9p - 17 = 10

Step-by-step explanation:

Answer: 1

Step-by-step explanation:

Given:

Principal value = 4580

Rate of interest = 6% apr compounded weekly

To find:

The total amount after 2 years.

Solution:

The formula for amount is

[tex]A=P\left(1+\dfrac{r}{100n}\right)^{nt}[/tex]

Where, P is principal, r is rate of interest, n is number of times interest compounded in an year and t is number of years.

1 year = 52 week

n=52

Putting P=4580, r=6, n=52, t=2 in the above formula, we get

[tex]A=4580\left(1+\dfrac{6}{100(52)}\right)^{52\times 2}[/tex]

[tex]A=4580\left(1+\dfrac{6}{5200}\right)^{104}[/tex]

[tex]A=4580\left(1+\dfrac{3}{2600}\right)^{104}[/tex]

[tex]A=4580\left(\dfrac{2603}{2600}\right)^{104}[/tex]

On further simplification, we get

[tex]A=4580(1.1274188)[/tex]

[tex]A=5163.5781[/tex]

[tex]A\approx 5163.58[/tex]

Therefore, the ending balance after 2 years is 5163.58.

A. all of the answers are correct when you plug in these values

The solution of the linear equations will be (1, 1, 2). Then the correct option is A.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

The equations are given below.

2x - y - z = -1        ...1

3x + y - z = 2       ...2

x + y - 5z = -8      ...3

Add equations 1 and 2, then we have

5x - 2z = 1       ...4

Add equations 1 and 3, then we have

3x - 6z = -9     ...5

From equations 4 and 5, then we have

15x - 3x = 12

12x = 12

x = 1

From equation 4, then we have

5(1) - 2z = 1

2z = 4

z = 2

From equation 1, then we have

Answer:

7.632

Step-by-step explanation:

When solving this equation, you need to substitute the number equal to a where the a is in the equation, along with the b and c. So since a=0.32, then I would put that where the a is in 3ab+c. Same goes with the other letters.

a = 0.32

b = 0.45

c = 7.2

3ab+c

3(0.32)(0.45)+7.2 *Multiply the 3 to 0.32

0.96(0.45)+7.2 *Multiply the 0.96 to 0.45

0.432+7.2 *Add
