Answer:

Not giving you answers, but I'll try to help you find a slope

Step-by-step explanation:

So take the first question.

A slope equals rise/run. The first point is 2,1 and the second is 0,-3.

For rise, take the second numbers you see for each written point (so 1 and -3). Subtract them. For run, take the first 2 numbers (2 and 0)

1--3 is 4

2-0 is 2

So the slope is 4/2 (write it like you would a fraction, 4 over 2). If I messed up, sorry. I don't know much about this yet either.

=-12x^2

Answer:

- 12x²

Step-by-step explanation:

Given

2x(3x - 9x)

= 2x(- 6x)

= - 12x²

⭐ Resolvemos :

  [tex]16(x+3)=4(x+9)\\16x+48=4x+36\\16x-4x=36-48\\12x=-12\\x=-12/12\\\\\boxed{x=-1}[/tex]

⭐ Explicación paso a paso :

        16 (x + 3) = 4 (x + 9)

        16x + 48 = 4x + 36

        16x - 4x = 36 - 48

        12x = -12

        x = -12 ÷ 12

Answer:

The discount rate is 35.3%.

Step-by-step explanation:

Since the price difference is (85-55) = 30 dollars, we can find the discount rate by dividing 30 by the original price, 85 dollars, to get this percentage, 35.5%.

Hope this helped!

Answer:

The discount rate is 35.3%.

Step-by-step explanation:

      Because the price difference is ( 85 - 55 ) = 30 dollars, we can find the discount rate by dividing 30 by the original price, 85 dollars, to get this discount, 35.5%.

Answer:1: 56. 3 squared is 9, times 6 is 56.2: 24. 2 squared is 4, times 6 is 24.3: 80. 56+24=80

Step-by-step explanation:

1. The surface area of cube 1 is 54 sq ft,  the surface area of cube 2 is 24 sq ft,  the total area Abby will paint is 78 sq ft

A cube is a three-dimensional representation of a square. it has 6 faces 2 on the bottom and top, 4 on the sides faces.

We are given that Abby is painting two cubes for an art project.

Cube 1: side length = 3 feet

Cube 2: side length = 2 feet

The surface area of a cube = 6s², where s is the length of one side.

1. Each side of cube 1 is

3 feet x 3 feet, = 9

so, each side has an area of 9 square feet.

Then Multiply by 6 sides and the area

6 x 9 = 54

that is 54 square feet.

2. Each side is 2 feet x 2 feet = 4

so, the area of one side is 4 square feet.

Then Multiply by 6 sides and the area

6 x 4 = 24

That is 24 square feet.

3. the total area = 54 + 24 = 78 square feet

Answer:

$0.125 , so 12.5 cents per pencil

Step-by-step explanation:

[tex]\frac{3.00}{24}[/tex]

You can double check this by doing [tex]0.125*24[/tex] , making sure it equals 3.

Answer:

The pencils cost about 13 cents a pencil.

Step-by-step explanation:

Divide 3 by 24 and you get 0.125 you can round to the nearest hundredth to get 13 cents. Also see if 12 cents is a answer if 13 cents is not available.

Answer:

a) If he ordered 100 feet of tape, will he have enough tape to wrap 28 swords?

No he would not

b) How much will he have left over or how much more will he need?

= He would have 144 inches left over.

Step-by-step explanation:

The sword maker in the cove ordered a special tape to wrap the sword handles with. He knew each sword would need 48 inches of tape. If he ordered 100 feet of tape, will he have enough tape to wrap 28 swords? How much will he have left over or how much more will he need?

From the above question, each sword would need 48 inches of tape

He would need to wrap 28 swords, hence:

1 swords = 48 inches

28 swords = x

x = 28 × 48 inches

= 1344 inches of tapes

Therefore to cover each sword he would need a total of 1344 inches of tape.

He ordered 100 feet of tape

We convert 100 feet to inches

1 foot = 12 inches

100 feet = x

x = 100 × 12 inches

x = 1200 inches

Hence, he ordered 1200 inches of tape.

a) If he ordered 100 feet of tape, will he have enough tape to wrap 28 swords?

100 feet = 1200 inches of tapes

To wrap 28 swords he would need 1344 inches of tape hence, he would not have enough tape to wrap 28 swords.

b) How much will he have left over or how much more will he need?

= 1344 inches - 1200 inches

= 144 inches

He would have 144 inches left over.

Answer:

Given are two complex numbers as

When we add algebraically, we add the real parts and then add the imaginary parts separately

Hence

Geometrically we draw position vector of both the points.  The sum would be resultant of these two vectors.

Step-by-step explanation:

The sum of the complex number in rectangular form is -1 +i

Complex numbers are written in the form x + iy

Given the complex numbers expressed as:

z1 = 8 - i

z2 = -9 + 2i

Take the sum

z1 + z2 = (8 - 9) + (-i+2i)
z1 +z2 = -1 + i

Hence the sum of the complex number in rectangular form is -1 +i

Answer: x = -0.377

Step-by-step explanation:

We have the equation:

4^(5*x) = 3^(x - 2)

Now we can use the fact that:

Ln(A^x) = x*Ln(A)

Then we can apply Ln(.) to both sides of the equation to get:

Ln(4^(5*x)) = Ln(3^(x - 2))

(5*x)*Ln(4) = (x - 2)*Ln(3)

(5*x)*Ln(4) - x*Ln(3) = -2*Ln(3)

x*(5*Ln(4) - Ln(3)) = -2*Ln(3)

x = -2*Ln(3)/(5*Ln(4) - Ln(3)) = -0.377

Here is the solution:

Answer:

The answer to this depends on the accuracy of the way this is transcribed.  If the value on the left side of the equals sign is indeed x, then it would be a rational equation.  If it is meant to be another scalar value though, then this would be a quadratic equation.

Step-by-step explanation:

This depends on the what is on the other side of the equals sign.  If it is a scalar value, then you are guaranteed a proper quadratic equation.  In the example given though:

[tex]x = ax^2 + bx + c[/tex]

This is not actually true.  In this example, we can divide both sides by x, giving us a very different equation:

[tex]x = ax^2 + bx + c\\1 = ax + b + c/x\\ax + c/x = 1b[/tex]

and this equation actually a rational one.

Answer: The answer to this question is that there is no solution to that problem

Step-by-step explanation:

Answer: D. The range stays the same, but the domain changes.

Step-by-step explanation: A function can be reflected over or across an axis. When the function is reflected in the y-axis, it means:

g(x) = f(-x)

i.e, the x-values are opposite to the original function.

In the image below, when we reflected the function across the y-axis, the new one will be drawn at the positive x-axis but still at the negative y-axis as shown in red at the second attachment.

Domain of a function is all the values x can assume. Range of a function is all the results the variable y assume.

According to the new graph, y-values didn't change, so Range stays the same. However, x-values changed their signal. Therefore, domain changes.
