Answer:
x = 1
y = 2
Step-by-step explanation:
y = 2x
-6x + 6y = 6
-6x + 6(2x) =6 Substitute the fist equation for the value of y
-6x + 12x = 6 Combine like terms
6x = 6 divide
x = 1
Then, substitute the value of x in the equation for y
y = 2x y = 2(1)
y = 2
Answer:
0 < x ≤ 12 and 0 < y ≤ 36
Step-by-step explanation:
Here, x represents the number of female gazelles and y represents the number of male gazelles.
The zoo only has room for 12 female gazelles.
∵ The number of rooms must be more than or equal to the total female gazelles ,
12 ≥ x
Also, number of animals can not be negative,
And, it must be greater than 0.
⇒ 0 < x ≤ 12,
⇒ 3(0) < 3x ≤ 3(12)
⇒ 0 < 3x ≤ 36
∵ Number of males gazelles = 3 × number of female gazelles
⇒ y = 3x
⇒ 0 < y ≤ 36
Hence, the constraints to represent a thriving population of gazelles at the zoo are,
0 < x ≤ 12,
0 < y ≤ 36
