The equivalent expression for the indices is 17⁻⁷ × 17⁵ is 1/17²
How to create an equivalent expression for 17⁻⁷ × 17⁵?Index is the power or exponent which is raised to a number or a variable e.g in number 3⁵, 5 is the index of 3. The 3 is called the base. The plural form of index is indices.
We have different Laws of Indices, but the one applicable to this question is the product law and reciprocal law.
Product law: To multiply two variables or numbers with the same base, we need to add their powers and raise them to that base": 5² x 5³ = 5²⁺³ = 5 and P⁴ + P⁶ = P¹⁰
Reciprocal Law: If the index is a negative value, then it can be shown as the reciprocal of the positive index raised to the same variable:
8⁻² = 1/8² and b⁻⁶ = 1/b⁶
Let's use the two laws to create an equivalent expression for 17⁻⁷ × 17⁵:
17⁻⁷ × 17⁵ = 17⁻⁷ ⁺ ⁵ = 17⁻² = 1/17²
Therefore, the equivalent expression for 17⁻⁷ × 17⁵ is 1/17². The 1st option is the answer.

A pack of paper costs $1.75, including tax. Mr. Valentino wants to purchase packs of paper for his class and has a $25 budget. Write and solve an inequality to solve for the number of packs of paper Mr. Valentino can purchase, and describe the graph of the solution.
The inequality according to the the cost of pack of paper can be written as x ≤ 14.28 and Mr. Valentino can purchase a maximum of 14 packs of paper.
What is inequality?
A connection that compares two numbers or other mathematical expressions inequitably is known as an inequality in mathematics. The majority of the time, size comparisons between two numbers on the number line are made. The two most common notations for representing various forms of inequalities are as follows:
The symbol a < b indicates that a is smaller than b.
The symbol a > b indicates that a is bigger than b.
Let's assume he can buy x pack of paper.
Cost of x pack of paper will be equal to the x times cost of 1 pack of paper
i.e. Total cost = 1.75x
Now, Mr. Valentino has $25
Therefore,
1.75x ≤ 25
Inequality is ⇒ x ≤ 14.28
It tells us that Mr. Valentino can purchase only 14 packs of paper.

If h = {(1,5), (-2,6), (4, -3), (6,9)} and
m = {(3,4), (2,-2), (-2,6), (5,8)}, what is (hm) (2)? (See image below)
Answer: [tex](h\circ m)(2) = 6[/tex]
=======================================================
Explanation:
The notation [tex](h \circ m)(2)[/tex] refers to function composition
It's the same as writing [tex]h(m(2))[/tex]
According to
m = {(3,4), (2,-2), (-2,6), (5,8)}
We have m(2) = -2 since x = 2 leads to m(x) = -2
Then the output -2 is treated as the input of the outer function h(x)
Looking through
h = {(1,5), (-2,6), (4, -3), (6,9)}
shows that h(-2) = 6
Therefore, [tex]h(m(2)) = h(-2) = 6, \ \text{ and } \ (h\circ m)(2) = 6[/tex]
Optionally we can write out a table like shown below.
The row highlighted shows the input x = 2 leading to m(x) = -2, which is then plugged into h(x) to get 6 as the final output. Think of it like a chain of dominoes.

[tex]\begin{gathered} \frac{-4y}{-4}\text{ = }\frac{-2}{-4} \\ y\text{ = }\frac{1}{2}\text{ = 0.5} \\ \end{gathered}[/tex]Substitute y = 1/2 into equation (1)
x + y = 5
[tex]\begin{gathered} x\text{ + }\frac{1}{2}\text{ =5} \\ x\text{ = 5 -}\frac{1}{2} \\ x\text{ = }\frac{10-1}{2} \\ x=\frac{9}{2}\text{ = 4.5} \\ \end{gathered}[/tex]Hence, the solution to the equations is

Answer:
x = -3, 9
Explanation:
First, let us divide both sides of the equation by 10^x; this gives,
[tex]\frac{x^210^x-6x\times10^x}{10^x}=\frac{27\times10^x}{10^x}[/tex][tex]\Rightarrow x^2-6x=27[/tex]subtracting 27 from both sides gives
[tex]x^2-6x-27=0[/tex]The left-hand side can be factored as

The expression which can be rewritten using a common factor is [tex]\frac{xy}{14} (x^{2} +3y)[/tex].
According to the question,
We have the following information:
One fourteenth times x cubed times y plus three fourteenths times x times y squared.

Solve for x in the diagram below
If two angles be 10x + 5 and 15x - 30 then the value of x = 7.
How to find the value of x?Let the two angles be 10x + 5 and 15x - 30.
simplifying the above two equations, we get
10x + 5 = 15x - 30
Subtract 5 from both sides
10x + 5 - 5 = 15x - 30 - 5
Simplifying the above equations,
10x = 15x - 35
Subtract 15x from both sides of the equation
10x - 15x = 15x - 35 - 15x
Simplifying the above equation, we get
-5x = -35
Divide both sides by -5

What is the rate of change of the balance with respect to the number of deposits?
An algebraic expression known as a linear expression has terms that are either constants or variables raised to the first power. Alternatively put, none of the exponents can be greater than 1. As an illustration, while x is a variable raised to the first power, x2 is a variable raised to the second power. An illustration of a constant is 5.
Linear expression: what is it?The number of deposits will change at a 100 percent rate.
Given that, consider the image of the linear function's graph.
Currently, the graph's two points are (3, 350) and (2, 250).
Rate of change is therefore equal to (250 - 350) / (2 - 3)

Step-by-step explanation:
So you start with 200 miles to go and you are going 50 miles per hour. In the first hour, 50 miles would have been completed meaning that you subtract 50 miles from the remaining distance. Same with the other hours.
To put that in an equation, You would start with 200 and for every hour(x)you would subtract 50.
Which line on the xy-plane has a positive slope?
Line 1
Line 2
Line 3
Line 4
Please only answer with the options provided
Line 2 has a positive slope with respect to the angle made with the x-axis.
What is the slope?Slope refers to the tan of the angle with the x-axis. For example. if the line makes an angle β with the x-axis, then the slope is the tan β.
Now taking line 1,
The line is parallel to the x-axis, therefore the line makes 0 angles with the axis which gives slope 0.
Now taking line 2,
The line passes to the origin and has the equation x=y, thus the slope is 1
Now taking line 3,
The line is parallel to the y-axis, therefore the line makes 90°, thus the slope is 1/0 which gives infinity.
Now taking line 4,
The line is making an angle of 60°, therefore the line is having a slope: - [tex]\sqrt{3}[/tex]
Hence considering the above values, line 2 has a positive slope only.

Domain and Range of a Function
The domain of a function f is the set of values of the input (or independent) variable, often called x. The range is the set of values of the output (or dependent) variable, often called y, or f(x).
The function shown in the image has a shape that opens up to infinity (marked with the two arrows). This means that x can have any real value from minus infinity to plus infinity, that is, all real numbers.
Now for the range, we can see not every value of y belongs to the function. The graph decreases down to the vertex of the parabola that is located at (3,-12). This means that from y=-12 and up, the function exists, but not below this value.
Summarizing:
Domain: All real numbers
Range: y ≥ -12
