Don’t understand which expression represents the perimeter of the rectangle

To meet or beat the sales goal, the inequality 72x + 90y ≥ 360 can be used to represent the number of games that must be sold every day. The graph of this inequality would show the region above or on the line 72x + 90y = 360.

To meet or beat the sales goal of at least $360 per day, we can set up an inequality based on the profits from selling games. Let x be the number of portable game systems sold and y be the number of standard game systems sold. The inequality representing the number of games that must be sold every day is 72x + 90y ≥ 360.

To graph this inequality, we can plot the points on a graph where each point represents a combination of x and y. Then we shade the region that satisfies the inequality, which is the region above or on the line 72x + 90y = 360.

Answer:

Step-by-step explanation:

3(x + 1) + 4x + 3 = 34......distribute thru the parenthesis

3x + 3 + 4x + 3 = 34....combine like terms

7x + 6 = 34....subtract 6 from both sides

7x = 34 - 6

Step-by-step explanation:

we know that

The volume of a rectangular prism is equal to

In this problem we have

[tex]L=ab^2\\W=ab^3\\H=a^2b[/tex]

substitute

Applying property of exponents

[tex]V=(a^{4})(b^{6})\ units^3[/tex]

The two numbers being asked in the question are 4 and -1.

This question can be solved using a system of linear equations. Let's call the first number x and the second number y.

From the first statement, we can create one equation: 2x + 4y = 4

From the second statement, we can create another equation: x - y = 5

To solve this system, we can use substitution or elimination method. If we multiply the second equation by 2, we get 2x - 2y = 10. Now, we can subtract the second equation from the first: (2x + 4y) - (2x - 2y) = 4 - 10, which simplifies to 6y = -6. Dividing both sides by 6, we get y = -1.

Substitute y = -1 into the equation x - y = 5, we get x - (-1) = 5. Therefore, x = 5 - 1 = 4.

So, the first number x is 4 and the second number y is -1.

The domain of a graph is the set of input values the function can take

The domain of the graphed function is (c) {x | x is a real number}

The equation of the graph is given as:

[tex]y = \sqrt[3]{x -1} + 3[/tex]

The above function is a cubic function, and a cubic function can take any real number as its input

This means that, the input values of the function [tex]y = \sqrt[3]{x -1} + 3[/tex] is the set of real numbers

Hence, the domain of the graphed function is (c) {x | x is a real number}

The domain of the translated cube root function y = ∛(x - 1) + 3 is {x | x is a real number}, since cube root functions accept all real numbers.

The graph of the function y = ∛(x - 1) + 3, which is a cube root function, is a translated version of the parent function y = ∛x. The translation involves shifting the graph to the right by 1 unit and up by 3 units. Given that a cube root function, like y = ∛x, can accept any real number as an argument because there are real cube roots for all real numbers, the domain of the translated function would also be all real numbers. This remains true even after the function is translated. Hence, the domain of the graphed function is {x | x is a real number}.

Answer:

135m^2

Step-by-step explanation:

length = l

width = w

l + l + w + w = 48

l = w+6

w+6 + w+6 + w + w = 48

4w + 12=48

4w=36

w=9

l=15

15*9=135

Answer:

A = 135m²

Step-by-step explanation:

Write equations to represent the problem.

l = w + (6m)        The length is 6m more than the width

P = (48m)        Perimeter is 48m

***We put brackets around numbers with the "m" to avoid confusing the units with a variable.

The formula for perimeter of a rectangle is P = 2(l + w)

Substitute "l" and "P" into the perimeter formula with the equations above. Simplify, then isolate "w".

P = 2(l + w)        

(48m) = 2(w + (6m) + w)        Collect like terms (w + w = 2w)

(48m) = 2(2w + (6m))        Distribute over brackets

(48m) = 4w + (12m)        Start isolating "w"

(48m) - (12m) = 4w + (12m) - (12m)        Subtract 12m from both sides

(36m) = 4w        

4w/4 = (36m)/4        Divide both sides by 4

w = 9m        Width of rectangle

Find "l" using the formula for length. Substitute the width.

l = w + (6m)        

l = (9m) + (6m)        Add

l = 15m        Length of rectangle

Use the formula for the area of a rectangle A = lw.

Substitute the values we found for length and width.

A = lw        

A = (15m)(9m)        Multiply

A = 135m²        Area of rectangle

Therefore the area of the rectangle is 135m².

Answer:

D.)<-50.5, 58.1>

Step-by-step explanation:

The vector can be decomposed into its x and y components using trigonometry.

The x and y components of the vector, together with the vector length forms a right triangle, as shown in the figure attached.

