If i had a dozen eggs and i dropped 2/3 how many eggs did i dropped

Semenov [28]

You can divide 12 by 3 to make it equivalent to 1/3 of the equation. This will come to 4, which will then be multiplied by two to get you the answer of 8.

Hope this helps! <3

2. Solve the following inequality -1 >-2(x-4) - 5(4x - 7).

Marta_Voda [28]

x<2

Step-by-step explanation:

-1>-2(x-4)-5(4x-7)

-1>-2x+8-20x+35

-1>-22x+43

when a negative number crosses to a side, the sign changes

22x<1+43

22x<44

22x/22<44/22

x<2

A 100-gallon fish tank fills at a rate of x gallons per minute. The tank has already been filling for 5 minutes. The function

kykrilka [37]

Answer:

- Stretching the parent function $f(x) =\frac{1}{x}$ vertically .

- Shifting the parent function $f(x) =\frac{1}{x}$ 5 units right.

Step-by-step explanation:

<h3>The complete exercise is: " A 100 gallon fish tank fills at a rate of x gallons per minute. The tank has already been filling for 5 minutes. The function $f(x) = \frac{100}{x -5}$ represents the remaining time in minutes needed to fill the tank. How is the graph of the parent function $f(x) =\frac{1}{x}$ transformed to create the graph of $f(x) = \frac{100}{x -5}$ ?"</h3><h3 />

Below are some transformations for a function :

1. If $f(x)+k$ , the function is shifted "k" units up.

2. If $f(x)-k$ , the function is shifted "k" units down.

3. If $f(x)-k$ , the function is shifted "k" units right.

4. If $f(x)+k$ , the function is shifted "k" units left.

5. If $bf(x)$ and $b>1$ the function is stretched vertically by a factor of "b".

6. If $bf(x)$ and $0$ the function is compressed vertically by a factor of "b".

The exercise gives the following parent function:

$f(x) =\frac{1}{x}$

And you know that the transformed function which represents the remaining time in minutes needed to fill the tank, is:

$f(x) = \frac{100}{x -5}$

Therefore, based on the transformations explained before you can identify that the graph of the transformed function is created by:

- Stretching the parent function $f(x) =\frac{1}{x}$ vertically.

- Shifting the parent function $f(x) =\frac{1}{x}$ 5 units right.

Devide (a2+ 7a+ 12)÷ (a+3)

arlik [135]

Answer:

(a - 3) • (a - 4)

Step-by-step explanation:

The first term is, a2 its coefficient is 1 .

The middle term is, -7a its coefficient is -7 .

The last term, "the constant", is +12

Multiply the coefficient of the first term by the constant 1 • 12 = 12

Find two factors of 12 whose sum equals the coefficient of the middle term, which is -7 .

-12 + -1 = -13

-6 + -2 = -8

-4 + -3 = -7 That's it

Rewrite the polynomial splitting the middle term using the two factors, -4 and -3

a2 - 4a - 3a - 12

Add up the first 2 terms, pulling out like factors :

a • (a-4)

Add up the last 2 terms, pulling out common factors :

3 • (a-4)

Add up the four terms

(a-3) • (a-4)

Really hope this helps :)
