apply the rules for order of operstions to simplify 2 + 3 - 4 (5 × 4)
Final answer:
To simplify the expression, follow the order of operations: first perform the multiplication inside the parentheses, then multiply that result, and finally subtract it from the sum of 2 and 3. The expression simplifies to -75.
Explanation:
To simplify the mathematical expression 2 + 3 - 4 (5 × 4) we must apply the rules of order of operations, commonly remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Multiplication inside the parentheses: 5 × 4 = 20
Multiply 4 by the result of the previous step: 4 × 20 = 80
Subtract this result from the sum of 2 and 3: (2 + 3) - 80 = 5 - 80 = -75
Therefore, the expression simplifies to -75.
Remember that in subtraction, you change the sign of the number being subtracted, and then follow the rules of addition: e.g., 5 - 3 becomes 5 + (-3) = 2. Similarly, when two numbers with opposite signs multiply, the result has a negative sign: e.g., (-3) × 2 = -6.

What’s b = 3x + 9xy ? Solving the equation for x.
Answer:
x= [tex]\frac{b}{3+9y}[/tex] .
Step-by-step explanation:
Given : b = 3x + 9xy.
To find : Solving the equation for x.
Solution : We have given
b = 3x + 9xy.
Taking common 3x from right hand side
b = 3x ( 1 + 3y).
On dividing both sides by 1 + 3y .
[tex]\frac{b}{1+3y}[/tex] = 3x
On dividing both sides by 3
[tex]\frac{b}{(3+9y)}[/tex] = x .
Therefore, x =[tex]\frac{b}{(3+9y)}[/tex] .
x = b/(3 + 9y)
Further explanation[tex]\boxed{ \ b = 3x + 9xy \ }[/tex]
In the equation, there are three variables, namely b, x, and y. The coefficients of x and xy are 3 and 9, respectively.
We need solving for x from the equation.
Let us reposition it by swapping sides. The aim is to prepare x as the subject on the left-hand side.
[tex]\boxed{ \ 3x + 9xy = b \ }[/tex]
On the left-hand side, 3x is pulled out of the brackets because it is the GCF (The Greatest Common Factor) of 3x and 9xy.
[tex]\boxed{ \ 3x(1 + 3y) = b \ }[/tex]
Both sides divided by 3(1 + 3y).
[tex]\boxed{ \ x = \frac{b}{3(1 + 3y)} \ }[/tex]
Hence, the final result is
[tex]\boxed{\boxed{ \ x = \frac{b}{3 + 9y} \ }}[/tex]
That's all the steps to get x as a subject.

Write this number in standard form 12 ten thousands, 8 thousands, 14, 7 ones
The number composed of 12 ten thousands, 8 thousands, 14 tens, and 7 ones is written in standard form as 128,147.
To write the number consisting of 12 ten thousands, 8 thousands, 14, and 7 ones in standard form, each element must be placed according to its value in our base-ten number system. First, we note that 14 needs to be broken down into 'tens' and 'ones' as well.
12 ten thousands = 12 times 10,000
8 thousands = 8 times 1,000
14 tens = 14 times 10
7 ones = 7 times 1
Next, we translate these values into their numeral counterparts:
12 ten thousands = 120,000
8 thousands = 8,000
14 tens = 140
7 ones = 7
Now we simply add these numbers together:
120,000 + 8,000 + 140 + 7 = 128,147
The number 12 ten thousands, 8 thousands, 14 tens, and 7 ones written in standard form is 128,147.

What is the equation of the line perpendicular to the line y=4/9x-2 that passes through the line 4,3
Given
The line equation is
[tex]y= \frac{4}{9}x-2[/tex]
passes through the line (4,3 )
Find out the equation of the perpendicular line.
To proof
given equation is
[tex]y= \frac{4}{9}x-2[/tex]
the equation of line is in the form y = mx +c
where m = slope
c is the intercept on the y axis.
compare this equation to the above equation
we get
[tex]m =\frac{4}{9}[/tex]
In perpendicular line case
The slope of a perpendicular line is the "negative reciprocal" of the slope of the original line.
thus slope of the perpendicular line
= [tex]\frac{-9}{4}[/tex]
Than equation perpendicular line becomes
[tex]y= \frac{-9}{4}x + c[/tex]
as the line passes through the point( 4,3)
put these value in the above equation
we get
[tex]3= \frac{-9}{4}\times 4 + c[/tex]
solving the above equation
3 +9 =c
12 =c
put this value in the above equation
we get
[tex]y= \frac{-9}{4}\times x + 12[/tex]
this is equation of the perpendicular line.
Hence proved
