Answer:

3 min would be 30 min walking

Step-by-step explanation:

the ratio is 1 : 10

so every x the y will be 10 time x

so 4 --> 40

6 --> 60

Answer:

b) 9 + 5

Step-by-step explanation:

→ 9 - (-5)

→ [ 9 + 5 ] = 14

So, option (b) is answer.

Answer:

A: Yes, As more gallons are used the longer the shower is

B: 5 minutes, 20 minutes

C: (30,10), someone who uses 30 gallons of water will be in the shower for 10 minutes

D: I'm going to assume that your teacher wants you to find the slope in which I will use the slope formula and the points (0,0) and (30,10)

(10-0)/(30-0)=1/3=.33333 which means that for every gallon of water used you will be in the shower for .33333 minutes longer

Step-by-step explanation:

A: Yes, As more gallons are used the longer the shower is

B: 5 minutes, 20 minutes

Answer:

okay so x=-3, y=4

Step-by-step explanation:

based off the top of my head -3+5*4=17 and -4*-3=12 12+3*4=24

Answer:

x=-3 ,y=4

Step-by-step explanation:

x+5y=17------(i)

-4x+3y=24------(ii)

use substitution method

x+5y=17

make x subject of the formula

x=17-5y-----(iii)

substitute equation (iii) into equation (ii)

-4x+3y=24

-4(17-5y)+3y=24

-68+20y+3y=24

23y=24+68

23y=92

divide both sides by 23

y=92/23

y=4

substitute y in equation (iii)

x=17-5y

x=17-5(4)

x=17-20

x=-3

Answer:

the graph rises to the left and falls to the right.

the answer is B

Step-by-step explanation:

The polynomial function [tex]g(x)=-10x^7-9x^5+7x^3-8x.[/tex]. Option B is correct. When x ---> ∞ , g(x) --> -∞ and when x --> -∞, g(x) --> ∞ .

Given that,
polynomial function [tex]g(x)=-10x^7-9x^5+7x^3-8x.[/tex]

A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.

The Range, it is the set of the values that come out to an outcome for a certain mathematical operation.

Since, In the question, polynomial function [tex]g(x)=-10x^7-9x^5+7x^3-8x[/tex] is given,
When the value of x = (0, +∞)
           range of g(x) = (0, -∞)
Whn the value of x = (0, -∞)

             range of g(x) = (0, +∞).

Thus, the polynomial function [tex]g(x)=-10x^7-9x^5+7x^3-8x.[/tex]. Option B is correct. When x ---> ∞ , g(x) --> -∞ and when x --> -∞, g(x) --> ∞ .

Answer:

Its actually C

Step-by-step explanation:

|So you first divide 29 from 40. You will need to long divide...because 40 cant go into 29. you will put a 0 on the top then you will put a decimal behind the 0 representing your going into the tenths, and then from there you just divide like you usually do.

Hope you get it, if you need more explanation please tell me :)

Answer:

188.27

Step-by-step explanation:

divide the starting number (1500) by 100 to get 1% then times by 3 to get the new number for tje start of tje next year.

After 1st- 1545

after 2nd year = 1591.35

After 3rd = 1639.1005

After 4th= 1688.273515

what he gained is 1688.273515-1500= 188.273515.

now round to 2 decimals = 188.27

Answer:

26% probability that a 1 was received.

Step-by-step explanation:

We have these following probabilities:

70% probability that a message is transmitted as a 0.

100 - 70 = 30% probability that a message is transmitted as a 1.

If a message is transmitted as a 0, 95% probability of being received as a 0 and 5% probability of being received as 1.

If a message is transmitted as a 1, 75% of being received as a 1 and 25% probability of being received as a 0.

If a signal is sent, determine the probability that a 1 was received.

5% of 70%(Sent 0, received 1) of 75% of 30%(sent 1 and received 1). So

[tex]p = 0.05*0.7 + 0.75*0.3 = 0.26[/tex]

26% probability that a 1 was received.
