Answer:

Answer is given below. If you have any doubts write in comments box. 

Step-by-step explanation:

$y = - 3 x - 2 \\ when \: x = - 1 \: \\ - 3( - 1) - 2 = 3 - 2 = 1 \\ when \: x \: = 0 \\ - 3(0) - 2 = 0 - 2 = - 2 \\ when \: x \: = 1 \\ - 3(1) - 2 = - 3 - 2 = - 5 \: \\ \\ therefore \: ordered \: pair \: is \:( - 1,1)(0, - 2)(1, - 5)$

 HAVE A NICE DAY!

11. Let the Number of Students filled in One Van be : V

Let the Number of Students filled in One Bus be : B

Given : The Senior Class of High School A rented and filled 8 Vans and 3 Buses with 150 students

⇒ 8V + 3B = 150 --------------- [1]

Given : The Senior Class of High School B rented and filled 10 Vans and 3 Buses with 162 students

⇒ 10V + 3B = 162 --------------- [2]

Subtracting Equation [1] from Equation [2], we get :

⇒ (10V + 3B) - (8V + 3B) = 162 - 150

⇒ 10V - 8V + 3B - 3B = 12

⇒ 2V = 12

⇒ V = 6

Substituting V = 6 in Equation [1], We get :

⇒ 8(6) + 3B = 150

⇒ 48 + 3B = 150

⇒ 3B = 150 - 48

⇒ 3B = 102

⇒ B = 34

⇒ Each Van can carry 6 Students

⇒ Each Bus can carry 34 students

12 . Let the Price of One Adult Ticket be : A

Let the Price of One Student Ticket be : S

Given : On the First Day, The School sold 6 Adult tickets and 7 student tickets for a Total of $122

⇒ 6A + 7S = 122 ----------- [1]

Given : On the Second Day, The School sold 6 Adult tickets and 6 student tickets for a Total of $114

⇒ 6A + 6S = 114 ----------- [2]

Subtracting Equation [2} from Equation [1], We get :

⇒ (6A + 7S) - (6A + 6S) = 122 - 114

⇒ 6A - 6A + 7S - 6S = 8

⇒ S = 8

Substituting S = 8 in Equation [1], We get :

⇒ 6A + 7(8) = 122

⇒ 6A + 56 = 122

⇒ 6A = 122 - 56

⇒ 6A = 66

⇒ A = 11

⇒ Price of One Adult Ticket = $11

⇒ Price of One Student Ticket = $8

Combine like terms:

pickupchik [31]

So we have to use the distributive property:

We ll get -12x-9-2x+5+18x-24
Now we have to combine like terms
-12-2x+18x=4x
-9+5-24=-28
Therefore our answer is:
Y=4x-28

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit

AleksandrR [38]

2x + 3y = 1470
3y = -2x + 1470
y = -2/3x + 490 <== slope intercept form
=================
y = -2/3x + 490
slope = -2/3
y int = (0,490)
=================
description of graphing : Plot ur point at (0,490). Since the slope is -2/3, starting at (0,490)...go down 2 and to the right 3,then down 2 and to the right 3 and you will eventually cross the x axis at the x intercept.

The x intercept can be found by subbing in 0 for y and solving for x
y = -2/3x + 490
0 = -2/3x + 490
2/3x = 490
x = 490 * 3/2
x = 1470/2 = 735...so ur x intercept is (735,0)

therefore, your line will cross the x axis at (735,0)
========================
function notation is : f(x) = -2/3x + 490
========================
suppose his profit is 1593....
2x + 3y = 1593
3y = -2x + 1593
y = -2/3x + 531

the graphs for the two months :
similarities : they both have the same slope of -2/3
differences : they have different x and y intercepts
By the way, these are parallel lines
===================
sorry about the last one....can't see the 3rd month graph
