3
x - 4y + 2z= -11
2x + y - 2z = 2
A. x = 3, y = 2, z = 4
B. x = 1, y = 4, z = 2
O C. x = 6, y=-3, z = -4
O D. x= 1, y = 6, z = 2

Answers

Answer 1

Answer:

B.

[tex]x = 1 \\ y = 4 \\ z = 2[/tex]

Answer 2

The solution to the system of equations is x-1, y = 4 and z= 2.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have the equation

3x + 2y - 4z = 3

x -4y +2z = -11

2x + y + 2z = -11

Solving the above equation we get

3x + 2y - 4z - 3x + 12y + 6z = 3 + 33

14y + 2z = 36

and, 2x - 8y  + 4z - 2x - y - 2z = -22 + 11

-9y + 2z = -11

So, y =4 and z = 2

and, x = 1

Answers

Answer:

(6)(5)(4) = 120

Step-by-step explanation:

For a permutation, order matters. The equation for a permutation is (n!) / (n-k)! where n represents the total number of items you have to choose from and k represents the amount of items taken into account. Therefore we have

6! / (6-3)! = 6!/3! =(6)(5)(4)(3)(2)(1)/(3)(2)(1) = (6)(5)(4) = 120

Here is another way to picture it:

In this case, we have 6 different dessert options to choose from. Let's say the desserts are A, B, C, D, E, and F

1st favorite (6 choices): A, B, C, D, E, and F. Let's say A is the 1st favorite

2nd favorite (5 choices): B, C, D, E, and F. Let's say B is the 2nd favorite

3rd favorite (4 choices): C, D, E, and F. Let's say C is the 3rd favorite

As you can see we actually have 6! choices for the numerator, but we are only choosing to 3 places, so we don't need the rest of the numbers, which can be represented by 3!

Therefore we have: 6! / (6-3)! = 6!/3! =(6)(5)(4)(3)(2)(1)/(3)(2)(1) = (6)(5)(4) = 120

5x^2+ 15x – 140 = 0
Solve for x

Answers

Answer:

x = 4, -7

Step-by-step explanation:

1) Factor out the common term 5.

[tex]5( {x}^{2} + 3x - 28) = 0[/tex]

2) Factor x² + 3x - 28.

[tex]5(x - 4)(x + 7) = 0[/tex]

3) Solve for x.

x = 4, -7

Therefor, the answer is x = 4, -7.

Answer:

x = 4, -7

Step-by-step explanation:

1. Solve the equation using the quadratic formula

The Quadratic formula provides the solution for [tex]Ax^{2} +Bx+C=0[/tex]

in which A, B, and C are numbers (or coefficients), as follows:

[tex]\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex]

2. Determine the quadratic equation’s coefficients A, B, and C

The coefficients of our equation, [tex]5x^{2} +15x-140=0[/tex], are:

A = 5

B = 15

C = -140

3. Plug these coefficients into the quadratic formula

[tex]\frac{-b+\sqrt{b^{2}-4ac } }{2a}=\frac{-15+\sqrt{15^{2}-4x5x-140 } }{2x5}[/tex]

Calculate the expression inside the parentheses.

Simplify exponents and square roots.

[tex]\frac{-15+\sqrt{15^{2}-4x5x-140 } }{2x5}[/tex]

[tex]\frac{-15+\sqrt{225-4x5x-140 } }{2x5}[/tex]

Perform any multiplication or division, from left to right.

[tex]\frac{-15+\sqrt{225-20x-140 } }{2x5}[/tex]

[tex]\frac{-15+\sqrt{225-2800 } }{2x5}[/tex]

[tex]\frac{-15+\sqrt{3025} }{2x5}[/tex]

[tex]\frac{-15+\sqrt{3025} }{10}[/tex]

to get the result:

[tex]x=\frac{-15+\sqrt{3025} }{10}[/tex]

4. Simplify square root

Simplify 3025 by finding its prime factors.

                    3025

                   /         \

                 /             \

             5                  605

              /                    \

            /                        \

          5                          "121"

           /                            \

         /                                \

        11                                11

The prime factorization of 3025 is 5² • 11²

Write the prime factors.

[tex]\sqrt{3025}[/tex] = √5 • 5 • 11 • 11

Group the prime factors into pairs and rewrite in exponent form.

√5 • 5 • 11 • 11 = [tex]\sqrt{5^{2}x11^{2} }[/tex]

Use rule [tex]\sqrt{x^{2} }[/tex] = x to simplify futher.

[tex]\sqrt{5^{2}x11^{2}}[/tex] = 5 • 11

5 • 11 = 55

5. Solve the equation for x

x = [tex]\frac{-15+55}{10}[/tex]

x = 4

[tex]P(x>12) = 0[/tex]

Step-by-step explanation:

Given

[tex]x = \{1,2,3,4,5,6,7,8,9,10,11,12\}[/tex] --- outcomes

[tex]n(x) = 12[/tex] -- sample size

Required

[tex]P(x > 12)[/tex]

This is calculated as:

[tex]P(x > 12) = \frac{n(x > 12)}{n(x)}[/tex]

[tex]n(x>12) = 0[/tex] because none of the outcomes is greater than 12:

So:

[tex]P(x > 12) =\frac{0}{12}[/tex]

[tex]P(x>12) = 0[/tex]

which one is greater/less than?

-25% or 25%

Answers

Answer:

25% is greater then -25.

Step-by-step explanation:

-25 is in the negiatives, and is to the left of 0. Anything to the left of 0 will be less then anything on the right of 0. :D

-25% will always be less than 25% because a negative number, being less than 0, will always be less than a positive number, being greater than 0.

Thus, -25% is less than 25% or 25% is greater than -25%
