(9,-4) you have to plugin 9 to the equation in the form of x. Then you add 5 and that would be your y value
Answer:
There are 12 male teachers.
Step-by-step explanation:
Ratio of male teachers to female teachers in a school is 1 to 5.
For every 1 male teacher, there is one female teacher.
There are 60 female teachers.
Divide 60 by 5 = 12.
12 times 1 = 12
There are 12 male teachers.
Answer:
Step-by-step explanation:
To find Carys' earnings in one hour, fill in h=1 in the formula:
E = 10·1 = 10
Carys earns 10 dollars per hour.
__
To find the number of hours required to earn 1 dollar, fill in E=1 in the formula:
1 = 10h
0.1 = h . . . . . divide by 10
It takes 0.1 hours for Carys to earn 1 dollar.
It would take Alexandria 8 months to earn the money.
125-20= 105 monthly earnings after personal expenses
800/105= 7.6 which rounds to 8.
8x105= 840
Answer:
The largest area enclosed is A = xy = 6 feet 
6 feet = 36 
Step-by-step explanation:
i) The perimeter of the area is 2(x + y) =24 ∴ x + y = 12 ∴ y = 12 - x
ii) The area of rectangle enclosed A = xy ⇒ A = x ( 12 - x) = 12x - 
iii) differentiating both sides of the equation in ii) we get
⇒ x = 6 feet
iv) Differentiating both sides of equation in iii) we get 
= -2
Therefore the area enclosed is maximum as the double derivative is negative
v) therefore for largest area enclosed x = 6 feet and y = 12 - 6 = 6 feet
vi) therefore the largest area enclosed is
A = xy = 6 feet 6 feet = 36
