Answer:

[tex]y = - \frac{5}{2} x + 4[/tex]

Step-by-step explanation:

The equation of a line in slope-intercept form is given by y= mx +c, where m is the slope and c is the y-intercept.

Start with the slope when forming the equation.

Given that the slope is [tex] - \frac{5}{2} [/tex], [tex]m = - \frac{5}{2} [/tex].

Substitute the value of m into the equation:

[tex]y = - \frac{5}{2} x + c[/tex]

The value of c can be found by substituting a pair of coordinates that the line passes through.

When x= -2, y= 9,

[tex]9 = - \frac{5}{2} ( - 2) + c[/tex]

9= 5 +c

c= 9 -5

c= 4

Thus, the equation of the line is [tex]\bf{y = - \frac{5}{2} x + 4}[/tex].

The principal plus interest which gives the amount in the account after each year are;

Simple interest is the product of the principal amount, the rate and the time of investment

The amount Brayden deposited in the savings account, P= $2,700

The interest on savings account, R = 0.3% simple interest

The simple interest formula is, I = P•R•T

The interest in the account after each year is therefore;

1st year = $2,700×0.3%×1 = $8.7

The interest in 2 years, I = 2×$8.7 = $17.4

3 years, I = $8.7 × 3 = $26.1

4 years, I = $8.7 × 4 = $34.8

5 years, I = $8.7 × 5 = $43.5

The amount in the account after each of the 5 years are therefore;

1st year, A = $2,700 + $8.7 = $2,708.7

2nd year, A = $2,700 + $17.4 = $2,717.4

3rd year, A = $2,700 + $26.1 = $2,726.1

4th year, A = $2,700 + $34.8 = $2,734.8

5th year, A = $2,700 + $43.5 = $2,743.5

The ratio is 3:5 .

The problem we are dealing with is related to the term ratio, where the ratio is characterized as the comparison of two quantities of the same units that shows how much of one amount is present within the other amount. Ratios can be classified into two sorts. One is part to part ratio and the other is part to whole ratio. The part-to-part ratio indicates how two distinct entities or groups are related. whereas, the part-to-whole proportion indicates the relationship between a particular group to an entirety.The situation we are given is that the player attempted 15 baskets in a game and out of  9 was the number of times he made the attempted baskets.We just need to find the ratio of the number of baskets made to the number of  baskets attempted,

Angle 2 is supplementary to Angle 3 Because it's given that to a supplementary to 3 lines A and B are parallel by the transverse line.

Two Angle whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

If ∠ 8 is supplementary to ∠ 9, then line x and y must be parallel lines wheres line s is the transverse line.

∠ 7 = ∠ 4.

Now, ∠ 7 = ∠ 2 and ∠ 4 = ∠ 9.

So, ∠ 2 = ∠ 3 {supplementary angles}

Angle 2 is supplementary to Angle 3 Because it's given that to a supplementary to 3 lines A and B are parallel by the transverse line.

Each x-value corresponds with only one y-value.

6.5 units to the left of the origin, and 2 units above the origin

A coordinate plane is a surface with two dimensions made up of two number lines. It is created when the origin, the point at which the X-axis and Y-axis cross, is reached. To locate points, one uses the numbers on a coordinate grid. A coordinate plane is useful for graphing points, lines, and many other things. It serves as a map and provides clear instructions for getting from one place to another

Coordinates are a pair of numbers that identify a specific point on a coordinate plane, often known as a grid of coordinates. The ordered pair (x, y), which corresponds to the X-coordinate and the Y-coordinate, is expressed in parenthesis and is used to identify a point in a coordinate plane. Depending on where the point is in relation to the different quadrants, these coordinates may be positive, zero, or negative.

The expression that models Tyrell's net proceeds algebraically is d-(1.03ns + 15)  .

In the question ,

it is given that ,

Tyrell bought n shares for s dollars

So the price Tyrell paid for shares = $ ns .

Tyrell also paid 3% commission ,

so the total cost price Tyrell paid for shares = price of share + commission

total cost price = ns + 3% of ns

= ns + 0.03ns        ....as 3% = 0.03

= 1.03ns         ...(i)

Tyrell sold the stocks for d dollars .

Tyrell also paid the flat fee of $15 .

So, the selling price for stocks = d-15 ......(ii)

The Tyrell's Net Proceeds can be calculated using the formula

Net Proceeds = Selling Price - Cost price

Substituting the values of selling price and cost price from (i) and (ii) ,

we get ,

Net Proceeds = (d-15)-(1.03ns)

= d-15-1.03ns

= d-(1.03ns + 15)

Therefore , the expression that models Tyrell's net proceeds algebraically is d-(1.03ns + 15)  .

The value of equation (x + y) will be 1.

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The equation are;

2y + 5x = 5   ... (i)

4y - x = 21    ... (ii)

Now, Solve both the equation and find the value of x and y as;

Multiply by 2 in equation (i) we get;

4y + 10x = 10

Subtract above equation by (ii);

4y + 10x - (4y - x) = 21 - 11

11x = 11

x = 1

And, 2y + 5x = 5

Substitute x = 1;

2y + 5x = 5

2y + 5 = 5

2y = 0

y = 0

The each expression of store A and store B represent the total cost charged by them based on the number of items bought. The mentioned expressions will be equated when assuming their total cost to be same. Thus, equating the the expressions.

20x - 8 = 5 (4x + 4)

Performing multiplication on Right Hand Side of the equation

20x - 8 = 20x + 20

Since 20x is present on both the sides, it will be cancelled. The remaining expression will be :

8 = 20, which is a false case as 8 is not equal to 20.

The differential equation for the amount of salt A(t) in the tank at the time (dA / dT) / (A / 100) = 0, A(0) = 30

It is Given that a large tank holds 400 gallons of water, in which 80 ponds of salt have been dissolved, given that pure water is pumped into the tank at a rate of 8 gallons/min. here we have to find the differential equation for the amount of salt in the tank at the time when the solution is well stirred. we have to multiply both 400 gallons of water and pumped water at the rate of 8 gallons/min.

dA / dT = Rin - Rout

Rin = 0

Rout = A(t) / 400 * 8

        = A / 50

For groceries to be delivered, one particular grocery store charges 3% of the whole purchase price. The total price the store charges to deliver $140 worth of groceries will be $144.20.

A % in mathematics is a quantity or ratio that is stated as a fraction of 100 (from the Latin per centum, "by a hundred"). Although abbreviations "pct.", "pct.", and occasionally "pc" are also used, percent symbol, "%," is frequently used to indicate it. A % lacks dimensions and has no associated unit of measurement.

It should be mentioned that a certain grocery store charges a delivery fee equal to 3% of the entire purchase price.

Consequently, the following is the total the store will charge to deliver $140 worth of groceries:

= Percentage charged × Cost+ Cost

= 3% × $140+$140

= 0.03 × $140+$140

= $4.20+$140
