Write each expression in simplest form. (x³/x⁻¹)⁻¹/₄
The result of simplifying the expression (x³/x⁻¹)⁻¹/₄ using the exponent rules is 1/x
To solve this exercise we have to resolve algebraic operations following the exponent rules.
(x³/x⁻¹)⁻¹/₄
Using the quotient rule that indicates that: the exponent result will be the subtraction of these exponents, we have:
(x⁽³⁻⁽⁻¹⁾)⁻¹/⁴
(x⁽³⁺¹⁾)⁻¹/⁴
(x⁴)⁻¹/⁴
Using the power of a power rule that indicates that: the exponent result will be the multiplication of these powers, we have:
x⁽⁴*⁻¹/⁴⁾
x⁽⁻⁴/⁴⁾
x⁽⁻¹⁾
As we have a negative exponent, you have to pass the exponent to the denominator:

Slope intercept form (-6,19) and (3,-2)
Answer:
[tex]y = -\dfrac{7}{3}x +5[/tex]
Step-by-step explanation:
The general equation of a line in slope-intercept form is
y = mx + b
where m = slope and b = y-intercept is rise over run
[tex]m = \dfrac {(y_{2} - y_{1})} {(x_{2} - x_{1})}[/tex]
where (x₁, y₁) and (x₂, y₂) are any two points on the line
[tex]m = \dfrac{-2 - 19}{3 - (-6)}\\\\[/tex]
[tex]\\\\m= \dfrac{-21}{9}[/tex]
[tex]m = -\dfrac{7}{3}[/tex]
So slope-intercept form is
[tex]y = -\dfrac{7}{3}x +b\\\\[/tex]
[tex]-2 = -\dfrac{7}{3}\cdot 3 +b\\\\\\\\-2 = -7 + b\\\\[/tex]
or 7 -2 = b
==> b = 5
[tex]y = -\dfrac{7}{3}x +5[/tex]
A grain of rice weighs about 0.03 g.

In the USA, about 4.3 million tonnes of rice are eaten each year.
b) 1 tonne = 1 million grams
What is the mass, in grams, of rice eaten in the USA each year?
Give your answer in standard form.
a) The mass of a grain of rice in standard form; 0.3×10⁻¹ gram.
b) The mass, in grams, of rice eaten in the USA each year: 4.6×10¹² grams.
What is described as scientific notation?Scientific notation is a handy way to shorten extremely large numbers with positive exponential values and also very small numbers with negative exponential values. To shorten long numbers in scientific notation, employ positive exponents and decimals.For the given question;
a) Weight of the rice grain is 0.03 g.
Shift the point to one decimal of the right and replace it with 10⁻¹ for this.
= 0.3×10⁻¹
Thus, the number in standard form becomes 0.3×10⁻¹ grams.
b) In USA, the rice eaten per year = 4.3 million tonnes.
1 tonne = 1 million grams
And, we know, one million can be written as.
1 million = 10⁶
4.3 million tonnes = 4.6×10⁶ tonnes.
Now, if 1 tonne = 1 million grams.
Then, multiply both side by 4.6×10⁶.
4.6×10⁶ × 1 tonne = 4.6×10⁶×1 million grams.
4.6×10⁶ tonnes = 4.6×10⁶ million grams.
Again convert million as 10⁶.
= 4.6×10⁶×10⁶
= 4.6×10⁶⁺⁶
= 4.6×10¹²
Thus, in USA 4.6×10¹² grams of rice is eaten each year.

The coordinates of the resulting point C' are (-5, 4).
What are coordinates?A coordinate system in geometry is a system that uses one or more numbers, or coordinates, to determine the position of points or other geometric elements on a manifold, such as Euclidean space. The order of the coordinates matters, and they are sometimes identified by their position in an ordered tuple and other times by a letter, as in "the x-coordinate."Since we know that rotating a point 270° counterclockwise about the origin causes the point (x,y) to become (-y, x), we can swap the positions of the x and y coordinates and make y negative.
We have, using the above transformation:
(x, y) ⇒ (-y, x)(4, 5) ⇒ (-5, 4)Therefore, the coordinates of the resulting point C' are (-5, 4).

D. 1/12 (3+ 4+ 9) = 1/12(16) = 16/12 = 1 1/3
Answer:
B is the correct use of the commutative property.
Step-by-step explanation:
Let's use the process of elimination.
We can see that A is not using the commutative property because the sum of the numbers in the parentheses are just being combined.
C doesn't work because they just added 1/3 and 3/4, which doesn't work.
And finally D doesn't work because they used the distributive property instead.
B works because they combined 1/4 and 3/4 to equal 1, an easy number to calculate, and added 1/3 to get a final answer is 1 1/3.
