Answer: The system of equations has no solutions.

Step-by-step explanation:

Identify the equation as:

[tex]x + 2y - z=3[/tex]   [Equation 1]

[tex]2x -y + 2z=6[/tex]    [Equation 2]

[tex]x - 3y + 3z=4[/tex]    [Equation 3]

Multiply  [Equation 1]  by -2 and add this to [Equation 2] :

[tex](-2)(x + 2y - z)=3(-2)[/tex]

[tex]\left \{ {{-2x - 4y +2z=-6} \atop {2x -y + 2z=6}} \right.\\ ..........................\\-5y+4z=0[/tex]

 Find another equation of two variables: Multiply  [Equation 3]  by -2 and add this to [Equation 2]:

[tex](-2)(x - 3y + 3z)=4(-2)[/tex]  

[tex]\left \{ {{2x -y + 2z=6} \atop {-2x +6y -6z=-8}} \right.\\........................\\5y-4z=-2[/tex]

Then you get this new system of equations. When you add them, you get:

[tex]\left \{ {{-5y+4z=0} \atop {5y-4z=-2}} \right.\\..................\\0=-2[/tex]

Since the obtained is not possible, the system of equations has no solutions.

The solution to the system of equations x + 2y - z = 3, 2x - y + 2z = 6, and x - 3y + 3z = 4 is (-1, 1, 2) utilizing substitution method.

The subject of this question is to find a solution to the system of linear equations. We can solve this system by methods of either substitution, elimination or matrix - but let's use substitution. First, let's isolate x in the first equation: x = 3 - 2y + z. Then we substitute x into the second and the third equation:

After simplifying these equations, we find y = 1 and z = 2. Plugging these back into x = 3 - 2y + z, we get x = -1. Therefore, the solution to the system is (-1, 1, 2).

Answer:

Step-by-step explanation:

Recall that an equilateral triangle has three equal interior angles, all 60°.  Let b represent the length of the base.  Draw a dashed line from the upper vertex to the base, perpendicularly.  This dashed line represents the height or altitude of the triangle.  

Now construct a triangle whose opposite side is this altitude, whose hypotenuse is b (and whose base is (1/2)b).

The altitude (opp) is then given by sin Ф = opp / hyp = opp / b.  Solving this for the altitude (opp), we get b·sin 60°:

alt (opp)       √3

------------- = ------

  hyp             2

                                                b·√3    

so that 2 alt = b·√3, or alt = ------------

                                                    2

Thus, for any equilateral triangle of side length b, the height of the triangle is

                             √3

alt = height = b · ------

                               2

Please note:  Your problem statement refers to "the equilateral triangle below."  It's important that you share such illustrations, along with all instructions.  In this case your question was general enough so that I could use the definitions of "sine," "equilateral," etc., to come up with a general answer.

Step-by-step explanation:

Answer:

3 ft

Step-by-step explanation:

It is because 3 times 18 is 54 and 3 is 15 less than 18

The width of a rectangle is 3 feet .

The area can be defined as the amount of space covered by a flat surface of a particular shape. It is measured in terms of the "number of" square units (square centimeters, square inches, square feet, etc.)

According to the question

Let length of rectangle = x

The width of a rectangle is fifteen feet less than its length.

i.e,

Width of a rectangle = x - 15

Now,

Area of the rectangle = 54 square feet .

Length * Width = 54

x (x - 15 ) = 54

[tex]x^{2}[/tex] - 15x - 54 = 0

[tex]x^{2}[/tex] - (18-3)x - 54 = 0

[tex]x^{2}[/tex] - 18x + 3x - 54 = 0

x(x-18) +3(x-18) = 0

(x-18) (x+3) = 0

x= 18 , -3

length of rectangle = 18 feet

Width of a rectangle = 18 - 15

                                  = 3 feet

Hence, The width of a rectangle is 3 feet .

Answer:

65°, 70°, 80°, 155°, 170°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 5 ( pentagon )

sum = 180° × 3 = 540°

Sum the given angles and equate to 540

x + x - 5 + x + 10 + 2x + 15 + 2x + 30 = 540

7x + 50 = 540 ( subtract 50 from both sides )

7x = 490 ( divide both sides by 7 )

x = 70

Hence angles are

x = 70°

x - 5 = 70 - 5 = 65°

x + 10 = 7 0 + 10 = 80°

2x + 15 = (2 × 70) + 15 = 140 + 15 = 155°

2x + 30 = (2 × 70) + 30 = 140 + 30 = 170°

Answer:

[tex]x=-1+\frac{\sqrt{78} }{6}[/tex] and

[tex]x=-1-\frac{\sqrt{78} }{6}[/tex]

Step-by-step explanation:

