Answer: 2 and 1 are the only factors

Step-by-step explanation: The definition of factor is the numbers that can be multiplied to get the said number. In this case the said number is 2. The only numbers that multiply to get 2 are 2 and 1.

Answer:

10.2

Step-by-step explanation:

F(n) is basically a fancy substitute for y

25= 1.25n + 12.25

subtract 12.25 from both sides

12.75=1.25n

n=10.2

plug back in to double check

1.25(10.2) + 12.25

it equals 25, therefore the answer is

10.2

✺ Divide both sides by −3. Since −3 is negative, the inequality direction is changed:

✺ Divide −9 by −3 to get 3. Since they are both negatives it turns into a positive:

✺ Swap sides so that all variable terms are on the left hand side. This changes the sign direction once more:

✺ Add 2 to both sides:

✺ Add 3 and 2 to get 5:

✺ Divide both sides by 5. Since 5 is positive, the inequality direction remains the same:

✺ Divide 5 by 5 to get 1:

Answer:

[tex]\boxed {x < 1}[/tex]

Step-by-step explanation:

Solve the following inequality:

[tex]-9 < -3(5x - 2)[/tex]

-When you are dividing an integer by a negative integer, then the inequality sign changes. So, divide both sides by [tex]-3[/tex]:

[tex]\frac{-9}{-3} < \frac{-3}{-3} + 5x - 2[/tex]

[tex]3 > 5x - 2[/tex]

-Switch sides:

[tex]5x - 2 < 3[/tex]

-Add [tex]2[/tex] to both sides:

[tex]5x - 2 + 2 = 3 + 2[/tex]

[tex]5x < 5[/tex]

-Divide both sides by [tex]5[/tex]:

[tex]\frac{5x}{5} < \frac{5}{5}[/tex]

[tex]\boxed {x < 1}[/tex]

Answer:None

Step-by-step explanation:

You can write a statement of proportionality without any additional information:

weight = k × length for some constant k

If you need to know the specific weight of a specific length, then you need to know the constant of proportionality (the value of k).

Answer:

h(t) = -3(t-8)(t+4). and 8 minutes

Step-by-step explanation:

The function can be written as: h(t) = - 3(t² - 4t - 32). As per quadratic equation, after take off, the drone will land on the ground after 8 minutes.

A quadratic equation is an equation that contains a variable with highest degree of 2.

Given, the height of the drone t minutes after take off is modeled by

h(t) = - 3t² + 12t + 96 = - 3(t² - 4t - 32)

Therefore, the function can be written as: h(t) = - 3(t² - 4t - 32)

Therefore, we can write the equation as:

t² - 4t - 32 = 0

⇒ t²- 8t + 4t - 32 = 0

⇒ t(t - 8) + 4(t - 8) = 0

⇒ (t + 4)(t - 8) = 0

Hence, (t + 4) = 0 and (t - 8) = 0

Therefore, t = -4, 8.

As 't' can't be negative, therefore, t = 8.

Therefore, after take off, the drone will land on the ground after 8 minutes.

Answer:

First add all the equations like (11y-32)+(3x-16)+(6x+7)=180

Step-by-step explanation:

You would first combine all the like terms so put all the variables on one side and the numbers on the other. After you have done that, you would just solve.

because if you subtract 7 by 3.2 you'll get

3.8, 3.8 will be the total of rain if you add week 1 2 4 , then youll have to find the average by dividing 3.8 by 3 youll get 1.26 . so that means the average lenth of the rain for 1 2 4 is 1.26 inches

Answer:

308m

Step-by-step explanation:

11+22+33+44+55+66+77=308

Given :

A rectangle with a length of 3 x and height of x. If Kyle uses 18 feet of wood to make the frame.

To Find :

The length of the frame.

Solution :

We know, perimeter of the rectangle is given by :

[tex]P=2(l+b)\\\\P=2(3x+x)\\\\P=8x[/tex]

Now, it is given that 18 feet of wood is used.

So,

[tex]8x=18\\\\x = 2.25\ feet[/tex]

Therefore, length of frame is given by  3x = 6.75 feet.

Hence, this is the required solution.

Answer: A, 6.75

Step-by-step explanation: If the frame is 3 times the width and Kyle uses 18 feet them this the only correct option out of the other 3.

Answer: D

Step-by-step explanation:

Answer: {x,y}={6,21}

Step-by-step explanation:

// Solve equation [2] for the variable  x

  [2]    3x = 18

  [2]    x = 6

// Plug this in for variable  x  in equation [1]

  [1]    2•(6) - y = -9

  [1]     - y = -21

// Solve equation [1] for the variable  y

  [1]    y = 21

// By now we know this much :

   x = 6

   y = 21

We are done

Answer:

y = 2x -6. A dependent system, so all numbers on this line.

Step-by-step explanation:

2x - y = 6

-3y = -6x + 18

In order to solve a system of equations, you want to get isolate y. One equation already has done that for us, so that makes it easier.

2x - y = 6

In order to isolate y in this equation, you must simply subtract 2x from both sides, which would give us:

-y = -2x + 6

Now, you can't leave y negative. Normally you'd divide the y by its variable, but this one doesn't have a variable. so you must divide both sides by -1.

[tex]\frac{-y}{-1} =\frac{-2x+6}{-1}[/tex]

We divide both sides because what you do to one side you must do to the other. This leaves us with the equation:

y = 2x - 6

Now, for the other equation. It's simple since y is already isolated.

-3y = -6x + 18

Once again we will be dividing both sides, but this time it's by -3.

[tex]\frac{-3y}{-3} =\frac{-6x+18}{-3}[/tex]

We are dividing by -3 instead of -1 because y in this equation has a variable of -3. This would give us:

y = 2x - 6

Now, normally in order to get the answer, you must graph both of these equations, but since these equations ended up being the same, the answer is every number that appears on the line. This is called a dependent system.
