If we notice, the decrease in payment after 3 and 5 months, it is a multiple of 150.

So, the equation that models balance b after m months is:

b = 1800 - 150m

Here, - 150 is the slope and it indicates the amount being decreased every month.

Answer:

balance (b) = 1800 - 150m, where "m" is the number of months.

Step-by-step explanation:

Zachary purchased a computer for 1800 on a payment plan.

After 3 months, his balance = 1350

Reduced amount = 1800 - 1350 = 450

So, 1 month payment = 450 ÷ 3 = 150

After 5 months, his balance = 1050

The reduced amount = 1800 - 1050 = 750

So, 1 month payment = 750 ÷ 5 = 150

Therefore, the rate of change = -150. It is negative because the amount getting reduced.

Therefore, the model is

balance (b) = 1800 - 150m, where "m" is the number of months.

Micheal has been awarded a pay rise of 4%.His salary is £ 24 492 <br> What was his apart before?
Nesterboy [21]
Because there was a pay rise, we can write the equation as x+0.04x = 24.492 and solve for x.

x+0.04x = 24.492
1.04x = 24.492
x=23.55

His original pay was £23.55

If f(x) = 3x – 4 and g(x) = x, find the value of f(3) – g(2).
Mamont248 [21]

Answer:

3

Step-by-step explanation:

f(3) = 3(3)-4

f(3)= 9-4

f(3) = 5

g(2) = (2)

g(2) = 2

f(3)-g(2) = ?

(5) - (2) = ?

(5) - (2) = 3

What is the volume of the cone? cone v = one-third b h startfraction 70 over 3 endfraction pi centimeters cubed startfraction 14
Bas_tet [7]

Using the assumed values, the volume of the cone is V = \frac {250}3\pi

<h3>How to determine the volume of the cone?</h3>

The volume of a cone is calculated using:

V = \frac 13\pi r^2h

The parameters are not given.

So, we use the following assumed values

Radius, r = 5

Height, h =10

Using the assumed values, we have:

V = \frac 13\pi * 5^2 * 10

Evaluate the product

V = \frac {250}3\pi

Hence, using the assumed values, the volume of the cone is V = \frac {250}3\pi

Kim purchased white vases, red vases, and flowers to create centerpieces for an event. The flowers cost a total of $336 and each
laiz [17]

Option A:

I and III only the answers.

Solution:

Let white vases be "w" and red vases be "r".

Cost of total flower = $336

Cost of each vase = $11

Total cost of the centerpieces

                = Cost of (white vases + red vases)  + Cost of flowers

                = 11(w + r) + 336

                = 11w + 11r + 336

Total cost of the centerpieces = 11w + 11r + 336 = 11(w + r) + 336

Therefore I and III only the answers.

Option A is the correct answer.
