Rewrite in simplest radical form
1
x
−3
6
Answer:
To simplify the given radical form, we must recall some properties of exponents as shown below. 1. 1/x⁻ⁿ = xⁿ 2. x¹/² = √x Now, going back to 1/x⁻³/⁶, we have 1/x⁻³/⁶ = x³/⁶ x³/⁶ = x¹/² x¹/² = √x Using the properties provided, we have a simplified form of √x. Answer: √x

What is the inverse relation of the function whose equation
is y = 3x – 2?
oy = x
o y = 3x + 2
o y = 2x - 3
x + 2
y =
3
Answer:
The inverse of the function is;
x = (y + 2)/3
Step-by-step explanation:
Here in this question, we shall be calculating the inverse of a function.
The function is;
y = 3x - 2
Firstly, let w = x;
y = 3w -2
y + 2 = 3w
w = (y + 2)/3
Now replace w by x
x = (y + 2)/3
This is the inverse of the function

Answer:
g(f(x)) = 36[tex]x^{4}[/tex] - 54x² + 12
Step-by-step explanation:
Substitute x = f(x) into g(x) , that is
g(6x²)
= (6x²)² - 9(6x²) + 12
= 36[tex]x^{4}[/tex] - 54x² + 12
Simplify each using the distributive property and/or combining like terms:
1.) 4x - 91X + 8)
2.) 6x-4 +2x +9
3.) 8x + 3+ 7xy-2 + x-5xy
Solve for x.

O x = 8
O x = 4
O r=-4
O = -8
Solve for the variable. Show all work. |6x| - 8 = -8
Answer:
x = 0
Step-by-step explanation:
|6x| - 8 = -8
Add 8 to each side
|6x| - 8+8 = -8+8
|6x| = 0
Removing the absolute value
6x = 0
Divide by 6
6x/6 = 0/6
x = 0

Solve the following equation for x? -5(1-5x)+5(-8x-2=-4X-8x
Answer:
-5
Step-by-step explanation:
-5(1-5x)+5(-8x-2) = -4x-8x
-5+25x-40x-10 = -12x
-15-15x = -12x
-15 = -12x + 15x
-15 = 3x
x = -15 ÷ 3
∴x = -5
The formula a = m − n represents the actual cost, a, of an item with original price m after a coupon for n dollars off is applied. Solve the formula for the amount of the coupon. Group of answer choices n=a+m n=m−a n = a − m n = −m − a
Answer: Option B.
Step-by-step explanation:
The given formula is
[tex]a=m-n[/tex]
where,
a = actual cost of an item.
m = Original price
n = Amount of coupon
We need to solve the formula for the amount of the coupon (n).
In means, we need to isolate n in the given formula.
We have,
[tex]a=m-n[/tex]
Subtract m form both sides.
[tex]a-m=m-n-m[/tex]
[tex]a-m=-n[/tex]
Multiply both sides by -1.
[tex]-(a-m)=n[/tex]
[tex]-(a)-(-m)=n[/tex]
[tex]-a+m=n[/tex]
So, [tex]n=m-a[/tex].
Therefore, the correct option is B.

Identify square root of 3 as either rational or irrational, and approximate to the tenths place.
Answer:
Irrational
[tex]\sqrt{3}[/tex] = approx. 1.7
Step-by-step explanation:
The square root of 3 is irrational, because 3 is not a perfect square.
For example, 4 is a perfect square, so the square root (2) will be rational.
The square root of 3 is 1.73205080757,
and we can round this to 1.7 for the tenths place

Answer:
Step-by-step explanation:
14X - 2

96
The value of the expression at x = 7 will be 96.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression is 14x - 2. The value of x is 7. The value of the expression at x =7 will be calculated as:-
E = 14x - 2
E = 14 x 7 - 2
E = 96
Therefore, the value of the expression at x = 7 will be 96.
