Tickets for an Amtrak train cost $17 for children and $36 for adults. Josie paid $2,297 for a total of 77 tickets. How many children tickets and how many adult tickets did Josie buy?

The given expression can be simplified by using rules of exponents.

There will be two rules applied, one for negative exponent and other for multiplication of exponents.

The expression can be solved by using either of the rules first. In this case, we will solve for the negative exponent first.

The base term x has a negative exponent of -4/7.  The negative exponent rules states that the term with the negative exponent can be expressed in a reciprocal or reverse form without the negative sign.

In the general form, x^-a=1/x^a.

Applying the rule here,

(x^⁻⁴/₇)^7=(1/x^4/7)^7

Now multiplying the powers and simplifying,

(1/x^4/7)^7=1^7/x^(4/7)*7=1/x^4

The simplest form of the expression (x^⁻⁴/₇)^7 is 1/x^4

Answer:

y = 2

Step-by-step explanation:

- 3x + 9y = 57 ← substitute x = - 13 into the equation

- 3(- 13) + 9y = 57

39 + 9y = 57 ( subtract 39 from both sides )

9y = 18 ( divide both sides by 9 )

y = 2

Answer: y is 2

solved it with a calculator.

The step 2 is incorrect angle o and angle p form supplementary angles not alternate interior angle that is :

∠o +  ∠p = 180°

What are alternate interior angle ?

An alternate interior angle is one formed on the inside side of two parallel lines and opposite on the outer side of the transversal when those two parallel lines are intersected by a transversal and they are equal.

Alternate angles between a transverse and parallel lines are equal .

Here, the step 1 is correct :

as the sum of angles of a triangle is 180 degree therefore,

∠m +∠n + ∠o = 180°.............(1)

the step 2 is incorrect :

as angle o and angle p form supplementary angles not alternate interior angle therefore it will be :

∠o +  ∠p = 180°........(2)

after that step 3 and 4 is correct to get the final result as :

step 3 : ∠m +∠n + ∠o = ∠o +  ∠p

step 4 : ∠m +∠n = ∠p

Therefore, the step 2 is incorrect angle o and angle p form supplementary angles not alternate interior angle.

y = 3x -5 is the equation of the line parallel to the line and going through the point (4,7). The format is slope intercept.

A method of formulating a line's equation that makes it simple to identify the slope and y-intercept is known as the slope-intercept form. The point where the line crosses the y-axis is known as the y-intercept, and the slope refers to how steep the line is.

Using the information provided,

y= 3x – 5

First, we must keep in mind that parallel lines have an equal slope.

In essence,

m1 = m2 if line 1 and 2 are parallel.

Y = mx + c is the slope-intercept form of the equation; y = 3x + 6, which already has this form.

incline of the m1 = 3.

Consequently, m1 = 3 = m2.

The slope of the parallel line, m2 = 3 and the line passes through the point (4,7).

Therefore;

3 = (y - 7)/(x-4)

By cross product;

3x - 12 = y - 7

y = 3x - 5

After solving the equation In (2m + 3) = 8, the value of m is equal to 5/2.

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

We have been asked to find m in (2 m+3) = 8

⇒ (2 m+3) = 8

Five more than means add 5+5 three times the smaller number:

 3x equals the larger number:  = y 3x + 5 = y    equation 2

 From equation 1x + y = 29subtract x from both sidesy = 29 - x 

We now have two things that are both equal tothe larger number y.

  They must be equal to each other. 
3x + 5 = 29 - x

 Add x to both sides 3x + x + 5 = 29 - x + x4x + 5 = 29

subtract 5 from both sides 4x + 5 - 5 = 29 - 54x = 24

The solution of the radical equation of x is 1.

A linear equation in one variable is an equation which can be represented in the form of ax+b where x is the variable and 'a' is the coefficient and 'b' is  the two constants.

A radical equation is defined as an equation where the variable is under a radical or root.

We know that n-th root of a variable x can be written as x to the power of (1/n). Mathematically : [tex]\sqrt[n]{x} =x^{\frac{1}{n} }[/tex]

In the given equation:

∛x-1=√x-1

adding 1 to both sides we get:

or, ∛x=√x

Cross multiplying we get:

or, ∛x/√x =1

We know that (aˣ/aⁿ)=a⁽ˣ⁻ⁿ⁾

therefore :

or, [tex]x^{\frac{1}{3}-\frac{1}{2} }=1[/tex]

or, [tex]x^{-\frac{1}{6} }=1[/tex]

The coordinates of the midpoint M are (-1/2, 1), and the length of YZ is approximately 14.32 units.

We have,

To find the coordinates of the midpoint M of the line segment YZ, we can use the midpoint formula:

Midpoint M = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)

Where (x₁, y₁) and (x₂, y₂) are the coordinates of the endpoints Y and Z, respectively.

Given:

Y(1, -6) and Z(-2, 8)

Now, apply the midpoint formula:

Midpoint M = ((1 + (-2)) / 2, (-6 + 8) / 2)

Midpoint M = (-1 / 2, 2 / 2)

Simplify:

Midpoint M = (-1/2, 1)

To find the length of YZ, we can use the distance formula:

Length of YZ = √[(x₂ - x₁)² + (y₂ - y₁)²]

Given:

Y(1, -6) and Z(-2, 8)

Now, apply the distance formula:

Length of YZ = √[(-2 - 1)² + (8 - (-6))²]

Length of YZ = √[(-3)² + (8 + 6)²]

Length of YZ = √[9 + 196]

Length of YZ = √205

Length of YZ ≈ 14.32 (rounded to the nearest tenth)

Thus,

The coordinates of the midpoint M are (-1/2, 1), and the length of YZ is approximately 14.32 units.
