Answer: 4(6-y)

Step-by-step explanation: Since you are multiplying 4 by the difference of 6 and y, you put 6 and y in parenthesis with the 4 on the outside. Then 6-y goes inside the parenthesis.

Also the second one would be (6+9)n=20

The parallel plane is the plane that has the same in-between distance at all points on the plane so plane ABF is parallel with plane DCG so option (C) is correct.

The plane is a two dimension(2D) surface that has a surface area.

We can draw lines on a plane and two or more planes can intersect or parallel.

If two planes are parallel then the perpendicular distance between both planes must be the same.

The angle of inclination of two parallel planes with a single reference plane is also the same.

In the given cuboid the plane ABF is parallel with plane DCG.

So, ABF || DCG.

Hence "The parallel plane is the plane that has the same in-between distance at all points on the plane so plane ABF is parallel with plane DCG".

The time would be 6 AM at the place at 90-degree West longitude.

This is a problem with coordination and time. We can solve this problem by using a few steps.

We should recall that each degree west is equivalent to 4 minutes before.

The given place is at 90-degree West longitude. Therefore, the total time difference is (90 × 4) = 360 minutes.

360 minutes is equal to 360/60 = 6 hours.

The original price of the laptop is $479.40.

Given:

Discount on the laptop = 25%

HST paid on the laptop = 13%

Total price of the laptop = $677.15

Let the original price of the laptop be $x.

Price of the laptop after 25% off = x + 25% of x

                                                      = $ (125x/100)

Total Price of the laptop after paying 13% HST

= (125x/100) + 13% of (125x/100)

= (125x/100) + (65x/400)

= $ (565x/400)  

Now, it is given that the total price paid is $677.15 at the cash register.

565x/400 = 677.15

x = (677.15 × 400)/565

x = $479.40

Answer:

Step-by-step explanation:

1) First find the y-intercept point

You can find it easily by finding the number without the variable. In this case, it is -1. With this draw a point on the y-axis line down to -1.

2) Find the slope.

Next, you can find a point by substituting a number for x. So in this example, I will be subbing x for 1.

y = -3(1) - 1

y= -3 - 1

y= -4

So there will be a point at (1,-4).

The box contains 40 bolts, each weighing 280 g. The package weighs 405 g when there are 65 bolts inside. The bolt's mass is thus 5g, while the box's mass is 80g.

In many practical applications in daily life, linear equations are a crucial tool in science.

They let scientists, among other things, make predictions, compute rates, and characterize connections between two variables in the physical world. In order to see trends, linear equations are often graphed.

A condition on a variable is an equation when it ensures that two expressions in the variable have the same value.

The variable’s value for which the equation holds true is referred to as the equation’s solution.

Bolts are kept in a box for an assembly line. The package weighs 280 g when there are 40 bolts inside.

Let ‘x’ be the mass of each bolt and ‘y’ be the mass of the box, then we have:

40x + y = 280(1)

65x + y = 405(2)

If we subtract these 2 equations that are for (2) – (1) we get:

25x = 125

X = 5

Using (1) we get

Y = 280-40x

Y = 280-40*5

Y = 80.

Hence the mass of the bolt is 5g and the mass of the box is 80g.

Answer:

Step-by-step explanation:

Exponents are powers or indices. An exponential expression consists of two parts, namely the base, denoted as b and the exponent, denoted as n. The general form of an exponential expression is b n.

How to Subtract Exponents?

The operation of subtracting exponents is quite easy if you have a good understanding of exponents. In this article, you will learn the rules and how to apply them when you need to subtract with exponents.

But before we can embark on subtracting with exponents, let us remind ourselves some of the basic terms about exponents.What is an exponent?

Well, an exponent or power denotes the number of times a number is repeatedly multiplied by itself. For example, when we encounter a number written as, 53, it simply implies that 5 is multiplied by itself three times. In other words, 53 = 5 x 5 x 5 = 125The same format of writing exponents applies with variables.  Variables are represented by letters and symbols. For instance, when x is multiplied repeated by itself 3 times, then we write this as; x3. Variables are usually accompanied by coefficients. A coefficient is therefore an integer that is multiplied by variable.

