The function g(x) that results when translating the function f(x) = |x| to the left 12 units and reflecting it over the x-axis is; g(x) = -|x + 12|
What is the translation of the function?
We are given the function as; f(x) = |x|
Now, we are told that it is first translated tp the left by 12 units. Now, it is pertinent to note that when we translate a function by a units to the left it means that we add a units to the x value.
Thus, a translation of f(x) by 12 units to the left gives us;
f'(x) = |x + 12|
Now, we are told that the next transformation is reflection over the x-axis. When we reflect over the x-axis, it means a negative of the function which means we now have;
g(x) = -|x + 12|

what is the probability that Glenn will get a yellow marble
The bag has 5 marbles
3 yellow marbles
2 red marbles
"Glen chooses a marble first and then Kris chooses one" You have to determine the probability of Kris choosing a yellow marble if Glen chooses a yellow one first.
1. First you have to determine the probability that Glen choose a yellow marble first.
To do so, you have to calculate the quotient between the number of yellow marbles on the bag and the total number of marbles on the bag:
[tex]\begin{gathered} P(Y_1)=\frac{nº\text{yellow}}{\text{total}} \\ P(Y_1)=\frac{3}{5} \end{gathered}[/tex]2. and 3.
After Glen takes the first yellow marble from the bag, the total number of marbles is reduced by one and so is the number of yellow marbles on the bag, so:
New total: 4 marbles
Number of yellow marbles: 2
4.
To determine the probability of Kris choosing a yellow marble, you have to use the data on the remaining marbles on the bag. And calculate the quotient between the remaining number of yellow marbles and the remaining number of marbles:

If M is a centroid of triangle WOR and YR =16, the length of WR
side will be WR = 48.
What is the triangle's centroid?The centroid of the thing represents its center. A triangle's centroid is the point at which its three medians intersect. It can also be described as the point at which the three medians intersect.The median is a line that connects the midpoints of two sides and the opposite vertex of a triangle. A triangle is a two-dimensional shape with three sides. The three angles add up to 180 degrees.The centroid of a triangle divides the triangle's medians in a 2: 1 ratio.The ratio of the two sides will be given here as:
WY/ YR = 2/1
Determine the value of YR to determine the value of WR.
WY/16 = 2/1
WY = 32
WR will have the following value:
WR = WY+ YR
WR = 32+ 16
WR = 48
As a result, the value of the side WR is 48.

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 40 pounds each, and the small boxes weigh 25 pounds each. There are 135 boxes in all. If the truck is carrying a total of 4350 pounds in boxes, how many of each type of box is it carrying?
Number of large boxes:
Number of small boxes:
Number of large boxes will be 65.
Number of small boxes will be 70.
What is mathematical expression?
Expression in math is defined as the collection of the numbers, variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The large boxes weigh 40 pounds each, and the small boxes weigh 25 pounds each.
There are 135 boxes in all.
If the truck is carrying a total of 4350 pounds in boxes.
Let number of large boxes = x
Number of small boxes = y
Since, There are 135 boxes in all.
So, We get;
x + y = 135 ... (i)
And, The large boxes weigh 40 pounds each, and the small boxes weigh 25 pounds each and the truck is carrying a total of 4350 pounds in boxes.
So, we can formulate;
40x + 25y = 4350 ... (ii)
Solve equation (i) and (ii) as;
Multiply 40 by (i) and subtract by (ii) we get;
40x + 40y - 40x - 25y = 5,400 - 4,350
15y = 1,050
y = 70
And, x + y = 135
x + 70 = 135
x = 135 - 70
x = 65
Thus, Number of large boxes will be 65.
Number of small boxes will be 70.

If f(x) = 4x - 1 and g(x)=2x-4, what is (fog)(x)?
The value of the composite function (f o g)(x) is 8x - 17
How to evaluate the function?The definition of the functions are given as
f(x) = 4x - 1
g(x) = 2x - 4
The composite function definition is given as
(f o g)(x)
This composite function is calculated using the following composite function formula
(f o g)(x)= f(g(x))
Substitute the known values in the above equation
So, we have the following equation
(f o g)(x) = 4(g(x)) - 1
So, we have the following equation
(f o g)(x) = 4(2x - 4) - 1
Open the brackets
(f o g)(x) = 8x - 16 - 1
Evaluate
(f o g)(x) = 8x - 17

3.25 is the mean absolute deviation of 10,4,12,4,2,10,10,6
What is Mean absolute Deviation?Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set.
Given data:
10,4,12,4,2,10,10,6
Using the formula
Mean Absolute deviation = ∑(xi - x)/n
Mean = (10+ 4+ 12 +4+ 2+ 10 + 10+6)/8
= 58 / 8
= 7.25
Now,
10-7.25 = 2.75
4-7.25= -3.25
12-7.25=4.75
4-7.25=-3.25
2-7.25=-5.25
10-7.25=2.75
10-7.25=2.75
6-7.25=-1.25
mean absolute deviation=(2.75+3.25+4.75+3.25+5.25+2.75+2.75+1.25)/8
=26/8

What is arithmetic?Using the four operations, arithmetic is a branch of mathematics that deals with the characteristics of numbers.
Division, multiplication, and subtraction are the four operations. The rules for each operation are very detailed.
As an illustration of arithmetic, one of the rules of addition and subtraction is that addition increases the overall value of a number while subtraction decreases the overall value of a number.
Veronica needs to buy 13 pounds of cheese
Cheese in a container weighs = 1 pounds
Mass of cheese clerk needs to add = 13 - 1
= 12 pounds
(as 1 pound is already there)
Thus, 12 pounds of more cheese should be added to the scale to get the amount that Veronica needs which 23 pounds.