[tex]f(x) = 6x^2 + 12x - 7[/tex]

To find out the zeros of the quadratic function, we apply quadratic formula

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

From the given f(x), the value of a=6, b=12, c=-7

Plug in all the values in the formula

[tex]x=\frac{-12+-\sqrt{12^2-4(6)(-7)}}{2(6)}[/tex]

[tex]x=\frac{-12+-\sqrt{312}}{2(6)}[/tex]

[tex]x=\frac{-12+-2\sqrt{78}}{2(6)}[/tex]

Now divide each term by 12

[tex]x=-1+-\frac{\sqrt{78} }{6}[/tex]

We will get two values for x

[tex]x=-1+\frac{\sqrt{78} }{6}[/tex] and

The company's profit be if 100 games are sold is $41100

The profit function is given as:

[tex]p(x) = -0.3x^2 + 45x - 1000[/tex]

When the number of games is 100, it means that

x = 100

So, we substitute 100 for x in the profit function

[tex]p(x) = -0.3x^2 + 45x - 1000[/tex] becomes

[tex]p(100) = -0.3(100)^2 + 45(100) - 1000[/tex]

Evaluate the exponents

[tex]p(100) = -0.3(10000) + 45(100) - 1000[/tex]

Open all brackets

[tex]p(100) = -3000 + 45100 - 1000[/tex]

Answer:

John will get more money after 5 years.

Step-by-step explanation:

To calculate compound interest we use the formula

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

A = Amount

P = Principal

r = Rate of interest ( in decimal )

n = number of compounding period (quarterly = 4) (monthly = 12)

t = time in years

John wants to deposit $1000 with an interest of 4% compounded quarterly for 5 years.

[tex]A=1,000(1+\frac{0.04}{4})^{(4)(5)}[/tex]

[tex]A=1,000(1.01)^{20}[/tex]

A = 1000 ( 1.22019 )

A = $1220.19

John will get $220.19 as interest after 5 years.

Cayden wants to deposit $1,000 with an interest of 3% compounded monthly for 5 years.

[tex]A=1,000(1+\frac{0.03}{12})^{(12)(5)}[/tex]

[tex]A=1,000(1.0025)^{60}[/tex]

A = 1,000 ( 1.161617 )

A = 1161.62

Cayden will get $161.62 as interest after 5 years.

Therefore, John will get more money after 5 years.

Answer:

The probability that the candy picked is not grape flavored would be 4/5

Step-by-step explanation:

We are given that a bag contains 10 pieces of flavored candy. 4 lemon, 3 strawberry, 2 grape and 1 cherry. The probability that the candy picked is not grape flavored is calculated as;

(number of candy that are not grape flavored)/ ( total number of candy in the bag)

= (4+3+1)/(10)

= 8/10

=4/5

Therefore, the probability that the candy picked is not grape flavored would be 4/5

To find the probability that a randomly picked candy is not grape flavored, we will follow these steps:

1. Count the total number of pieces of candy in the bag. This is the sum of all the different flavors of candy:
  - 4 lemon candies
  - 3 strawberry candies
  - 2 grape candies
  - 1 cherry candy
  The total number is 4 + 3 + 2 + 1 = 10 candies.

2. Count the number of candies that are not grape flavored. Since there are 2 grape candies, the number of candies not grape flavored is the total minus the grape candies:
  10 (total candies) - 2 (grape candies) = 8 candies that are not grape flavored.

3. Calculate the probability of picking a non-grape flavored candy. Probability is the number of favorable outcomes divided by the total number of possible outcomes. In our case, the favorable outcomes are the instances where we pick a non-grape flavored candy, and the total possible outcomes are picking any candy from the bag:
  Probability (not grape flavored) = Number of non-grape flavored candies / Total number of candies
  Probability (not grape flavored) = 8 / 10

4. Simplify the fraction, if needed. In this case, the fraction 8/10 can be simplified to 4/5 by dividing both the numerator and denominator by the greatest common divisor, which is 2.

Therefore, the probability of picking a candy that is not grape flavored from the bag is 4/5, or 80% if expressed as a percentage.

X^2-4x+4 is the answer, to save you points next time, use an app called M8thw8y

First you want to drop the parenthesis. If there is a “+” sign, you do not have to change anything. If there is a “-“ sign, you have to distribute the negative in order to simplify, so imagine you are distributing -1 to 7x + 3 to make it -7x -3.

So, you now have x^2 + 3x - 4 + 16 -5 - 7x -3. (I evaluated the 4^2 to 16)

Now, what you want to do now is to combine like terms. Notice that there is only one x^2, so it is the same. There are two terms that have “x”. 3x and -7x react like normal numbers and they form -4x. The numbers who don’t have x on them you combine like terms.