For instance, in 2x3, the coefficient is the number 2 and x is the variable. When a variable has no number before it, the coefficient is always 1. This is also true when a number has no exponent. The coefficient of 1 is normally negligible, and therefore cannot be written with a variable.

Subtraction of exponents really does not involve any a rule. If a number is raised to a power. You simply compute the result and then perform the normal subtraction. If both the exponents and the bases are the same, you can subtract them like any other like terms in algebra. For example, 3y – 2xy = x y.

Subtracting exponents with the same base

Let’s explain this concept with the help of a few examples.

Example 1

23– 22 = 8 – 4 = 4

53 – 52 = 75 – 25 = 50

Subtract x 3 y 3 from 10 x 3 y 3

In this case the coefficients of exponents are 10 and 1

The variables are like terms and hence can be subtracted

Subtract the coefficients = 10 – 1

= 9

Thus, 10x 3y 3– x 3y 3 = 9 (xy)3

You can notice that, the subtraction of exponents with like terms is done by finding the difference of their coefficients.

Subtract 8x2 – 4x2

In this case, the variables 4x2 and 8x2 are like terms and their coefficients are 4 and 8 respectively.

= 8x2 – 4x2

= (8-4) x2.

= 4 x2

Work out (-7x) – (-3x)

Here, -7x and -3x are like terms

= -7x – (-3x)

= -7x + 3x,

= -4x.

15x – 4x – 12y – 3y

Subtract like terms

15x – 4x = 11x

12y – 3y = 9y

Thus, the answer is 11x – 9y.

Subtract (4x + 3y + z) – (2x + 3y – z).

These variables are like terms

(2x + 3y – z) – (4x + 3y + z)

Open the parenthesis;

= 2x + 3y – z – 4x – 3y – z,

Rearrange the like terms, and perform the subtraction

= 2x – 4x + 3y – 3y – z – z

= -2x + 0 – 2z,

= -2x – 2z

Subtracting exponents with different base

Exponents with different bases are computed separated and the results subtracted. On the other hand, variable with unlike bases can not be subtracted at all.  For, example subtraction of a and b can not be performed and the result is just a -b.

To subtract a positive exponents m and negative exponents n, we just connect both the terms by changing the subtraction sign to a positive sign and write the result in the form of m + n.

Therefore, subtraction of a positive and a negative unlike exponents m and -n = m + n.

Example 2

42 – 32 = 16 – 9 =7

Subtract: 11x – 7y -2x – 3x.

= 11x – 2x – 3x – 7y.

= 6x – 7y

Evaluate 3x2 – 7y2

In this case, the two exponents 3x 2 and 7y2 are unlike terms and so it will remain as it is.

Here 3x and 7y both are unlike terms so it will remain as it is.

Therefore, the answer is 3x2 – 7y2

Evaluate 15x – 12y – 11x

= 15x5 – 11x5 – 12y5

= 4x5 – 12y5

The maximum Area that can be enclosed will be 5000 square feet.

In the given question, it is stated that 200 feet of fencing will be done to enclose a rectangular plot with borders on a river. It has a long side on the border of a river which does not needs fencing. We need to find out the Length and Width of the plot that will maximize the area and also find out the Maximum area that can be enclosed.

It is given that the total length of the fence is 200 feet.

Let the length of the plot be l

let the width of the plot be w

=> Total Perimeter will be = l + 2w because the longer side or 1 side of length does not need fencing. Putting the perimeter as 200 we get

=> l + 2w = 200     => Equation (1)

Now, we know the Area of the plot will be l*w,

By equation (1) we get l = 200 - 2w, Putting the values in the Area:

=> Area = (200-2w) * w

=> A = 200w - 2w²

For maximum Area, the derivative of A with respect to w will be 0

=> [tex]\frac{dA}{dW} = 200 - 4w[/tex]

=> [tex]0 = 200 - 4w[/tex]

=> w = 50

Putting w = 50 in Equation (1) we get

=> l = 100

We got our Length l = 100 feet, and Width w = 50 feet. Now we will Calculate the maximum Area to enclose.

=> Area = l*w

=> A = 100*50

=> A = 5000

Hence, the Maximum area to enclose will be 5000 square feet.