The x-component of the vector is given by

[tex]sin (-41^o)=\dfrac{x}{77}[/tex]

[tex]x=77*sin (-41^o)[/tex]

[tex]x=-50.5[/tex]

And the y-component of the vector is given by

[tex]cos(-41^o)=\dfrac{y}{77}[/tex]

[tex]y=77*cos(-41^o)[/tex]

[tex]y=58.1[/tex]

Thus, the vector as an ordered pair is represent by

[tex]\boxed{ (-50.5, 58.1)}[/tex]

which is choice D.

I'm guessing you mean (6/7)x+(1/2)=7/8

Subtract 1/2 (also 4/8) from both sides:  (6/7)x=3/8

Divide both sides by 6/7: x=21/48=7/16

So x is 7/16

Answer:

Step-by-step explanation:

-2x > 10

x < -5

So x can be -6, -7, -8, -9

Any number less than -5 is a solution.

The listed ones are the solutions because they satisfy the the inequality,

-2x > 10

x = -6, -2(-6) > 10 12 > 10

x = -7, -2(-7) > 10 14 > 10

x = -8, -2(-8) > 10 16 > 10

x = -9, -2(-9) > 10 18 > 10

To factor the expression 15x - 25 using the greatest common factor (GCF), divide each term by the GCF. The factored form is 5(3x - 5).

To factor the expression 15x - 25 using the greatest common factor (GCF), we need to find the largest number that divides both terms evenly. In this case, the GCF is 5. We can then divide each term by 5 to factor out the GCF:

15x ÷ 5 = 3x

-25 ÷ 5 = -5

Therefore, the factored form of the expression 15x - 25 is 5(3x - 5).

The expression 15x - 25 is factored by finding the Greatest Common Factor, which is 5, and then dividing each term by 5 to get the factored expression 5(3x - 5).

To factor the expression using the Greatest Common Factor (GCF), we need to identify the highest number that divides both coefficients in the expression 15x - 25. In this case, both 15 and 25 are divisible by 5, so 5 is the GCF of the expression. Applying the distributive property, we factor out the GCF:

Now, the expression 15x - 25 is fully factored as 5(3x - 5).

Answer:

Step-by-step explanation:

y= 16

x=15

Using the substitution method,

The value of x is -1 and y is 3.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 8 is an equation.

We have,

2x + 6y = 16 _____(1)

3x - 5y = -18 ______(2)

From (1) we get,

2x = 16 - 6y

x = (16 - 6y)/2

Substituting in (2).

3x - 5y = -18

3 x (16 - 6y)/2 ) - 5y = -18

3 x (8 - 3y) - 5y = -18

24 - 9y - 5y = -18

24 + 18 = 9y + 5y

42 = 14y

y = 42/14

y = 3

And,

x = (16 - 6y)/2

x = (16 - 6 x 3) / 2

x = (16 - 18) / 2

x = -2/2

x = -1

Thus,

x = -1 and y = 3.

Answer: 16x² + 8x + 1

Step-by-step explanation:

(4x + 1)(4x + 1)

This expansion can be done in two ways either by direct expansion or by indirect expansion

(1) Direct expansion

(4x + 1)(4x + 1 )

4x X 4x + 4x X 1 + 1 X 4x + 1 X 1

= 16x² + 4x + 4x + 1

= 16x² + 8x + 1

(2) Method

This can be written thus:

(4x + 1 )(4x + 1 ) = (4x + 1 )²

= (4x)² + 2( 4x X 1 ) + 1²

= 16x² + 2(4x) + 1

= 16x² + 8x + 1.

(4x + 1)(4x + 1)

4x · 4x = 16x²

4x · 1 = 4x

1 · 4x = 4x

1 · 1 = 1

16x² + 4x + 4x + 1

16x² + 8x + 1

We can completely define a line equation by only knowing two points on the line, so we will use that to find our line's slope.

The slope is positive. (We will see that the slope is equal to 1/5).

The first general rule is that, if the line, readen from lest to right increases, then the slope is positive. (Here by the description we know that it increases).

But let's find the slope to see this.

If we know that the line passes through two points (x₁, y₁) and (x₂, y₂) then we can write the slope as:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Here we can use two of the given points to find the slope, I will use the first two: (-5, -1) and (0, 0)

We will get:

[tex]a = \frac{0 - (-1)}{0 - (-5)} = \frac{1}{5}[/tex]

So the slope is 1/5, which is positive.

Then the correct option is the first one.

Step-by-step explanation:

we know that

The general form of absolute value equation is

where

The variable a, tells us how far the graph stretches vertically, and whether the graph opens up or down
