The expression can be simplified through division of the exponential (power).

In the given expression, if the powers have the same base, we can actually divide the power.  In order to carry out the division of the exponential (power), we can subtract their exponential.

In the general form, a-m=1/am

As there are two different base terms x and y in the numerator and denominator, we will subtract the powers of x terms and powers of y terms.

Let us simplify the x terms,

x¹/₂÷x³/₄=x(1/2)-(3/4)  

Solving the powers,(½)–(¾)=(2/4)–(¾)=(2-3)/4=-1/4

x¹/₂÷ x³/₄=x(1/2)-(3/4)= x-1/4  

Let us simplify the y terms,

y⁻¹/₃÷y¹/₂= y(⁻¹/₃)-(¹/₂)

Solving the powers, (-1/3)-(1/2)=(-2/6)-(3/6)=-5/6

y⁻¹/₃÷y¹/₂= y(⁻¹/₃)-(¹/₂)=y-5/6

Putting the terms together gives us,

x-1/4 *y-5/6

It can be expressed as a fraction as a-m=1/am

x-1/4 *y-5/6=1/x1/4y5/6

Hence, x¹/₂ y⁻¹/₃ / x³/₄ y¹/₂= x-1/4 *y-5/6=1/x1/4y5/6

Angles <6 and <12 are  alternate interior angle.

An interior angle is an angle that is inside a shape. It can also be described as an angle that lie in the area bounded between two parallel lines that are intersected by a transversal. In the given image, angles 6 and 11 are interior angles. The sum of interior angles is 180 degrees.

An alternate interior angle is an angle that is formed when two parallel lines are crossed by a transversal. The angle formed on the inner side of the parallel lines, and on the opposite sides of the transversal are called alternate interior angles. The alternate interior angles are angles 6 and 12.

A corresponding angle is an angle that is on  the same side of one of two lines cut by a transversal and on the same side of the transversal. Angle 4 and 12 are  corresponding angles.

The function y = 100 ( 0.25 ) ˣ is an exponential decay function.

An exponential function is defined as y = a ˣ where x is a variable, and a is a constant called the base of the function.

We are given a function:

y = 100 ( 0.25 ) ˣ

We need to tell whether is is a exponential growth or decay function.

We can see that the value of a ˣ = (0.25) ˣ

So, the value of a = 0.25.

Since, it is a decimal and not an integer, its value will decrease with the increase in exponent x.

So, it will be a exponential decay function.

Therefore, we get that, the function y = 100 ( 0.25 ) ˣ is an exponential decay function.

The equation 3x - 1 = 1 - 3x has a solution x = 1/3

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

The expression is given as;

3x - 1 = 1 - 3x

Now, To check the solution is exist or not we can solve the equation as;

3x - 1 = 1 - 3x

Add '3x' both side,

3x - 1 + 3x = 1 - 3x + 3x

6x - 1 = 1

Add '1' both side,

6x - 1 + 1 = 1 + 1

6x = 2

Divide '6' both side,

x = 1/3

Hence, The equation 3x - 1 = 1 - 3x has a solution x = 1/3.

Given the expression is (10x)⁺¹.

Firstly, we will simplify the given expression (10x)⁺¹ for x=0.

Substitute the value x=0 in given expression, we get

(10x)⁺¹=(10×0)⁺¹

As we know that something multiply to zero is 0.

So, we get

(10x)⁺¹=0

Now, we will simplify the given expression (10x)⁺¹ for x=-2.

Substitute the value x=2 in given expression, we get

(10x)⁺¹=(10×2)⁺¹

Now, we will know that if we multiply any number with 2 we get twice of it, we get

(10x)⁺¹=(20)⁺¹

(10x)⁺¹=20

Furthermore, we will simplify the given expression for x=-2.

