#4: 4/2 reduced equals 2, so the probability of drawing a number is 2.
#2: The probability of picking a blue card would be certain because there are only blue cards in the bag.

There, I did two for ya :)

1. Certain, 1.
2. As likely as not, 1/2.
3. Impossible, 0.
4. 2/1 probability.
5. 4/1 probability.

Which equation represents f(x)?

JulijaS [17]

Function transformation involves changing the form of a function

The equation that represents the function f(x) is $f(x) = \sqrt[3] {x + 6} + 1$

<h3>How to determine the equation</h3>

The parent cube root function is:

$y = \sqrt[3] {x}$

When the function is translated 6 units left, the equation of the function becomes

$y = \sqrt[3] {x + 6}$

Next, the function is translated 1 unit up.

So, the equation of the function becomes

$y = \sqrt[3] {x + 6} + 1$

Express as a function

$f(x) = \sqrt[3] {x + 6} + 1$

Hence, the equation that represents the function f(x) is $f(x) = \sqrt[3] {x + 6} + 1$

The width of a rectangle is 6 kilometers less than twice its length. if its area is 108 square kilometers, find the dimensions

Art [367]

Hi there!

Answer:
length = 9 kilometres
Width = 12 kilometres

Let's solve this problem step by step!
To find our answer we need to set up and solve an equation.

Let the length of the rectangle be represented by x.
The width of the rectangle can therefore be expressed by 2x - 6.

The area of a rectangle can be found by using the formula:
A = width × length

Plug in the data from the formula
A = x (2x - 6).

Simplify using rainbow technique.
$x(2x - 6) = 2 {x}^{2} - 6x$

Now we've found the simplified expression that expresses the area of the rectangle. Therefore, we can now set up and start solve the equation.

$2 {x}^{2} - 6x = 108$
Subtract 108

$2 {x}^{2} - 6x - 108 = 0$
Divide by 2.

${x}^{2} - 3x - 54$
$(x - 9)(x + 6) = 0$
Rule AB = 0, gives A is 0 or B is 0.

$x - 9 = 0 \\ x = 9 \\ \\ x + 6 = 0 \\ x = - 6$

The length of the rectangle, which was represented by x, must be 9 (since it cannot be a negative number).

Length
$x = 9$
Width
$2x - 6 = 2 \times 9- 6 = 18 - 6 = 12$

Answer:
length = 9 kilometres
Width = 12 kilometres

Answer:

(5x-1)(3x+2)

(if you don't want to do all of this you can use

Step-by-step explanation:

((3•5x2) + 7x) - 2

Factoring 15x2+7x-2

The first term is, 15x2 its coefficient is 15 .

The middle term is, +7x its coefficient is 7 .

The last term, "the constant", is -2

Step-1 : Multiply the coefficient of the first term by the constant 15 • -2 = -30

Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is 7 .

-30 + 1 = -29

-15 + 2 = -13

-10 + 3 = -7

-6 + 5 = -1

-5 + 6 = 1

-3 + 10 = 7 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -3 and 10

15x2 - 3x + 10x - 2

Step-4 : Add up the first 2 terms, pulling out like factors :

3x • (5x-1)

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

2 • (5x-1)

Step-5 : Add up the four terms of step 4 :

(3x+2) • (5x-1)

Which is the desired factorization
