Answer:

8 family members. Average of 2.6 fish per person.

Step-by-step explanation:

How many family members caught fish? Count only those members who caught at least 1 fish (that's all of them, because nobody caught 0 fish!).

3 + 1 + 0 + 4 = 8 family members.

Average number of fish caught per person. This is the total number of fish caught divided by the total number of people.

This is a little bit tricky because, for example, 4 people caught 4 fish, making 4 x 4 = 16 fish caught.

Multiply number of fish (column 1) by the number of people (column 2):

1 x 3 + 2 x 1 + 3 x 0 + 4 x 4 = 3 + 2 + 0 + 16 = 21 fish caught.

21 fish. 8 people. On average, that is 21 / 8 = 2.625 which rounds to 2.6 fish per person.

Hint: the word "per" means divide, so "fish per person" tells you to divide the total number of fish by the total number of people.

Good Luck!

Given g(x) = <img src="https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7Bx%5E2%2B2x%7D" id="TexFormula1" title="\frac{3}{x^2+2x}" alt="\f

We know that g(x) = \frac{3}{x^2+2x}

We have to find g^-1(x) or inverse of g(x)

Inverse of g(x) can be determined by equating g(x) to y, and determining the value of x in terms of y

g(x) = y = \frac{3}{x^2+2x}

⇒ y × (x² + 2x) = 3

⇒ yx² + 2xy = 3

⇒ yx² + 2yx - 3 = 0

Determining the roots of x using:

x = $\frac{-b + \sqrt{b^{2} - 4ac}}{2a}$ OR x = $\frac{-b - \sqrt{b^{2} - 4ac}}{2a}$ , where a is coefficient of x², b is coefficient of x, and c is the constant

⇒ x = $\frac{-2y + \sqrt{4y^2 - 4(2y)(-3)}}{2y}$ OR x = $\frac{-2y - \sqrt{4y^2 - 4(2y)(-3)}}{2y}$

⇒ x = $\frac{-2y + \sqrt{4y^2 + 24y}}{2y}$ OR x = $\frac{-2y - \sqrt{4y^2 + 24y}}{2y}$

Hence, g^-1(x) = $\frac{-2y + \sqrt{4y^2 + 24y}}{2y}$ OR x = $\frac{-2y - \sqrt{4y^2 + 24y}}{2y}$

Answer:

x = 5, y = 6

Step-by-step explanation:

When you put these values in for x and y, the corresponding sides are congruent, also making the triangles congruent by the Hypotenuse-Leg Theorem.

I hope this helps! ☺
