Step-by-step explanation:

Answer:

(1,12) ; (2,9) ; (3,6) ; (4,3) ; (5,0)

Step-by-step explanation:

You need to plug the x values into the equation.

Your equation: y=15-3x

Example:

Plug in 1

y=15-3

y=12

Plug in 2:

y=15-3(2)

y=15-6

y=9

Plug in 3:

y=15-3(3)

y=15-9

y=6

Plug in 4:

y=15-3(4)

y=15-12

y=3

Plug in 5:

y= 15-3(5)

y=15-15

y=0

Rachel's beginning balance one year ago was $800.

Compound interest is applicable when there will be a change in the principle amount after the given time period.

For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.

Given that,

The current balance is $836 which is the result of compound interest of 4.5 % annually.

The original amount was a priciple amount P on which interest was applied and the final amount $836 made.

Compound interest formula;

A = P[ 1 + RT/100]^T

Where A is the final amount and T is the time period.

Here,

A = 836 , R = 4.5% and T = 1 year.

So,

836 = P[1 + 4.5/100]^1

P = 836/1.045 = $800

Hence "Rachel's beginning balance one year ago was $800".

Answer:

y = 3x -2

Step-by-step explanation:

General equation of a line in the slope intercept form is

y = mx + b ,

where m is the slope and b is the y-intercept ( where intercepts the y-axis)

y = 3x + b ,

because is given slope is m = 3

For point (x = -2, y = -8) we have

-8 = 3 (-2) + b

-8 = -6 + b

-8 + 6 = b

-2 = b

The equation of the line that passes through the point (-2,-8) and has a slope of 3 is

y = 3x -2

The product of the given expression is -3ed + 3e^2 showing that they contain two terms and the product has a degree of 2.

Equations are expressions separated by an equal sign.

Given the following expression

(–d + e)(4e + d).

We are to take the product of both expressions.

Expand to have:

(–d + e)(4e + d) = -4ed - d^2 + 4e^2 + de

(–d + e)(4e + d) = -3ed + 3e^2

Hence, there are two terms in the solution and the product is degree 2.

A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.

The surface area formula for a cube is 6l²

A cube has the following features:

The area of a face of a cube is:

Area = l²

Where l represents the side length

The surface area formula for a cube is then calculated using:

Surface area = 6 * Area of a face

So, we have:

Surface area = 6 * l²

Surface area = 6l²

Hence, the surface area formula for a cube is 6l²

Answer:

✏The correct option is B Rs 73,333

Per capita income is the sum of all income sources, divided by the total number of people. Here the gross income of the family is = Rs (1,80,000+ 40,000) = Rs 2,20,000, the pocket money won't be added as it is an expense for the family. Then the per capita income of the family= Gross income / 3 (as the family has three members) = Rs 73,333.

Step-by-step explanation:

Percent is a relative quantity. Earning of our family is more than our friend's family (on monthly basis), by  11.11% approximately. (compared to friend's family's monthly income)

Percent is a relative quantity, as it is the measure of one quantity per 100 units of other quantity.

We want to know how much percent of 'b' is 'a'.

Then, it is calculated as:

[tex]\dfrac{a}{b} \times 100[/tex]

(in percentage)

For this case, we're specified that:

For our family:

Total monthly income = ₹(40000 + 35000 + 25000) = ₹100,000

For friend's family:

Total monthly income = ₹(45000 + 30000 + 15000) = ₹90,000

Thus, we see that friend's family's monthly is monthly ₹10,000 less than our family's monthly income.

We need to find how much percent this ₹10,000 is of their family because we need to find by how much percent our family's income is more than the friend's family's monthly income (so comparison is with respect to the monthly income of friend's family).

Let P be the percent the ₹10,000 is of the amount ₹90,000

Then, we get:

[tex]P = \dfrac{10000}{90000} \times 100 = \dfrac{100}{9} \approx 11.11 \%[/tex]

Thus, earning of our family is more than our friend's family (on monthly basis), by  11.11% approximately. (compared to friend's family's monthly income)

The transformation that is implemented is clockwise rotation by 270° about the origin and dilation by a scale factor of 1/2 .

The process of transformation an existing graph or equation into a new graph is known as graph transformation . The alteration of algebraic equations is a typical form of algebraic challenge.

A transformation modifies the graph of a parent function. Dilations, reflections, and translations are the three distinct types of transformation . The y-values of a function can be changed vertically, or the x-values can be changed horizontally (affects the x-values).

In the given figure we can see that the length of the side BC of the figure is 4 units, where as the length of the corresponding side in the image is

2 units . Hence the image is dilated buy a scale factor of 1/2 .

And from the transformation  figure it is clear that the image has rotated either 270° clockwise or 90 ° counterclockwise.
