|-6| = 6

Answer:

Step-by-step explanation:

|2x-8|=6

2x - 8 = 6

    + 8   + 8

2x = 14

/2    /2

x = 7

2x - 8 = -6

    + 8   +8

2x = 2

Answer:

The train is 0839

Step-by-step explanation:

First off, 0620 and 0746 are not available options, as Jean would've immediately know, as they're the only one with non-repeated minutes.

Now, when Marie says "I'm sure neither does Jean", it means she didn't get 06 or 07, as those are the number that has 0620 and 0746, which then she cannot ensure that Jean doesn't know the train arrival.

We're left with 0825, 0839, 0917, 0925 and 0950

After that, Jean said he knows the train number. So, he couldnt've gotten 25, as it is repeated in the 5 options we pick. => we're left with 0839, 0917 and 0950.

And then, Marie responds now she does as well, which it cannot be 09, as it is repeated.

So, the train number is 0839.

Convert fraction into negative exponential form: [tex](36^-^1)^x^-^4=(216^-^1)^x^+^1\\[/tex]

Simplify using exponent power rule: [tex](a^n)^m=a^n^m:36^-^x^+^4=216^-^x^-^1[/tex]

Convert both sides of the equation into terms with same base:[tex](6^2)^-^x^+^4=(6^3)^-^x^-^1[/tex]

Simplify using exponent power rule:

[tex](a^n)^m=a^n^m:6^-^2^x^+^8=6^-^3^x^-^3[/tex]

Based on the given conditions, corresponding exponents are equal:

Answer:

Standard form:   y = 2x² - 8x + 1

Step-by-step explanation:

We are given the following quadratic function, y = 2(x - 2)² - 7, for which we must transform in its standard form.

The vertex form of a quadratic function is y = a(x - h)² + k (which is the format of the given equation).

⇒  If the value of "a" is positive, then the vertex is its minimum or lowest point on the graph.

⇒  If the value of "a" is negative, then the vertex is the maximum or highest point  on the graph.

The standard form of a quadratic function is y = ax² + bx + c, where a ≠ 0.

The first step in rewriting the given equation into its standard form  is expanding the binomial using the FOIL method, which transforms it into a perfect square trinomial.  

y = 2(x - 2)² - 7

       ⇒   (x - 2)(x - 2)

       ⇒   [ x² - 2x - 2x + 4 ]

y = 2(x - 2)² - 7

y = 2(x² - 2x - 2x + 4) - 7

y = 2(x² - 2x - 2x + 4) - 7

y = 2x² - 4x - 4x + 8 - 7

y = 2x² - 8x + 1.

Therefore, the quadratic function in standard form is y = 2x² - 8x + 1, where a = 2, b = -8, and c = 1.

Speed is the ratio of distance and time

The elapsed time is the difference between the final time and the initial time.

So, we have:

Time elapsed = 4.5 seconds - 1.5 seconds

Evaluate the difference

Time elapsed = 3 seconds

Hence, the elapsed time is 3 s

The average speed is the quotient of the distance and the elapsed time.

So, we have:

Average speed = 4 meters/ 3 seconds

Evaluate the quotient

Average speed = 1.33 meters per second

Hence, the average speed is 1.33 m/s

Step-by-step explanation:

A single 6-pound package is approximately $5 shipping fee.

A 2-pound package is approximately $3.50 shipping fee.

A 4-pound package is approximately $4.50 shipping fee.

The question stated, "What is the approximate difference (this means we are most likely subtracting) in cost of shipping a 2-pound and a 4 pound package(the and means we are adding both 4-pound and 2-pound together) opposed to a single 6-pound package?"

As calculated above, we should add the 2-pound package and the 4-pound package together.

3.5 + 4.5 = 8

One single 6-pound package is $5, so we need to subtract the 8 with the 5.

8 - 5 = 3

Step-by-step explanation: You want to work with m variables that are the same so any item with an x is grouped together so 6x - x = 5x and the ys are grouped together 5y - 2y = 3y so your final answer would be 5x+3y

Answer:

9 units²

Step-by-step explanation:

**Refer to the attached diagram**

The angles in the right triangle FAD (and HBE) are 30-60-90 which means that its sides will be in the ratio 1 : √3 : 2

Let x = the smallest side

Therefore, the sides of the right triangle FAD are in the ratio  x : √3x : 2x

This means that:

We are told that the side length of the triangle is 3 + 2√3, so:

[tex]\implies 3 + 2\sqrt{3} =(2 + \sqrt{3} )x[/tex]

[tex]\implies x=\dfrac{3 + 2\sqrt{3}}{2 + \sqrt{3} }[/tex]

[tex]\implies x=\sqrt{3}[/tex]

As the side length of the square is √3x,  and x = √3,

⇒ side length of the square = √3 x √3 = 3

Now we know the side length of the square, we can calculate the area:

⇒ area of a square = side length x side length = 3 x 3 = 9 units²

n + c = 15

4.5n + 12c = 135

-7.5n = - 45

15n = 90

6 + c = 15

Answer:

  D  y= [x] -2

Step-by-step explanation:

The "floor" or "greatest integer" function graphs as a step function with a solid dot at the left end of each step. The point (0, 0) is one of those solid dots. When 2 is subtracted from the function value, the graph is shifted down 2 units so that it looks like the one given.

The given graph is of the equation ...

  [tex]\boxed{y=\lfloor x\rfloor -2}[/tex]

_____

Additional comment

The ceiling function ...

  [tex]y=\lceil x\rceil[/tex]

graphs as a step function with a solid dot at the right end of each step. There is a solid dot at (0, 0) for this function, as well.

Note that the function symbols have "hooks" above or below the argument to indicate ceiling or floor (respectively). The use of a square bracket [ ] for either of these functions would need to be accompanied by an explanation of the intended meaning. By itself, a square bracket has "hooks" both at the top and bottom, so does not represent either function unambiguously.

Answer:

They are not similar

Step-by-step explanation:

To see whether the triangles are similar or not we can compare their side lengths:

AB = 24

AX = 6

AX/AB = 1/4 is the ratio now let's compare this to AY/AC

AY/AC = 10/25 if we simplify this the result will be 2/5 as we can see the side lengths are not proportional so the triangles are not similar.

Renal can buy a box that is $35

Step-by-step explanation:

The inequality is 35 × 5 + 65y ≤ 500. Then the number of large gift boxes will be 5.

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.

Renaldo has a budget of $500 to buy gift boxes for a party. Large boxes cost $65 and small boxes cost $35.

Let 'x' be the number of small boxes and 'y' be the number of large boxes. Then the inequality is written as,

35x + 65y ≤ 500

If Renaldo buys 5 small gift boxes. Then the number of large gift boxes will be given as,

35 × 5 + 65y ≤ 500

175 + 65y ≤ 500

65y ≤ 325

y ≤ 5

The inequality is 35 × 5 + 65y ≤ 500. Then the number of large gift boxes will be 5.
