Example Question: 6x + 4 = 22
The goal in this is to get the variable alone and these are the steps how to. What you have to do is subtract 4 from 4 so that you can get 6x alone. But when you subtract 4 from one side, you have to subtract 4 from the other side too which leaves us with 6x = 18. Now, we have to do the opposite of multiplication which is division. So we are going to do 6x divided by 6 and the two sixes cancel each other out. But remember, if you do something to one side you have to do it to the other as well. So we have to do 18/6 which leaves us with the answer.

Choose the correct transformation of the graph f(x) = |x + 8| - 3.
The graph of f(x) = x| is shifted to the left 8 units, down 3 units.
The graph of f(x) = x| is shifted to the right 8 units, down 3 units.
The graph of f(x) = x| is shifted to the left 8 units, up 3 units.
The graph of f(x) = x| is shifted to the right 8 units, up 3 units.
Answer:
A. The graph of f(x) = |x| is shifted to the left 8 units, down 3 units.
Step-by-step explanation:
We are given,
The transformed function is [tex]f(x)=|x+8|-3[/tex].
Now, the parent function is [tex]f(x)=|x|[/tex].
So, we have,
When the parent function is shifted 8 units to the left, the function is [tex]|x+8|[/tex].
This function when translated 3 units downwards gives [tex]f(x)=|x+8|-3[/tex].
Thus, we get,
The parent function f(x)=|x| is translated 8 units to the left and 3 units downwards.So, option A is correct.

Is it possible to remove ten unit cubes from a 3 by 3 by 3 cube made from 27 unit cubes so that the surface area of the remaining solid is the same as the surface area of the original 3 by 3 by 3 cube? In how many different ways can this be done?
I removed all eight corners, leaving the total area unchanged.
I removed the central cube of the top surface obtaining an increase of the surface area with four units.
I removed one cube from the middle of an edge at the top (any of the four remaining) and I arrived at a figure with ten cubes less then the original one but with the same surface area.
https://nrich.maths.org/787/solutionThe cube can be removed from the top middle and from the center if a 3 by 3 by 3 cube is made from 27 unit cubes.
What is surface area?An object's surface area refers to the overall space that its surfaces occupy.
Given:
The dimensions of the cube are 3 by 3 by 3
Calculate the surface area of the cube as shown below,
Surface area = 6 × side²
Surface area = 6 × 3²
Surface area = 6 × 9
Surface area = 54
I eliminated each of the eight corners, leaving the entire space untouched.
I deleted the top surface's central cube to increase the surface area by four units.
I started with a shape that was ten cubes smaller than the original one but had the same surface area after removing one cube from the center of one of the top edges (any of the four still there).

This figure shows the nose cone of a rocket used for launching satellites. The nose cone houses the satellite until the satellite is placed in orbit. What is the volume of the nose cone?
45 cubic feet
60 cubic feet
90 cubic feet
180 cubic feet
Thank you :)
Answer:
[tex]45\pi\ ft^3[/tex]
Step-by-step explanation:
The volume of the cone can be calculated using formula
[tex]V_{cone}=\dfrac{1}{3}\cdot \pi r^2\cdot H,[/tex]
where [tex]r[/tex] is the radius of the base circle and [tex]H[/tex] is the height of the cone.
Since [tex]r=3\ ft[/tex] (half of the diameter given in the diagram) and [tex]H=15\ ft,[/tex] then
[tex]V_{cone}=\dfrac{1}{3}\cdot \pi \cdot 3^2\cdot 15=45\pi\ ft^3.[/tex]

What is the missing term? (10x-4x^2)-(7x+?)=3x-6x^2
The given problem is =
[tex]( 10x-4x^{2} )-(7x+?)=3x-6x^{2}[/tex]
Lets suppose the missing term to be T
So equation becomes:
[tex]10x-4x^{2} -7x-T=3x-6x^{2}[/tex]
[tex]T=10x-4x^{2} -7x-3x+6x^{2}[/tex]
[tex]T=2x^{2}[/tex]
Hence, the missing term is [tex]2x^{2}[/tex]

How many subsets of exactly two elements does a set of five elements have?
A.10
B.26
C.7
D.32
Option: A is the correct answer.
A. 10
Step-by-step explanation:We know that the number of subsets of exactly ''r'' elements that is formed by the help of n elements is calculated by:
[tex]n_C_r[/tex]
Since here we have to chose 2 elements out of the 5 elements in order to form a subset.
Hence, we have: n=5 and r=2
Hence, the number of subsets are:
[tex]5_C_2=\dfrac{5!}{2!\times (5-2)!}\\\\\\5_C_2=\dfrac{5!}{3!\times 2!}\\\\\\5_C_2=10[/tex]
Hence, the number of subsets are:
10

Which number can each term of the equation be multiplied by to eliminate the decimals before solving? –m + 0.02 + 2.1m = –1.45 – 4.81m A)0.01
B)0.1
C)10
D)100
since the 2 in 0.02 is in the hundredths place, you need to multiply that by 100 to eliminate the decimal, then you would need to multiply the other numbers by 100 as well
Answer is D) 100
The decimals place in a number can be shifted right or left by multiplying or dividing by powers of 10 respectively
The option which gives the number that will multiply each term of the equation -m + 0.02 + 2.1·m = -1.45 - 4.81·m to eliminate the decimals before solving, is option D)
D) 100
Reason:
The given expression is presented as follows;
-m + 0.02 + 2.1·m = -1.45 - 4.81·m
The number that can multiply the terms to eliminate the decimals before solving
Solution;
The number of decimal places to which the coefficient and constant values are given = 2 decimal places
Therefore, to eliminate the decimal places, the decimal point of each term has to be moved two places to the right
To move decimal points to the right x number of places is given by multiplying the number by 10ˣ
Therefore, to move the decimal point two places to the right so as to eliminate the decimal point, by multiplicative property of equality, we have;
10² × (-m + 0.02 + 2.1·m) = 10² × (-1.45 - 4.81·m)
10² = 100, therefore, we have;
100 × (-m + 0.02 + 2.1·m) = 100 × (-1.45 - 4.81·m)
-100·m + 2 + 2,100·m = -145 - 481·m
Therefore, the number the equation, -m + 0.02 + 2.1·m = -1.45 - 4.81·m, is to be multiplied by is 100

Find the number of ways 4 members from a family of 5 can line up for a photo shoot?
Final answer:
There are 120 different ways for 4 members out of a family of 5 to line up for a photo shoot. This is calculated using permutations, where the order of members matters, and is found by the formula 5! / (5-4)!.
Explanation:
To find the number of ways 4 members from a family of 5 can line up for a photo shoot, we use the concept of permutations since the order of arrangement matters.
In mathematics, the number of permutations for selecting r objects from a set of n objects is given by nPr, which is calculated as n! (n factorial) divided by (n-r)! (the factorial of the difference between n and r).
In this case, we want to arrange 4 out of 5 family members, so n = 5 and r = 4. The permutation formula gives us:
5P4 = 5! / (5-4)! = (5 × 4 × 3 × 2 × 1) / 1 = 120 ways.
Therefore, there are 120 different ways for 4 members out of a family of 5 to line up for a photo shoot.
