We know that
the equation of a line in <span>slope intercept form is--------------> y=mx+b
where
m-----------> is the slope
b-----------> is the y-intercept  point when x=0

</span><span>y+7=-1/7(x+4)---------> y+7=(-1/7)x-4/7
</span>y+7=(-1/7)x-4/7------> y=(-1/7)x-4/7-7------> y=(-1/7)x-(53/7)

the answer is
y=(-1/7)x-(53/7)-------------> this is the equation of a line in slope intercept form
m=(-1/7)=-0.14
b=(-53/7)=-7.57
y=-0.14x-7.57

see the attached figure

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

The original rectangle has a perimeter of 16
svet-max [94.6K]

12.4 / 6.2 = 2

so other side of enlarged rectangle = 1.8 x 2 = 3.6

Perimeter of enlarged rectangle = 2(3.6 + 12.4) = 32

Answer: 32 feet

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

Another way to do:

12.4 / 6.2 = 2

SF = 2

The original rectangle has a perimeter of 16

Perimeter of the enlarged rectangle = 16 x 2 = 32

Answer: 32 feet
