Answer:

yes

Step-by-step explanation:

Substitute x = 2 and y = 2 into both equations and if both are true then (2, 2) is a solution of the system.

y = x, that is

2 = 2 ← True

x + 2y = 6, that is

2 + 2(2) = 2 + 4 = 6 ← True

Thus (2, 2) is a solution of the system

How can you show that two objects are proportional with a table?
vredina [299]
So this is our table:

               -----------------
x-values | a b c d e f  |
               -----------------
y-values | g h  i  j k l   |
               -----------------

You can know that the values in the table are proportional if:

\frac{a}{g}=\frac{b}{h} =\frac{c}{i}=\frac{d}{j}=\frac{e}{k}=\frac{f}{l}

Hope that helps :)

Unattached earlobes are a dominant trait in humans. finn and maggie both have unattached earlobes but their daughter, celia, doe
11111nata11111 [884]
The answer is 1/4.

The genes when combined must be Heterozygous, meaning they have one dominant and one recessive, Celia must have gotten the 1/4 recessive, and it won't change the way genetics are just because you've already had offspring, the percentage stays the same.
