Answer: x=10

Step-by-step explanation:

f(x)=2 is the same things as y=2. Since we know that y=2, you can plug that in to solve for x.

y=\frac{x+6}{x-2}                    [plug in y=2]

2=\frac{x+6}{x-2}                    [multiply both sides by x-2]

(x-2)2=x+6       [distribute]

2x-4=x+6          [subtract both sides by x]

x-4=6                  [add both sides by 4]

x=10

Now after we have plugged in y=2, we know that x=10.

Select the list that correctly includes all of the coefficients from the problem
matrenka [14]

Answer:

( B.) 6, 1, -2 , -4

Step-by-step explanation:

A coefficient is a number multiplied by a variable. So, in this case let's take a look at the problem.

-2+6y+m-2y+8-4m

Now we have to find the numbers that have a variable next to it

which are 6,m,-2, and -4

(If you are wondering that why m is a coefficient its because it is also known as 1m)

Final answer = 6, 1, -2 , -4

Hope this helps!

A BbGg x bbgg cross yields a phenotypic ratio of approximately 5 black eyes, green skin : 5 orange eyes, white skin : 1 black ey
Nostrana [21]

Answer:

The explanation for this result is that: The probability of expressing the black eye and the white skin together is 1/6 also of expressing the orange eyes with the green skin at the same time on the same organism is also 1/6.

Step-by-step explanation:

From the result, it can be inferred that the Black eye is controlled majorly by the dominant homozygous BB gene, the green skin by heterozygous Gg gene, the orange eye is controlled by the homozygous recessive bb gene, while the white skin by the recessive homozygous gg gene.

The genotypic ratio of the cross is: 1 BBGg, 1 Bbgg, 1 bbGg, 1 bbgg.

If 1 BbGg represents the 5 black eyes, green skin,

1 bbgg represents the 5 orange eyes, white skin,

1 Bbgg represents the 1 black eyes, white skin, and

1 bbGg represents the 1 orange eyes, green skin. It seems to have the same chance of expression, but this result showed us that when the black eye and the white skin are together, they tend to inhibit their expression, so they have little chance of 1 of 6.
