which graph represents the solution to the system of linear inequalities x>3 and y < or equal to 2

The set is linearly dependent.

To explicitly prove this, we need to show there is at least one choice of constants [tex]c_1,c_2,c_3,c_3\in\Bbb R[/tex] such that

[tex]c_1 u + c_2 v + c_3(v-w) + c_4(u+v+w) = 0[/tex]

or equivalently,

[tex](c_1 + c_4) u + (c_2 + c_3 + c_4) v + (-c_3 + c_4) w = 0[/tex]

which is the same as solving the system of equations

[tex]\begin{cases} c_1 + c_4 = 0 \\ c_2 + c_3 + c_4 = 0 \\ -c_3 + c_4 = 0 \end{cases}[/tex]

From the first and last equations, we have [tex]c_1=-c_4[/tex] and [tex]c_3=c_4[/tex]. Substituting these into the second equation leaves us with [tex]c_2-2c_1=0[/tex], and so the overall solution set is

[tex]c_1 = \dfrac12 c_2 = -c_3 = -c_4[/tex]

for which there are infinitely many not-all-zero solutions.

Complete question is:

The function f(x) = 600 - 100x models the value, f(x), of a video game system x years after purchase. Which choice represents the most appropriate domain of the function?

Answer and explanation:

The domain of a function is the values you can plug into the function, the possible values for x.

While x could take any value, there are a range of apropiate values that it can take.

For example, since x represents years after purchase, x can not be a negative number, because that would represent negative years, thus x must be greater or equal to 0.

After solving basic fractions we have come to find that, we need 12.7 tiles to create a frieze above a Forrest.

When describing a portion or part of a whole in mathematics, a fraction is used. The equal components of the whole are represented by it. Both the numerator and denominator are components of a fraction.

Both the top and bottom numbers are referred to as the numerator and denominator, respectively. The denominator specifies the total number of equally sized pieces in the whole, whereas the numerator specifies the number of equal parts that were taken.

A fraction is something like 5/10.

The denominator in this case is 10, and the numerator is 5.

The measure of each tile = 2⅞

                                          = 23/8

Measure of doorway = 36½

                                   =  73/2

No. of tiles we need = 36½ /  2⅞

                                  = 12.7 tiles

Thus, we need 12.7 tiles to create a frieze above a Forrest.

The correct answer is: " 9 " .
_______

Step-by-step explanation:

Given:  " x³ +  x⁰ " ;  Evaluate for "x = 2 ".

Plug in 2 for the x values; and solve:
  " 2³ + 2⁰ " ;
Note:  " 2³ = 2 * 2 * 2 = 8 " ;

           " 2⁰ = 1 " .

Note: Any 'non-zero' value, raised to the 'zeroth' [0°]' exponential power, is equal to 'one' [ 1 ].

So: " x³ + x⁰ =  2³ + 2⁰ = 8 + 1 = 9 ."

The answer is:  " 9 ".

The image of the point P(x, y) = (4, 2) by means of a translation formula is point P'(x, y) = (- 1, 4).

In this question we find the coordinates of a point set on Cartesian plane which is modified by using a translation, a kind of rigid transformation. Rigid transformations are transformations applied on geometric loci such that Euclidean distances are conserved.

Vectorially speaking, translations are described by the following formula:

P'(x, y) = P(x, y) + T(x, y)

Where:

If we know that P(x, y) = (- 9, - 3) and P'(x, y) = (- 14, - 1), then the translation vector is:

T(x, y) = P'(x, y) - P(x, y)

T(x, y) = (- 14, - 1) - (- 9, - 3)

T(x, y) = (- 5, 2)

Then, the image of the point (4, 2) is:

P'(x, y) = (4, 2) + (- 5, 2)

P'(x, y) = (- 1, 4)

The image of the point (4, 2) by using a translation formula is (- 1, 4).

Answer:

D. 1/4

Explanation:

By definition, two lines are parallel if they have the same slope.

Given that lines a and b are parallel; and the slope of line a = 1/4, then:

The slope of line b = 1/4.

The correct choice is D.

The slope is calculated by findidng the ratio of the vertical change (change in y) to the horizontal change (change in x) between any two distinct points.

Then the slope formula is:

Part A: -5/9, 6/10, -7/11, 8/12

Part B:

Part C: Positive

The given sequence is:

As seen above the sequence is an alternating sequence because it changes in sign

Also, neglecting the sign chnages, we will observe, a common diffference of 1 in the numerator and denominator

a) Therefore, if the pattern continues, the next 4 terms in the sequence are:

-5/9, 6/10, -7/11, 8/12

b)

Without the sign, the explicit equation representing the numerator is calculated below:

1, 2, 3, 4......

The first term, a = 1

The common difference, d = 1

This is an arithmetic sequence

N(n) = a + (n - 1)d

N(n) = 1 + (n - 1)(1)

N(n) = 1 + n - 1

N(n) = n

The explicit equation representing the denominator is calculated below

5, 6, 7, 8........

The first term, a = 5

The common difference, d = 1

D(n) = a + (n - 1)d

D(n) = 5 + (n - 1)(1)

D(n) = 5 + n - 1

D(n) = n + 4

The alternating sequence will include the term below:

Therefore, the explicit equation for f(n) representing the sequence is:

Part C) The sign of f(56) will be:

(-1)^56 = 1

Since this gives us a positive value, the sign of f(56) is positive

Answer:

10.59480821 hours

Step-by-step explanation:

2. Now we know the percent for each surface

3. Now that we know the percent of each surface we need to find out how many km for each surface:

Uphill

Downhill

Flat

3. Now that we know all the percent and distance for each surface we need to know the km/h for each

Uphill = 24.25km/h

Downhill = x

Flat = 55.5km/h

4. Since we don't have the speed for downhill we need to know the difference between uphill and flat

5. Now we know the difference is 31.25 we can add that to the flat surface to get the downhill speed

6. Now we know all the speeds and now we can figure out how many hours it takes for each surface

( we are going to take the distance in 1 surface and then divide that by the km/h in that surface to ket how many hours)

Uphill

Downhill

Flat

7. Now we add all the hours up

6 is adding on the right, then it will subtract on the left

4 is dividing on the right, then it will multiply on the left

Number of step = 52

The radius of the circle is 6.48 in.

To find:

We need to find the arc length of RS.

Explanation:

Consider the formula to find the length of the arc.

The true statement is g(-13)= 20.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. Mapping or transformation is used to denote a function in math. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

domain = -20 ≤ x ≤ 5

and a range = -5 ≤ g(x) ≤ 45

and g(0) = -2 and g(-9) = 6

First, g(-13)= 20

x=-13 is in our domain  and 20 is also in our range .

So this is true for g(-13)= 20.

Now, g(-4) = -11

-11 does not comes under the range.

So this statement is not true.

Again,  g(0) = 2 is false because  g(0) = - 2.

and,  g(7) = -1 D

7 is not in our domain .

So g(7) is not possible
