If x = 3x + 4 - 1 , then what does -x equal?

Answers

Answer:

-4/5 = x

Step-by-step explanation:

Answer:

3/2

Step-by-step explanation:

x = 3x + 4 - 1

we can subtract 1 from 4

x = 3x + 3

subtract 3x from both sides

-2x = 3

divide both sides by -2

x = -3/2

so -x would equal -(-3/2) = 3/2

A rectangular courtyard has an area of 104 square yards. The length of the playground is 3 yards shorter than twice the width. Find the
length of the playground,
O 10 yards
O 15 yards
O 8 yards
O 13 yards

Answers

The answer should be D

The length of the playground is 13 yards.

What is the area if the rectangle?

A = l × w

where 'l' represents the length of the rectangle

'w' represents the width of the rectangle

For given example,

area of rectangular courtyard = 104 square yard

Let the length of the playground be l cm and the width be w cm.

Then, l = 2w - 3

The area of a rectangle is,

[tex]A=l\times w\\\\104=(2w-3)\times w\\\\104=2w^2-3w\\\\2w^2-3w-104=0\\\\w=\frac{-b\pm \sqrt{b^2 -4ac} }{2a} \\\\w=\frac{3\pm\sqrt{9-4(2)(-104)} }{4} \\\\w=\frac{3\pm\sqrt{841} }{4} \\\\w=\frac{3\pm29}{4}\\\\w=\frac{3+29}{4} \text{ or } w=\frac{3-29}{4}\\\\w=\frac{32}{4}\\\\w=8\\\\[/tex]

So, the width of the playground is 8 cm.

Now, we find the length of the rectangular playground.

[tex]l=2w-3\\\\l=2(8)-3\\\\l=16-3\\\\l=13~yards[/tex]

Therefore, the length of the playground is 13 yards.

Answer:

M: (-12,-19) N:(20,5)

Step-by-step explanation:

M: Find the distance of the opposite side to angle N to figure out the distance of the same side of the side with angle M.

20-(-3)= 23

Use the distance to find the coordinates.

-4+23= 19

N: Find the distance of the opposite side to angle M to figure out the distance of the same side of the side with angle N.

-12-(-3)=-9

Use the distance to find the coordinates.

-4+9= 5

Answer:

N=(20,5)

M=(-12,19)

Step-by-step explanation:

Rectangular Coordinates

The diagram shows two identical and rotated triangles (assumed as right triangles).

We can visually identify there is a hypotenuse, a shorter leg, and a longer leg on each triangle.

The longer leg on the triangle at the left is the one that passes through (-12,-4) and M and should have the same length as the leg on the triangle at the right that passes through (-3,-4) and (20,-4). Subtracting the x-coordinates of these points we have its length = 20 - (-3) = 23.

The coordinates of M are (-12,y), where y = -4+23 = 19.

M=(-12,19)

The shorter leg has a length calculated as the difference in the x-coordinates of (-12,-4) and (-3,-4). L= -3+12 = 9.

The coordinates of N are (20,-4+9) = (20,5)

N=(20,5)

Answer:

choice 3

Step-by-step explanation:

Answer:

Fourth Option

Step-by-step explanation:

The perimeter of a shape is all sides added. So, if you do 2x + 2x + (x+1) + (x+1), you would get 6x+2. To get the answer to the question, you verify to see which one of the options equal to 6x+2.

First option:

2x(x+1) and 2(2x) + 2(x+1). You find what this equals. 2x(x+1) = 2x^2+2x so we can automatically elimate this one.

Second option:

2x(x+1) and 2x+2x+2x+1. Here again you see 2x(x+1) which equals 2x^2+2x and is not correct so we eliminate this.

Third option:

4x(2x+2) and 2x(x+1) + 2x(x+1). Once more you see 2x(x+1) but added to 2x(x+1) which would basically equal 2x^2+2x *2. Therefore, it's not this one.

Fourth option:

6x+2 and 2x+(x+ 1) +2x + (x+ 1). Now this one looks right because we already got 6x+2 and this is the only option that presents that but also because we initially solved 2x + 2x + (x+1) + (x+1) and this equals 2x+(x+ 1) +2x + (x+ 1).

I guess you don't really have to solve each of them you can kinda see and tell that the last one seems right but if you're not sure you should use the process above.

I hope this helped!

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

It is given that:

The right-angle triangle is shown in the picture.

The right-angle triangle is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

As the two lines are parallel to each other and a transversal is intersect the parallel lines so the angle would be same as 32 degrees

The angle A = 32 degrees

Thus, the measure of the angle A is 32 degrees or the measure of the angle of elevation is 32 degrees option (b) 32 degrees is correct.

Marianne has a scarf that is 5 inches longer than it is wide. if the area of her scarf is 84 square inches. what are the dimensions of her scarf?​

Answers

Answer:

The dimensions of Marianne scarf = 12  × 7  inches

The length of the scarf  =12inches

The width of the scarf = 7 inches

Step-by-step explanation:

Step(i):-

Let 'x' be the width of the scarf

Given that the length of the scarf = x+5

The area of the rectangle = length × width

Given that the area of the rectangle (scarf) = 84 square inches

Step(ii):-

   length × width = 84

    (x+5) × x = 84

    x² + 5x - 84 =0

   x² + 12 x - 7 x - 84 =0

   x(x+12) -7( x+12) =0

    (x-7)(x+12) =0

    x -7 =0  and x+12=0

     x =7   and x= -12

Step(iii):-

We have to choose x =7

The length of the scarf = x+5 = 7+5 =12inches

The width of the scarf = x = 7 inches

Mojave art club is selling t shirts for a fundraiser. A local company charges $35 to set up the logo and $4.25 per t shirt if x t shirts are printed by the business.

If the art club charged $10 per shirt how many shirts would need to be sold to cover their costs?

function C(x)=35+4.25x/x

Answers

Answer:

At least 7 shirts would need to be sold to cover their costs

Step-by-step explanation:

Cost of producing x t-shirts.

The cost of producing x t-shirts is a flat fee of 35 plus 4.25 per t-shirt. So

[tex]C(x) = 35 + 4.25x[/tex]

Earnings of selling x t-shirts:

Charges $10 per t-shirt, so it earns 10 for each t-shirt it sells.

[tex]E(x) = 10x[/tex]

How many shirts would need to be sold to cover their costs?

To cover the costs, we need that the earnings are equal or higher than the costs. So

[tex]E(x) \geq C(x)[/tex]

[tex]10x \geq 35 + 4.25x[/tex]

[tex]5.75x \geq 35[/tex]

[tex]x \geq \frac{35}{5.75}[/tex]

[tex]x \geq 6.09[/tex]

Since we cannot sell a decimal part of a shirt, at least 7 shirts would need to be sold to cover their costs

Solve for v 29 = -8v - 7 + 5v Simplify your answer as much as possible​

Answers

Answer:

v = -12

Step-by-step explanation:

29 = -8v - 7 + 5v

Combine the 'like terms':  

29 = (-8v + 5v) - 7

29 = -3v -7

Add 7 to both sides:

29 + 7 = -3v -7 +7

36     =    -3v + 0

36      =    -3v

Divide both sides by the coefficient in front of the variable 'v' because we want to get 'v' all by itself. So, divide by -3.

36/-3 = -3v/-3

   -12  =  v

And that is the answer, v is negative twelve

Answer:

v=

Step-by-step explanation:

29= -8v- 7 + 5v

-8v + 5v - 7 = 29

-3v - 7 = 29

-3v - 7 + 7 = 29 + 7

-3v = 36

-3v ÷ -3 = 36 ÷ -3

v = -12
