Answer:
x = 4; y = 8
Step-by-step explanation:
y=2x
y=x+4
2x = x + 4
x = 4
y = 2x = 2(4)
y = 8
Solution: x = 4; y = 8
The percentage of the offspring that will have atatched earlobes as the dominant trait, is: 50%.
What is a Dominant Trait?
A dominant trait surpresses a recessive trait, and expresses itself. The allele of a dominant trait is usally denoted using capital letters.
Given the following traits:
A - attached earlobes (dominant allele)
a - unattached earlobes (recessive allele)
A cross between Aa and aa is shown in the image attached below.
The offspring having attached earlobes = 2 Aa = 50%.
50% of the osspring will have attached earlobes.

are 2 and 
Answer:
4092
Step-by-step explanation:
r = 2
a1 = 4×(2)^(1 - 1) = 4
S10 = a1×((1 - r^10)/(1 - r)
= 4×((1 - 2^10)/(1 - 2))
= 4×((1 - 2^10)/-1)
= 4×(-(1 - 2^10))
= -4×(1 - 2^10)
= -4 + 4 × 2^10
= -4 + 2^2 × 2^10
= -4 + 2^12
= -4 + 4096
= 4092
