h(n)=

Answers

Answer:

h(n) = - 2n - 13

Step-by-step explanation:

Given

m + 1 = - 2( n + 6) = - 2n - 12 ( subtract 1 from both sides )

m = - 2n - 13, that is

h(n) = - 2n - 13

Answers

Answer:

133.33333333 percent

the diffrence is 800

Step-by-step explanation:

[(1400 - 600) / 600] × 100%

= 1.3333333333 × 100%

= 133.33333333%

Answer:

133.33% increase

Step-by-step explanation:

This is a percent increase, and to solve for one you need to know the following formula

[tex]|\frac{new~value~-~original~value}{original~value}| *100[/tex]

Plugging it in;

New value = 1400

Old value = 600

[tex]|\frac{new~value~-~original~value}{original~value}|= |\frac{1400-600}{600}| = |\frac{800}{600}| = 1.333333333[/tex]

1.3333333 as a percent is

133.33%

So you have an increase of 133.33%

How do you know whether an ecuation is an identity? How many solutions does an identity have? Explain

Choose the correct answer below

O, A. An equation is an identity w it can be rewitten as an equation of the form"variable = ruumiker, such as x=5 or y=3. Such an equation has an infinite

number of solutions because a variable can be any number

OB. An equation is an idersity it can be rewritten as an equation of the form "variable = number," such as x=5 or y=3. Such an equation has only one solution,

and the solution is called the identity of the variable

OC. An equation is an identity #it can be rewritten as 0-0. Such an equation has only one solution, 0, and that is the identity of the variable

OD. An equation is an identity if it can be rewritten as 0 =0. Such an equation has an infinite number of solutions because it reduces to a true statement

regardless of the value of the variable

Answers

Answer: D. An equation is an identity if it can be rewritten as 0 =0. Such an equation has an infinite number of solutions because it reduces to a true statement regardless of the value of the variable.

Step-by-step explanation:

For an identity equation ; The value on the right and left hand side of the equation are equal :

Left hand side = Right hand side

The solution to an identity solution is infinite because the equation holds true for every value substituted for the variable.

Hence, for every value substituted in for the variable in the equation, the equation is a true statement.

There are 80 tickets in a bag and the ratio of winning tickets to losing tickets is 2 : 8. How many of each kind of ticket are in the bag?

Answers

Given:

Total number of tickets = 80

Ratio of winning tickets to losing tickets is 2 : 8.

To find:

The number of tickets of each kind in the bag.

Solution:

Let the number of winning and losing tickets are 2x and 8x respectively.

Total number of tickets = 80

[tex]2x+8x=80[/tex]

[tex]10x=80[/tex]

Divide both sides by 10.

[tex]x=\dfrac{80}{10}[/tex]

[tex]x=8[/tex]

Now,

Winning tickets : [tex]2(8)=16[/tex]

Losing tickets : [tex]8(8)=64[/tex]

Therefore, the winning and losing tickets are 16 and 64 respectively.

Answer: 1.25 p , where  p= Weight of Jordan's dog

Step-by-step explanation:

Let p = Weight of Jordan's dog .

Given: Emmett apostrophe's dog with 25% more than Jordan star.

Then, weight (in pounds)  of Emmett apostrophe s dog  = p +25%  of p

= p +0.25 p  [We divide a number by 100 to remove %]

= p(1+0.25)

= p(1.25)

=1.25 p

Hence, the expression represents the weight in pounds of Emmett apostrophe's dog=1.25 p

A rectangular piece of metal is 9 in. longer than it is wide. Squares with sides 3 in. long are cut from the four​ corners, and the flaps are folded upward to form an open box. Which equation indicates that the volume of the box is 80 in. cubed​?

Answers

Step-by-step explanation:

Let the width be = w

The length will be = w+9

And height h = 3 inches ( side of square =3 in)

Volume = l x w x h

According to question

[tex]80 = w(w+9)3\\3w^2+27w-80=0[/tex]

So, this equation indicates that the volume of the box is 80 in.

12.718 units

Step-by-step explanation:

The coordinates of the vertices of parallelogram WXYZ are given to be W(0,-1), X(4,0), Y(3,-2) and Z(-1,-3).

So, the perimeter of the parallelogram will be 2(WX + XY) {Since opposite sides of parallelogram are same in length}

Now, length of WX =  units,  To find the units click this link :

2. Toss 4 times Imagine tossing a fair coin 4 times . (a ) Give a probability model for this chance process . (b) Define event B as getting exactly three tails . Find P(B)

Answers

Answer:

If a coin is tossed 4 times; number of possible outcomes = (2^4) = 16. 3 heads and 1 tail can occur from 4 tosses in (4C3)*(1C1) = 4*1 = 4 ways. So, the probability = (4 / 16) = (1 / 4) = 0.25.  

i didnt really understand the question but hope this helps

According to the information given, we have that:

a) A binomial model with [tex]p = 0.5[/tex] and [tex]n = 4[/tex] should be used.b) P(B) = 0.25.

For each coin, there are only two possible outcomes, either it is heads, or it is tails. The result of the flip of a coin is independent of any other flip, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

x is the number of successes. n is the number of trials. p is the probability of a success on a single trial.

Item a:

The coin is tossed 4 times, hence [tex]n = 4[/tex].It is a fair coin, hence equally as likely to be heads and tails, which means that [tex]p = 0.5[/tex].

Hence, a binomial model with [tex]p = 0.5[/tex] and [tex]n = 4[/tex] should be used.

Item b:

P(B) is P(X = 3), hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 3) = C_{4,3}.(0.5)^{3}.(0.5)^{1} = 0.25[/tex]

Hence, P(B) = 0.25.

Can anyone help me with this algebra problem ?

Answers

Answer:

a

Step-by-step explanation:

Answer:

y=mx+b is the form in which these equations are. B represents the y intercept and M is the slope

currently to find slope we need to get y alone on the left side of the equation for all the answers:

A.y-4=3(x-2) -----> y-4=3x-6 (i also distributed) ----> y=3x-2

B.  y+4=-3(x+2)----> y+4=-3x-6 -------> y=-3x-10

C. y-2=-3(x-4) --------> y-2=-3x+12 ------> y=-3x+14

D. y-4= -3( x-2) --------> y-4= -3x+6 ---------> y=-3x+10

All of these equations except A have a slope of -3 so A is already out and to find which one is valid we need to plug in the point (2, 4) for each of the equations

B. 4=-3(2)-10 ------> 4=-6-10----> 4=-16- not valid

C. 4 =-3(2)+14 ----->  4=-6+14------>4=8 not valid

D. 4=-3(2)+10 ----->4=-6+10 ------> 4=4 - Valid

Only D is correct

Answers

Answer:

543.2 miles

Step-by-step explanation:

Input the given value of x into the equation and solve for y:

y = -67.9x + 679

y = -67.9(2) + 679

y = -135.8 + 679

y = 543.2

The total distance in miles after 2 hours is 543.2 miles.
