Answer:

-1<=X<=9

Step-by-step explanation:

The inequality is given as the negative 1 < x < 9.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

A number x is at least -1 and no more than 9. Then the inequality is given as

- 1 < x < 9

The inequality is given as the negative 1 < x < 9.

Answer:

  9. y -1 = -1/3(x -0)   or   y -1 = -1/3x

  10. y +3 = -5/6(x -5)

  11. x = 1

  12. y -1 = 4(x -0)   or   y -1 = 4x

Step-by-step explanation:

In every case, the slope is calculated from ...

  m = (y2 -y1)/(x2 -x1)

Then that value is used in the point-slope equation:

  y -y1 = m(x -x1)

__

9) m = (2-1)/(-3-0) = 1/-3 = -1/3

  y -1 = -1/3(x -0)

__

10) m = (3 -(-3))/(0 -5) = 6/-5 = -5/6

  y +3 = -5/6(x -5)

__

11) m = (1 -3)/(1 -1) = -2/0 = undefined

No "y =" equation can be written for a line with undefined slope. The equation for a vertical line through these points with x-coordinate of 1 is ...

  x = 1

12) m = (5 -1)/(1 -0) = 4/1 = 4

  y -1 = 4(x -0)

Answer:

(4, - 0.5 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ]

Here (x₁, y₁ ) = C(1, - 6) and (x₂, y₂ ) = D(7, 5) , then

midpoint = ( [tex]\frac{1+7}{2}[/tex] , [tex]\frac{-6+5}{2}[/tex] ) = [tex]\frac{8}{2}[/tex] , [tex]\frac{-1}{2}[/tex] ) = (4, - 0.5 )

Answer:

$12.75 cupcakes

Multiply the $12.75 x .04 = .51

$12.75 + .51 = $13.26 total

Step-by-step explanation:

Explanation:

The conclusion should be [tex]p \to r[/tex] due to the hypothetical syllogism rule (similar to the transitive rule).

You can make a truth table to show that the premises [tex]p \to q[/tex] and [tex]q \to r[/tex] can both be true at the same time, but the conclusion [tex]p \leftrightarrow q[/tex] is false. Whenever you have all true premises and a false conclusion, then the argument is invalid. True premises must lead to a true conclusion.

The expressions are:

(r-s)(x) = x + 3

(r+s)(x) = 7x - 3

And the value of (r∘s)(3) is unknown without the expression for r(x).

To find the expressions for (r-s)(x) and (r+s)(x) and evaluate (r∘s)(3), where f(x) = 4x and g(x) = 3x - 3, we can substitute these functions into the given expressions.

1. (r-s)(x):

The expression for (r-s)(x) is obtained by subtracting g(x) from f(x):

(r-s)(x) = f(x) - g(x) = (4x) - (3x - 3) = 4x - 3x + 3 = x + 3

2. (r+s)(x):

The expression for (r+s)(x) is obtained by adding f(x) and g(x):

(r+s)(x) = f(x) + g(x) = (4x) + (3x - 3) = 4x + 3x - 3 = 7x - 3

3. Evaluating (r∘s)(3):

(r∘s)(3) means substituting x = 3 into the function composition (r∘s)(x). First, we evaluate s(3):

s(3) = 3(3) - 3 = 9 - 3 = 6

Then, we substitute s(3) into r(x):

(r∘s)(3) = r(s(3)) = r(6)

Since we don't have the expression for r(x), we cannot determine the specific value of r(6) or simplify it further without additional information.

Therefore, the expressions are:

(r-s)(x) = x + 3

(r+s)(x) = 7x - 3

And the value of (r∘s)(3) is unknown without the expression for r(x).

Step-by-step explanation:

Friend is incorrect and the permutations rule should be used instead of just 5!.

Permutations are a process in which the order of items in a set matters. In other words, it refers to the different arrangements that can be made by selecting r items from n different objects, without repeating any of them.

Calculating permutations manually can be time-consuming.

However, the permutations rule simplifies the process.

The permutations rule states that the number of permutations of n distinct objects, taken r at a time, is equal to

nPr = n!/(n-r)!,

where "n" represents the total number of distinct objects and

"r" represents the number of items selected for each arrangement.

So, if you want to find the number of arrangements possible for five distinct letters, you need to use the permutation rule and not just 5!.

This is because 5! represents the number of ways to arrange five distinct objects (letters) in a line, without restrictions, meaning that the same letter can appear twice, or more, in the arrangement.

However, if the five distinct letters are taken two, three, four, or five at a time, then the permutations rule would have to be used.

For example, the number of different arrangements of two letters out of five distinct letters is equal to

5P2 = 5!/3!

= 5 × 4

= 20.

Therefore, your friend is incorrect and the permutations rule should be used instead of just 5!.

Answer:

a² + b² = 22

Step-by-step explanation:

(a + b)² = a² + 2ab + b² ← substitute a + b = 6 and ab = 7

6² = a² + 2(7) + b²

36 = a² + 14 + b² ( subtract 14 from both sides )

To find how many times heavier the planet is than Earth, divide the mass of the planet by the mass of the Earth. For example, I have a 4kg and a 2kg box. To find how many times heavier the 4kg box is than the 2kg box, divide 4 by 2, which would give us 2. Thus, we would arrive at the answer of the 4kg box is 2 times heavier than the 2kg box.

In golf, if you are over par, then your score is represented by values over zero and with a plus. Since Jewels' score was 5 over on the first hole (dang... that's a quintuple bogey (which is horrible)), she had a +5 on the first hole. But for the next 9 holes, she scored  4 under, which is represented by -4. Add 5 and -4 and you get +1. She still has 8 holes left in that round if she wants to get below par.
