I also provided the formula on how to calculate the slope between the points

Variable x as the subject of the equation given is expressed as: x = p(m - n).

To make a variable the subject of a formula implies that we express the equation in terms of the variable. Thus, to make a variable the subject of the formula, we have to make the variable stand alone on one side of the equation.

Given the equation, m = n + x/p, make x the subject as explained below:

m = n + x/p [given]

Subtract n from both sides

m - n= n + x/p - n (subtraction property of equality)

m - n = x/p

Multiply both sides by p

p(m - n) = x/p(p) (multiplication property)

p(m - n) = x

x = p(m - n)

They plant a total number of 480 seeds.

In the given question, Chrystal and her grandmother plant seeds in the garden. They plant a total of 4 types of seeds: Squash, Corn, Sunflower, and Tomato. They plant 6 rows of each type of seed. Also, each row has 20 seeds. We have to calculate the total number of seeds that they plant.

Given that,

=> Total number of types of seeds, T = 4

=> Number of rows, R = 6

=> Number of seeds in each row, S = 20

To calculate the Total Number of seeds planted we use the formula:

=> Total = T * R * S, Putting values we get:

=> Total = 4 * 6 * 20

=> Total = 480

Hence, the Total number of seeds planted is 480.

4x (3x + 4) - 6 (3x + 4)

12x² + 16x - 18x - 24

12x² - 2x - 24

The output value of f( -4 ) in the function f(x) = -x² - 4x + 42 is 42

A function is simply a relationship that maps one input to one output. Every x-value can only have one y-value to qualify as a function.

Given the data in the question;

To find the output value of f( -4 ), replace all the occurrence of x with -4 in the function and simplify.

f( x ) = -x² - 4x + 42

f( -4 ) = -(-4)² - 4(-4) + 42

f( -4 ) = -( 16 ) + 16 + 42

f( -4 ) = -16 + 16 + 42

f( -4 ) =  42

Therefore, the output value of f( -4 ) is 42, this forms an ordered pair of (-4, 42).

The quadratic equation will be; 3x² + 6x + 9

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Given that roots are x = -3 and x = - 1, and whose leading coefficient is 3.

The factors are; (x + 3) and (x + 1)

f(x) = a(x + 3)(x + 1)

As, a = 3.

Then we get;

f(x) = 3(x + 3)(x + 1)

= 3(x² + 2x + 3)

= 3x² + 6x + 9

The approximate side length of a square game board with an area of 160in² is equal to 12.6 inches.

As given in the question,

Area of the square game board is equal to 160in².

Let 'x' inches be the side length of the square game board.

Area of the square game board = (side length)²

⇒ 160 = ( x )²

Take square root both the sides we get,

    x = √160

⇒ x = 12.649 inches

⇒ x = 12.6 inches( approximately)

Therefore, the approximate side length of a square game board with an area of 160in² is equal to 12.6 inches.

The expression in term numerator and denomerator of P the write answer would be

Sol-

we have a deal an arrangement where, at the end of 5 years, the value of the car is going to be a fifth, the original price. So that's what i have written here after 5 years, the value of the car will be the price, the original price divided by 5 point. What we also know is that at 0 years, our initial value, the output here- should be the price of the car. So what we're going to do is when we use these 2 values to find the slope of this line, so we're going to do y 2, minus 1 y 1 over x, 2 minus x 1. It doesn't matter which 1 is y 2 and which 1 is y 1 as long as you're consistent here, i'm going to do p minus p over 5, and since i started here in the numerator, i need to start there in the denominator.

So we know here that x equals 4 we're doing that in the problem. So i'm goin t go ahead and replace this right here. We'Re gonna have y equals 16 p over negative 25 plus p, and if we get a common denominator here to add this, we have y equals 16 p plus 25 over 25. With this p right here, because it's gonna be 25 p over 25 here and then i recognize that are y value here, that was that was v or value here. All right and, let's see 25 p minus 16 p is going to give us 9 p. All right, so 9 p over 25 is going to be the value of the car, giving the original price p after 4 years.

Answer:

53 sets

Step-by-step explanation:

730 - 204 = 526

526 / 10 = 52 r 6

therefore he'd have to buy 53 sets to have enough knives.

There are 53 number of sets of knives Jordan could buy for the restaurant to have enough knives.

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The restaurant needs at least 730 knives.

There are currently 204 knives.

And, each set on sale contains 10 knives.

Now,

By the given condition, we formulate;

⇒ 730 ≤ 204 + 10x

Solve for x as;

⇒ 730 ≤ 204 + 10x

⇒ 730 - 204 ≤ 204 + 10x - 204

⇒ 529 ≤  10x

Divide by 10 as;

⇒ 52.9 ≤ x

After rounding, we get;

⇒ 53 ≤ x

Thus, There are 53 number of sets of knives Jordan could buy for the restaurant to have enough knives.

Total Volume of a cylinder

V = π R² H

where R - base radius

H = height

Given diameter of base = 30m, base radius R = 30/2 = 15

H  = 20m

Volume = π x 15² x 20 = 4500π m³ = 14,137.16694 m³

The number of tiles measuring 20cm by 50cm  that are needed to completely cover a wall 4m by 8m is :320.

First step is to convert the Meters to Centimeters

4m = 400cm

8m = 800 cm

Hence,

4m by 8m = 400 cm × 800 cm

4m by 8m = 320,000 cm²

Second step is to determine the how many tiles are needed

Number of needed tiles =  320,000 cm² / ( 20 cm × 50 cm)

Number of needed tiles =  320,000 cm² /1,000 cm²

Number of needed tiles =  320

Therefore 320 tiles are needed.

the total price paid for a pair of shoes after tax is included is $37.1.

A sales tax is a tax paid to the government for sales of certain types of goods and services.

According to the question,

Cost of the shoes =  $35.             (given)

Total amount/price paid = cost + tax

As the tax percentage is not given in the question, we will assume it to be 6% for example. Then,

Tax amount = 6% of $35

= 6/100*35

= $2.1

Now, total price = cost + tax

= $35+$2.1

= $37.1

Therefore, we conclude that the total price paid for a pair of shoes after tax is included is $37.1.

In terms of x and y, Julia's withdrawal from her savings account was equal to y/4 + x/12.

An expression obtained by performing a finite number of algebraic fundamental operations on symbols representing numbers.

Both Ang and Julia have savings balances of x and y dollars, respectively.

Ang = x dollars

Julia = y dollars

Ang offers Julia a third of his savings, which she then transfers to her own savings account.

Amount in Julia's account = (1/3)x + y

Julia then spends a quarter of the total into her savings account.

Amount of money Julia spent = 1/4 × [(1/3)x + y]

                                                 = (1/12)x + (1/4)y
