Step-by-step explanation:
Solution :
To solve the above equation we will follow the BODMAS rule.
[tex]\small\pink\bull[/tex] BODMAS is an order of mathematic operations.[tex]\small\pink\bull[/tex] BODMAS rule is to be followed while solving expressions in mathematics.It stands for :
[tex]\begin{gathered}\quad\begin{gathered} \small \begin{array}{l} \star \: \rm B= bracket \\\star \: \rm O= order \: of \: power \: \\\star \: \rm D= division \\\star \: \rm M= multiplication \\ \star \: \rm A= addition \\ \star \: \rm S=subtraction \end{array}\end{gathered}\end{gathered}[/tex]
Solving the question by bodmas rule :
[tex]\implies\tt{\dfrac{15 - 7 + 3(6 + 2)}{{2}^{3}}}[/tex]
[tex]\implies\tt{\dfrac{15 - 7 + 3(8)}{2 \times 2 \times 2}}[/tex]
[tex]\implies\tt{\dfrac{15 - 7 + 3 \times 8}{4\times 2}}[/tex]
[tex]\implies\tt{\dfrac{15 - 7 + 24}{8}}[/tex]
[tex]\implies\tt{\dfrac{39- 7}{8}}[/tex]
[tex]\implies\tt{\dfrac{32}{8}}[/tex]
[tex]\implies\tt{\cancel{\dfrac{32}{8}}}[/tex]
[tex]\implies\tt{\underline{\underline{\red{4}}}}[/tex]
Hence, the answer is 4.

Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (negative 4, 1), (negative 4, 4), (2, 1). What are the coordinates of point S'? (2, 1) (1, –2) (–1, –2) (2, –1)
Answer:
(-2,-1)
Step-by-step explanation:
Given
[tex]Q =(-4,1)[/tex]
[tex]R = (-4,4)[/tex]
[tex]S = (2,1)[/tex]
180 degrees rotation
Required
Determine the coordinate point S'
For a 180-degree rotation, the transformation rule is: (x, y) to (-x, -y)
So:
[tex]S = (2,1)[/tex] ==> [tex]S' = (-2,-1)[/tex]
Hence, the coordinate point of S' is (-2,-1)

Mr. Rector and Ms. Mitchell are grading papers. Mr. Rector can grade 24 papers in 10 minutes. Ms. Mitchell can grade 30 papers in 8 minutes. How many more papers per minute can Ms. Mitchell grade?
Answer: 1.35
Step-by-step explanation:
Answer:
1.35
Step-by-step explanation:
We need to identify our independent variables and dependent variables.
The number of papers graded depend on the amount of time.
The amount of time is the independent variable
The papers graded depends us the dependent variable
Divide the independent variable by the dependent variable to find papers per minute
For Ms.Mitchell the papers per minute is
For Mr.Rector, the papers per minute is
Subtract 2.4 from 3.75.
The answer is 1.35

Which statement describes the end behavior of the function f(x) = 8|x − 1| + 13?
A.
As x approaches negative infinity, f(x) approaches negative infinity.
B.
As x approaches negative infinity, f(x) approaches positive infinity.
C.
As x approaches positive infinity, f(x) approaches negative infinity.
D.
As x approaches positive infinity, f(x) is no longer continuous.
The statement that describes the end behavior of the function f(x) = 8|x − 1| + 13 is:
As x approaches positive infinity, f(x) approaches negative infinity.C.
Let's analyze the function.
The function f(x) = 8|x − 1| + 13 involves the absolute value of x − 1, which means that the expression inside the absolute value will always be non-negative.
x approaches positive infinity, the value of x − 1 also approaches positive infinity.
Since the absolute value of a positive number is equal to the number itself, we can simplify the expression to f(x) = 8(x − 1) + 13.
As x approaches positive infinity, the term 8(x − 1) becomes larger and larger, making f(x) approach negative infinity.
The constant term 13 does not have a significant impact on the end behavior as x becomes increasingly large.

Can A Expert Help Me Find The Value Of X Please (Geometry)
Answer:
x=75
Step-by-step explanation:
Okay so the sum of the angles inside this figure is
(6-2)*180=4*180=720
now, we can find 4 of the interior angles becuase they are supplementry.
180-54=126
180-51=129
There are two of each so we can just do 2(126)+2(129)=252+258=510
That means the two remaining angles that are supplementary to x equal to 510. they are equal, so we know the interior angles equal 720-510=210/2=105
Since the angles are supplementary, x=180-105=75
BTW: Supplementary angles are angles that equal to 180 degrees.
f(x) = –x^2 – 4x
Find f(-1)
Answer:
3
Step-by-step explanation:
Evaluate F(x) = –x^2 – 4x by substituting -1 for x:
F(-1) = –(-1)^2 – 4(-1)
This becomes:
F(x) = –1 + 4 = 3

what is the slope of y=-4x-8
Answer:
-4
Step-by-step explanation:
y = mx + b
Answer:
-4
Step-by-step explanation:
y=mx+b
m is slope
b is y-intercept
So you line y=mx+b and y=-4x-8
-4 is replacing m so -4 is the slope

A pack of 5 of board games costs $75.
If there is a direct proportion between the price (y) and number of board games (2), which equation represents the
situation?
A
y = 2
y = 15.2
y = 52
y = 75.00
Answer:
C. y=5x
Step-by-step explanation:
I'm pretty sure that it's y=5x, because it says that y represents the price, and that 2 represents that amount of board games. The price is $75, and the number of board games is 5. So the answer should be y=5x.

Is b = 5 a solution to the inequality below?
b<1
yes
no
Answer:
No
Step-by-step explanation:
The given inequality is b < 1. We determine whether or not b = 5 is a solution by substituting 5 for b and asking ourselves whether the resultant inequality is true or not:
5 < 1 is FALSE and so b = 5 is NOT a solution of the given inequality.