Substitute the value x=-2 in given expression, we get

(10x)⁺¹=(10×(-2))⁺¹

Now, we will know that if we multiply any number with 2 we get twice of it, we get

(10x)⁺¹=(-20)⁺¹

and the long hand (minute had) is at 45 minutes

Step-by-step explanation:

Step-by-step explanation:

per the laws of intersecting lines the angles on one side of any of the lines must be the same as the angles on the other side of that line - just left-right mirrored.

for that reason, CGE = DGF.

also to remember : the sum of all angles around a point on one side of a line is always 180° (because they represent a half-circle with that point being the center). in other words, these angles are supplementary (together 180°).

therefore,

180 = 62 + 32 + DGF

DGF = CGE = 180 - 62 - 32 = 86°

Answer:

The resultant expression is 48 + 30 = 6 (8 + 5) = 6 (13) = 78.

Step-by-step explanation:

It is given that the GCF of 48 and 30 to write the sum of the two numbers as the product of their GCF and another sum.

Now,

The largest number that can divide two numbers is known as the GCF. The formula for 48 plus 30 is as follows;

=> 48 + 30

=> 6 (8 + 5)

=> 6 (13)

=> 78

Here, the numbers are given as 48 and 30 so, the expression is;

=> 48 + 30

And their GCF is 6 so, we get;

=> 48 + 30 = 6 × 8 + 6 × 5

=> 48 + 30 = 6 (8 + 5)

=> 48 + 30 = 6 (13)

=> 48 + 30 = 78

The expression as a single logarithm is log (2/3).

In mathematics, the inverse function of an exponent is a logarithm. This means that the logarithm of a fixed number, such as a, at base b, is used to represent the exponent to which the fixed number must be raised in order to create the number x.

The general properties of logarithm for a fixed base are:

Now from the above properties of logarithms we can calculate:

log 8-2 log 6+log 3

=log 8 + log 3 - 2log6

We know that logₐx+logₐy=logₐxy and logₐxⁿ=n logₐx

∴log(8×3) -log(6²)

=log 24 - log 36

Again we know that logₐx-logₐy=logₐ(x/y)

=log(24/36)

=log(2/3)

Line a and b are parallel lines.

These parallel lines are cut by a transversal.

The traversal forms angle relationship as follows:

5x - 7 = 3x + 17 (alternate angles)

The variable x and y can be found as follows

5x - 7 = 3x + 17

5x - 3x = 17 + 7

2x = 24

x = 24 / 2

x = 12

Therefore,

4y + 3 + 3x + 17 = 180

4y + 3 + 3(12) + 17 = 180

4y + 3 + 36 + 17 = 180

We have to find the x corresponding to f(x) = 24

For our convenience, let f(x) = y

This equation implies y in terms of x.

Isolating x to one side of the equation, we get,

x = (y - 8)/-4 = (8-y)/4

This equation gives x in terms of y.

So when f(x) = y = 24,

x = (8-24)/4

The point-slope equation of something like the line, with slope equal to 5/6 but instead passing through the point at(22 , 12), is:

A line's equation can be stated in three different ways:

The typical form of a line equation is ax + by = c, where a but rather b are the coefficients of variables x and y, respectively, as well as c is a constant if all possible values must be integers. In the meantime, the slope-intercept form is given by the formula y = mx + b, where m is the line's slope as well as b is the y-intercept. Given the slope m and a point on the line (x, y), we can formulate the equation using point-slope form, (y - y1) = m. (x - x1).

To build up the equation, use the point slope form and enter in the values.

(y - y1) = m(x - x1)

where;

m = 5/6

(x1 , y1) = (22 , 12)

(y - 12) = 5/6(x - 22)

In slope-intercept form, the equation of the line is:

(y - 12) = 5/6(x - 22)

y - 12 = 5/6 x - 110/6

y = 5/6 x - 19/3

In standard form, the equation of the line is:

y = 5/6 x - 19/3

5/6 x - y = 19/3

Multiplying both sides by 6,

5x - 6y = 38.

The point-slope equation of something like the line, with slope equal to 5/6 but instead passing through the point at(22 , 12), is:
