Answer:

-2

Step-by-step explanation:

We use the slope formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], and substitute the points (0,8) and (2,4). This gives

[tex]\frac{4-8}{2-0}=\frac{-4}{2}=-2[/tex]

as the slope.

Hello.

Since we have two points, and we are asked to find the slope of the line, let's use the slope formula:

[tex]\mathrm{m=\displaystyle\frac{y2-y1}{x2-x1}}[/tex]

Where

m is the slope

y2 is the y-coordinate of the second point

y1 is the y-coordinate of the first point

x2 is the x-coordinate of the second point

x1 is the x-coordinate of the first point

In this case, m is unknown, y2 = 4, y1 = 8, x2=2, x1=0

Plug in the values:

[tex]\displaystyle\frac{4-8}{2-0}[/tex]

[tex]\displaystyle\frac{-4}{2} =-2[/tex]

Therefore, the slope is -2.

I hope it helps!

Have a nice day!

Answer:

First choice

Step-by-step explanation:

It passes through (4, 0) and (0, -4)

Slope = (0 - (-4))/(4 - 0) = 4/4 = 1

so y - 0 = 1*(x - 4)

x - y = 4

8x - 8y = 32

Step-by-step explanation:

Assets are the economic resources belonging to a business. Assets could be money in a cash register or bank account, or items such as property, fixtures and furniture, equipment, motor vehicles, and stock or goods for resale. An important asset in businesses which sell goods or services on credit is money owed to the enterprise by customers. This asset is known as debtors.

Capital is the value of the investment in the business by the owner(s). It is that part of the business that belongs to the owner; hence it is often described as the owner’s interest.

Liabilities are the debts owed by the firm. The main types of liabilities are creditors (money owed by the business to suppliers of goods and services), bank overdrafts and bank loans.

Step-by-step explanation:

she drove already 165 miles.

she will reach her destination, if she drives 4 more hours by going 65 miles/hour.

that would mean she would travel

65×4 = 260 miles

in these 4 hours.

so, the total trip is then 165 + 260 = 425 miles.

but what I find strange is that your teacher specified how long it took her to drive the first 165 miles.

as you can see above, it would make no difference for the calculation of the total trip length in miles.

this is either an attempt to confuse us, or the message is that Judy has to achieve an average of 65 miles/hour for the whole trip, and the problem definition was just imperfectly phrased.

if that is the case, then things look a bit different, as her average speed was only 165/3 = 55 miles/hour for the first 3 hours and 165 miles.

so,

(165 + x)/(3 + 4) hours = 65/hour

(165 + x)/7 hours = 65/hour

165 + x = 65 × 7 hours / hour = 65×7 = 455 miles

x = 455 - 165 = 290 miles

she would have to go

290 miles / 4 hours = 72.5 miles/hour

for these next 4 hours (and 290 miles) to reach an overall average speed of 65 miles/hour.

and the total trip would be then

165 + 290 = 455 miles

I am not sure, which your teacher wants here.

65 miles/hour average speed just for the next 4 hours, or to speed up that much for the next 4 hours that the overall trip average is then 65 miles/hour.

again, the phrasing of the problem definition suggests the first case, but the fact that the travel time for the first part of the trip is given could suggest the second case (as this information is not needed for the first case).

The amount the customers pay is an illustration of a piecewise functions

The equations of the piecewise functions are: [tex]y = \left[\begin{array}{cc}5x&0 < x \le 5\\4x&x > 5\end{array}\right[/tex]

For the first function, we have the following points.

(x,y) = (0,0) and (4,20) for 0 < x <= 5

Since the line passes through the origin, the equation of the line would be:

[tex]y = \frac{y_1}{x_1} * x[/tex]

So, we have:

[tex]y = \frac{20}{4} * x[/tex]

[tex]y = 5x[/tex]   0 < x <= 5

For the second function, we have the following points

(x,y) = (8,32) and (9,36) for x > 5

The equation of the line would be:

[tex]y = \frac{y_1-y_2}{x_1-x_2} * (x - x_1) + y_1[/tex]

So, we have:

[tex]y = \frac{36-32}{9-8} * (x - 8) + 32[/tex]

[tex]y = 4(x - 8) + 32[/tex]

[tex]y = 4x - 32 + 32[/tex]

[tex]y = 4x[/tex]    x > 5

Hence, the equations of the piecewise functions are:

[tex]y = \left[\begin{array}{cc}5x&0 < x \le 5\\4x&x > 5\end{array}\right[/tex]

Answer:

Step-by-step explanation:

The fraction of his lotto earnings that is remaining is 7/20.

