The equation of the translated graph from the parent function is g(x) = |x + 2| + 1
How to write the equation of the translated graph?The parent function is given as
f(x)= |x|
From the graph, we can see that the parent function f(x) is translated as follows:
2 units left translation1 unit up translationThe above sequence of translation is represented as
(x, y) = (x + 2, y + 1)
So, we have

After solving the given inequality the answer is x∈(-∞, 1].
What do we mean by inequality?An inequality in mathematics is a relationship that makes a non-equal comparison between two numbers or other mathematical expressions. It is most commonly used to compare the sizes of two numbers on a number line.To solve the inequality:
Given: 2(4)x⁺³≤8
Then,
[tex]\begin{aligned}&2 \cdot 4 x^3 \leq 8\\&8 x^3 \leq 8\\&8 x^3+(-8) \leq 8+(-8)\\&8 x^3-8 \leq 8-8\\&8 x^3-8 \leq 0\\&2^3 \cdot x^3-2^3 \leq 0\\&2^3\left(\frac{2^3 \cdot x^3}{2^3}-\frac{2^3}{2^3}\right) \leq 0\\&8\left(x^3-1\right) \leq 0\\&x^3-1 \leq 0\\&x^3-1^3 \leq 0\end{aligned}[/tex]
Then,
[tex]\begin{aligned}&(x-1)\left(x^2+x+1\right) \leq 0\\&\left\{\begin{array}{l}x-1=0 \\x^2+x+1=0\end{array}\right.\\&\left\{\begin{array}{l}(x-1)+1=1 \\x_1=\frac{-1+\sqrt{1-4}}{2} \\x_2=\frac{-1-\sqrt{1-4}}{2}\end{array}\right.\\&\left\{\begin{array}{l}x-1+1=1 \\x_1=\frac{-1+\sqrt{-3}}{2} \\x_2=\frac{-1-\sqrt{-3}}{2}\end{array}\right.\\&\left\{\begin{array}{l}x=1 \\x_1=\frac{-1+\sqrt{3} \cdot \sqrt{-1}}{2} \\x_2=\frac{-1-\sqrt{3} \cdot \sqrt{-1}}{2}\end{array}\right.\end{aligned}[/tex]
So,
[tex]\begin{aligned}&\left\{\begin{array}{l}x=1 \\x_1=\frac{-1+\sqrt{3} \cdot i}{2} \\x_2=\frac{-1-\sqrt{3} \cdot i}{2}\end{array}\right.\\&\left\{\begin{array}{l}x=1 \\x_1=-\frac{1}{2}+\frac{\sqrt{3}}{2} i \\x_2=-\frac{1+\sqrt{3} \cdot i}{2}\end{array}\right.\\&\left\{\begin{array}{l}x=1 \\x_1=-\frac{1}{2}+\frac{\sqrt{3}}{2} i \\x_2=-\frac{1}{2}-\frac{\sqrt{3}}{2} i\end{array}\right.\\&\left\{\begin{array}{l}x \leq 1 \\x \geq 1\end{array}\right.\end{aligned}[/tex]
So, finally, it gives:
[tex]2 \cdot 4 x^3 \leq 8\\2 \cdot 4 \cdot 0^3 \leq 8\\\begin{aligned}&x \leq 1 \\&x \in(-\infty, 1]\end{aligned}[/tex]

A child is chosen at random from the group.

What is the probability that the chosen child is a girl?

B
What is the probability that the chosen child is a left-handed girl?
Give your answer
The probability that a girl is chosen is 1/10 and the probability that a left-handed girl is chosen is 11/20.
Probability may be defined as the possibility of occurrence of an event. Probability of an event can be 0 or 1 but it can never be negative. If probability is 0 then the event will not occur and if probability is 1 then the event will definitely occur. Probability is given by the formula.
Probability = Favorable outcomes/Total number of outcomes.
Here, total number of outcomes = 20.
Now in the first case we need to find probability of picking a girl so favorable outcome is 2.
Probability of picking a girl = 2/20
Probability of picking a girl = 1/10
In the second case we need to find probability of picking a left-handed girl, so the favorable outcomes are 2 + 9 = 11 as total number of girls are 2 and total number of left-handed people are 9.
Probability of picking left-handed girl = 9 + 2/20
Probability of picking left-handed girl = 11/20
Thus, probability that a girl is chosen is 1/10 and the probability that a left-handed girl is chosen is 11/20.

