Answer:

Step-by-step explanation:

The equation of the line in point slope form is expressed as;

y - y0 = m(x-x0)

m is the slope

(x0, y0) is a point on the line

Get the slope;

Given the points (-1,3) and (1, 7)

m = y2-y1/x2-x1

m = 7-3/1+1

m = 4/2

m = 2

Substitute the point m = 2 and the point (-1, 3) into the formula above as shown;

y - y0 = m(x-x0)

y - 3 = 2(x-(-1))

y - 3 = 2(x+1)

Hence the required equation is y - 3 = 2(x+1)

The function can be graphed to demonstrate this further. On the graph where f(x)=0, the curve is just the x-axis, which always has the same y-value of 0.

Domaine:The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

Given the function f(x)=0,

since this is a constant function (that is, for any value of x, f(x)=0, the limit of the function as x→a, where a is any real number, is equal to 0.

More specifically, as a constant function,f(x) maintains the same value for any x. f(1)=f(2)=f(π)=f(e)=f(−(1258567)/(44))=0. Further, as a constant function, f(x) is by definition continuous throughout its domain. Note, however, that if one arrives at a constant function via division or multiplication of non-constant functions (for example, (8x)/(x), there will still exist a discontinuity where the original denominator was0).

Graphing the function will further prove this point. On the graph f(x)=0, the curve is simply the x-axis, which maintains a constant y-value of 0 no matter the x-value.

Answer:

g = 2d - 8

g + d = 46

Step-by-step explanation:

It is given that the guitarist wrote eight less than twice as many songs as the drummer did, hence one would multiply by the number of songs the drummer wrote by two, and subtract eight.

It is also given that the combined total of songs that they both wrote is 46, hence one would add up the songs that they wrote, and attain a result fo 46.

Step-by-step explanation:

250 is 125% of 200

So,

He gained 25% in profit

Based on the information given his gain as a percentage of the  cost price is 25%.

Using this formula

Cost price percentage=Selling price-Cost price/Cost price

Where:

Selling price=$250

Cost price=$200

Let plug in the formula

Cost price percentage=$250-$200/$200

Cost price percentage=$50/200

Cost price percentage=0.25×100

Cost price percentage=25%

Inconclusion his gain as a percentage of the  cost price is 25%.

Answer:

127

Step-by-step explanation:

The angles add up to 180° since they are on a straight line. Find 3x - 5.

3x - 5 + x + 1 = 180

4x - 4 = 180

4x = 180 - 4

    = 176

x = 176 ÷ 4

x = 44

3x - 5 = 3(44) - 5

Step-by-step explanation:

Explanation:

Despite there only being one line shown, there are actually two lines here. One just happens to be directly on top of the other.

We can see this by noting that 2y = 3x-1 turns into 4y = 6x-2 when we multiply both sides by 2. Multiplying both sides by the same number keeps the same equation, so that's why we have identical graphs.

The two identical graphs intersect each other infinitely many times, leading to infinitely many solutions. All solutions are (x,y) points on the blue line. Two such solutions are (1,1) and (3,4). All solutions are of the form [tex]\left(x, \frac{3x-1}{2}\right)[/tex]

The structure known as the Burj Khalifa is taller than a stack of the money it took to construct it.

The Burj Khalifa is an iconic skyscraper in Dubai, United Arab Emirates. With a height of 828 meters (2,716 ft), it is now the highest structure in the world.

The Burj Khalifa's construction began in 2004 and was finished in 2009. The skyscraper was constructed by the architectural firm Skidmore, Owings & Merrill and was mostly funded by the government of Dubai.

The Burj Khalifa stands 828 meters (2,716 ft) tall. According to sources, the overall cost of constructing the Burj Khalifa was around $1.5 billion USD. A stack of $1.5 billion USD would be roughly 165 metres (541 feet) tall if the typical US $100 bill has a thickness of 0.11 millimeters.

Therefore, the structure known as the Burj Khalifa is taller than a stack of the money it took to construct it.

Solution:

We have,

[tex]a_k=\dfrac{(-1)^k(2-k)k}{2k-1}[/tex]

Put k=k+1, to get the next term.

[tex]a_{k+1}=\dfrac{(-1)^{k+1}(2-(k+1))(k+1)}{2(k+1)-1}[/tex]

If k is even, then k+1 must be odd and odd power of -1 gives -1.

There are 6 possible outcomes: 0 points (0 questions correct), 20 points (1 question correct), 40 points (2 questions correct), 60 points (3 questions correct), 80 points (4 questions correct) and 100 points (5 questions correct). The number of points is equal to the number of questions answered times 20. The x value can only be equal to the possible number of questions answered correctly: 0, 1, 2, 3, 4, 5.

A is incorrect because it includes negative numbers and decimals. Decimal values aren't possible because no partial credit is given for the questions. Negative numbers are incorrect because you cannot answer negative questions.

Answer: 6000+240t I think

Step-by-step explanation:

A 6-sided die must be rolled 36 times before sequence 65 appears. (i.e., a 6 followed by a 5)

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

Let E as the expected rolls, and E₆ as the expected rolls given we rolled a 6.

Given that we rolled a 6, there is a 1/6 chance that two rolls will be enough, a 4/6 chance that we didn't roll a 5 or 6 and so spent two rolls, and a 1/6 chance that we rolled a 6 and only wasted one roll:

E₆ = (1/6)2 + (4/6)(E+2) + (1/6)(E₆ + 1)

Rearrange the terms and apply arithmetics operations

E₆ = (4E + 11)/5

According to the question,

We have 5/6 that we rolled [1,5]

So we wasted a roll, and 1/6 that we rolled a 6,

E = (1/6)×E₆ + (5/6)×(E+1)

Substitute the value of E₆ in the equation,

E = (1/30)×(4E+11) + (5/6)×(E+1)

E = 36

Hence, a 6-sided die must be rolled 36 times before sequence 65 appears.