A fraction is a portion of a whole or, more broadly, a set of equal pieces.

Let the total amount that the man won in the lotto jackpot is x.

Now, he spent 2/5 of the jackpot on luxury cars and 1/4 on buying a house, therefore, the total spending he will do is,

[tex]\dfrac{2x}{5}+\dfrac{x}{4}[/tex]

Now, the fraction of his lotto earnings that is remaining can be written as,

[tex]x-\dfrac{2x}{5}+\dfrac{x}{4}\\\\\\=\dfrac{x}{1}-\dfrac{2x}{5}-\dfrac{x}{4}\\\\\\=\dfrac{x \times 20}{1 \times 20}-\dfrac{2x \times 4}{5 \times 4}-\dfrac{x\times 5}{4\times 5}\\\\\\=\dfrac{20x-8x-5x}{20}\\\\=\dfrac{7x}{20}[/tex]

Hence, the fraction of his lotto earnings that is remaining is 7/20.

Step-by-step explanation:

P(7,r) = 5040

[tex]P(n,r)=\dfrac{n!}{(n - r)!}\\\\\\n = 7 \\\\\dfrac{7!}{(7 - r)!}=5040\\\\\\7! = (7-r)!*5040\\\\(7-r)!=\dfrac{5040}{7*6*5*4*3*2*1}\\\\\\(7-r)!=\dfrac{5040}{5040}\\\\\\(7-r)!=1\\\\[/tex]

Answer:

  12.  B or C

  13.  C

  14.  A

  15.  A

Step-by-step explanation:

These problems involve various counting techniques. For combinations and permutations, there are formulas to aid in the counting. For other situations, you may need to list possibilities.

__

  P(7, r) = 5040 . . . . . given

  P(7, r) = 7!/(7 -r)! = 5040

  5040/(7 -r)! = 5040 . . . . . evaluate 7!

  (7 -r)! = 1 . . . . . . . . . . . multiply by (7-r)!/5040

We know that both 0! and 1! = 1, so this has two solutions:

  7 -r = 0   ⇒   r = 7

  7 -r = 1   ⇒   r = 6

Both choices B and C are correct.

The attached calculator output confirms this result.

The formula of choice C is correct:

  C(n, r) = n!/((n-r)!r!)

The number of permutations of the 9 letters is reduced by the numbers of permutations of letters that are indistinguishable. That is, the 9 letters can be rearranged 9! ways, but the 4 Es are indistinguishable, so a factor of 4! must be removed from that result. Similarly, the two Ns and two Ss are indistinguishable, so additional factors of 2! must be removed. The number of arrangements is ...

  9!/(4!2!2!) . . . . matches choice A

__

The 5 students can be arranged in 5 consecutive chairs in P(5, 5) = 5! = 120 ways. Those 5 consecutive chairs can start in chairs 1 through 6, so there are 6×120 = 720 ways the 5 students can sit together in 10 chairs.

Answer: 7:3 and 28:12

Step-by-step explanation:

The equivalent form of the given ratio is 7 : 3. The correct answer is option (b).

A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

The given ratio is 14 : 6.

A ratio of two numbers a and b can be written in the form of fraction as,

a : b = a/b

Thus, the given ratio can be simplified as,

14 : 6 = 14/6

         = 7/3

Again it can be converted into the ratio as,

7/3 = 7 : 3

Hence, the equivalent ratio of the given ratio is 7 : 3.

Step-by-step explanation:

If this were to make a triangle, then 30.1 and 0.8 would be the shorter sides and 31 would be the longest side.

The sum of the lengths of the shorter sides is 30.1+0

8=30.9.

Since this is less than the length of the segment that would be the longest side, by the triangle inequality theorem, these side lengths would not make a triangle.