What is the quotient ∛8 x⁶ y¹² / √4 x⁴ y⁸ ?
The given quotient ( ∛8 x⁶ y¹² ) / ( √4 x⁴ y⁸ ) is x² y⁴.
This question can be easily solved by using the concept of roots. The two root terms mentioned in the question are ∛8 ( cubic root of 8 ) and √4 (square root of 4 ). This question can be solved in 4 easy steps
Determining the power of the root and find the LCM of those numbers..
In this case, the powers of root for ∛8 and √4 are 3 and 2, respectively. Take LCM of 3 and 2.
LCM = 3 x 2 = 6
=> We get the LCM of 3 and 2 as 6.
Writing the given numbers as fractional powers.
∛8 = 8¹ˡ³ => The power of 8 = 1/3
√4 = 4¹ˡ² => The power of 4 = 1/2
Step 3 : Multiply and divide the powers of the base number ( in this case 8 and 4 ) with a number such that you get the denominator as the LCM's ( in this case 6 )
1/3 can be multiplied and divided by 2 to get the denominator as 6
=> 1 * 2 / 3 * 2 = 2/6
1/2 can be multiplied and divided by 3 to get the denominator as 6
=> 1 * 3 / 2 * 3 = 3/6
Step 4 : Divide the two terms
6√8² x 6√4³ = 6√( 4 x 2 x 4 x 2 / 4 x 4 ) = 6√1 = 1
Also, x⁶ y¹² / x⁴ y⁸ = x² y⁴

Step-by-step explanation:
Gordon rolls a fair dice 162 times.
How many times would Gordon expect to roll a number greater than 3?
Answer:
81 times.
Step-by-step explanation:
A dice has 6 sides.
The dice is fair, so each side has a 1/6 chance of being rolled.
The are 3 numbers greater than 3 - 4, 5 and 6.
Each of those numbers have a 1/6 chance of being rolled.
Together, their chance of being rolled is:
1/6 + 1/6 + 1/6 = 3/6 = 1/2
The dice is rolled 162 times.
162 x 1/2 = 81
Gordon should roll a number greater than 3 81 times.

Find the inverse of each function. Is the inverse a function? g(x)=3 x³-4
Inverse of the given function F(x) = 3 x³- 4 is F⁻¹(x) = ∛[ ( y + 4 ) / 3 ]
Given is a function of x, F(x) = 3 x³- 4
These question can be solved by following 4 easy steps
Step 1 : Switch the F(x) with the variable y
This implies, F(x) = 3 x³- 4 becomes y = 3 x³- 4
Step 2 : Interchange the variable x and y in the above obtained equation
This implies, from the equation y = 3 x³- 4, we get
x = 3 y³- 4
Step 3 : Solve the new obtained equation for y
This implies, we have to simplify the equation by rearranging the terms to get the equation in terms of the variable x.
x = 3 y³- 4
=> x + 4 = 3 y³
=> 3 y³ = x + 4
=> y³ = ( x + 4 ) / 3
=> y = ∛( x + 4 ) / 3
Hence we obtain the required equation.
Step 4 : Switch the variable y with F⁻¹(x)
This implies, y = ∛( x + 4 ) / 3 becomes F⁻¹(x) = ∛( x + 4 ) / 3
Therefore, we get the inverse of the given function F(x) = 3 x³- 4 as F⁻¹(x) = ∛( x + 4 ) / 3

Solve each equation. Check for extraneous solutions. √3 x+3 -1=x
The extraneous solution for the equation √3 x + 3 - 1 = x is x = - 1 ± √ 3.
We are given an equation:

√3 x + 2 = x
Subtract 2 from both the sides, we get that:
√3 x = x - 2
Raise both sides to the power 2, we get that:

Rick paddles in still water at a rate of 6.5 mph. The rate of the current is 1.5 mph.
The rate at which an object moves from one point to another is also called speed. It can be measured by dividing the distance over time.
rate = distance/time
Let x = rate at which Rick paddles
c = rate of the current
If Rick paddles a kayak 20 miles upstream in 4 hours, and going upstream means the current is against your direction, then the equation for the travel is:
x - c = 20 miles/4 hours
x - c = 5 (equation 1)
If the return trip downstream takes him 2.5 hours, and downstream means that the current is going the same direction as you are, then the equation for the downstream travel is:
x + c = 20 miles/2.5 hours
x + c = 8 (equation 2)
Using elimination method, solve the two equations.
x + c = 8
x - c = 5
2x = 13
x = 6.5
rate at which Rick paddles = 6.5 mph
Substitute x in equation 1 and solve for c.
x - c = 5 (equation 1)
6.5 - c = 5
c = 6.5 - 5
c = 1.5
rate of the current = 1.5 mph
