Help I dont know how to write the equation. I know its y=xb or y=x+b <br>​
34kurt

Answer:

<h2>y=x-2</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • linear equation
  • PEMDAS
<h3>given:</h3>
  • b=-2
<h3>let's solve:</h3>

the slope of the line is 1

and linear equation slope intercept form:

  • y=mx+b

therefore our equation is

  • y=x+(-2)
  • y=x-2

37. Two numbers are such that their
omeli [17]

Answer:

8 and 6

Step-by-step explanation:

Two numbers are such that their difference, their sum, and their product are to

each other as 1:7:24. Their product must equal what number?

:

Two numbers a & b

Let x = the multiplier

:

a - b = 1x

a + b = 7x

a * b = 24x

:

Add the 1st two equations

a - b = x

a + b = 7x

2a = 8x

a = 4x

or

x = .25a

:

a * b = 24x

Replace 24x; a = 4x therefore:

a * b = 6a

b = 6

;

Using the 1st equation

a - b = 1x

Replace b with 6 and x with .25a

a - 6 = .25a

a - .25a = 6

.75a = 6

a =

a = 8

:

Find the multiplier

a - b = x

8 - 6 = 2

:

Check this

a - b = 2 (1*2)

a + b = 14; (7*2)

a * b = 48: (24*2)

:

The numbers are 8 and 6; their products = 48

the total entry price of the top of the Eiffel Tower during the low season of 95 Euros for 4 students and five teachers the tota
tamaranim1 [39]

Answer:

74.30

Step-by-step explanation:

Let s = entry price for a student

Let t = entry price for a teacher

4s +5t = 95

6s+10t = 173

I will use elimination to solve this problem.

Multiply the first equation by -2

-2(4s +5t) = -2*95

Distribute

-8s - 10t = -190

Add this equation to the second equation to eliminate t

-8s - 10t = -190

6s+10t = 173

----------------------

-2s = -17

Divide by -2

-2s/-2 = -17/-2

s = 8.50

Now we need to find t

4s +5t = 95

Substitute s=8.50

4(8.50) +5(t) = 95

34 +5t = 95

Subtract 34 from each side

34-34 +5t = 95-34

5t = 61

Divide by 5

5t/5 = 61/5

t = 12.20

We want to find the cost for 3 students and 4 teachers

3s+4t

3(8.50) + 4(12.20)

25.50 + 48.80

If y=45 when x=15 find x when y=57?
Aliun [14]

Answer:

x=19

Step-by-step explanation:

To find this we need to find the simplest form of y and x

Chart:

----------------------------------------------------------------------------------------------------------------Y            | 45 |

X            | 15  |

----------------------------------------------------------------------------------------------------------------

To find the simplest form divide both sides with their gcf which is right now 15 so divide by 15: For y 15 divided by 45 is 3, for x 15 divided by 15 is one so the graph looks like this:

----------------------------------------------------------------------------------------------------------------Y            | 45 |  3  |

X            | 15  |  1  |

----------------------------------------------------------------------------------------------------------------

So now we know this fact we can just divide 57 by 3

(We need to divide it to see how many times does it take for 3 to get to 57 and we can use that number to multiply it with 1 and only one since when y is 3 x is 1.)

57 divided by 3 is 19

So we multiply 19 with 1 which is 19

So x is 19

Graph:

----------------------------------------------------------------------------------------------------------------Y            | 45 |  3  |  57  |

X            | 15  |  1  |  19   |

----------------------------------------------------------------------------------------------------------------

Hope this helps!
