Here, y = -15 with x = -20
LCM of 15 & 20 is 60, so divide 15 & 20 from 60,
60/15 = 4 & 60/20 = 3
Now, multiply the results with intial values,
4y = 3x
y = 3/4 x
When y = 12,
x = 12 * 4/3
x = 48 / 3
x = 16
In short, Your Answer would be 16
Hope this helps!
Answer:
Quartic
Step-by-step explanation:
Given

Required
Name the polynomial
The question required that the polynomial be named based on its degree.
This implies that, we name the polynomial based on the highest power of x
Highest power of x = 4
When the highest power of x in a polynomial is 4, such polynomial is a quartic polynomial.
Hence, by degree; the polynomial is quartic
The Answer Is:<span>4.222222</span>
4 2/9 = 4 + 2/9
= 4/1 + 2/9
= (4/1 * 9/9) + 2/9
= 36/9 + 2/9
= 38/9
= 38 ÷ 9 = 4.222222
