What is the expanded form for 45 squared?

Answer:

a. Write an inequality that demonstrates this situation

Let x be the number of $5 t-shirts Tyrone can buy

The inequality that demonstrates this situation is:

x*5 + 22 <= 95 - 15

b. solve your inequality

x5 + 22 <= 80

x5 <= 58

x <= 11.6

x <= 11

c. Explain what your answer means to Tyrone

Tyrone has $95 to spend, he already bought pants for $22, so he has $95-22 = $73 left to spend. He wants to have at least $15 left over after buying t-shirts, so he can buy up to $73-15 = $58 worth of t-shirts. Each t-shirt costs $5, so he can buy a maximum of 11 t-shirts (58/5=11.6) with no remainder. So Tyrone can buy 11 t-shirts and he will have $73-11*5 = $18 left. This means that Tyrone can buy 11 t-shirts and still have $18 left over.

A two-dimensional (2D) coordinate system is a system used to define the position of points in a two-dimensional plane.

A 2D coordinate system can also be used to represent other kinds of data, such as temperature, elevation, or pressure. In this case, the two coordinates are usually called the x-axis and y-axis, and they are both used to measure the same physical quantity.

It is most commonly used in mathematics and engineering to plot graphical data such as graphs, charts, and diagrams. In a 2D coordinate system, each point is represented by two numbers, called coordinates, which indicate the position of the point in relation to a fixed reference point, called the origin. These coordinates usually describe the horizontal (x) and vertical (y) distances between the point and the origin. The set of all points in the 2D coordinate system is called the coordinate plane.

Answer: the total spent on the meal is $88.25875.

Step-by-step explanation:

The total spent on the meal can be calculated by adding the cost of the meal, the tax, and the tip.

First, we need to calculate the cost of the tax: 72.5 x 0.0675 = 4.88375

Then we need to calculate the cost of the tip: 72.5 x 0.15 = 10.875

Finally, we add the cost of the meal (72.5), the tax (4.88375) and the tip (10.875) to find the total cost of the meal: 72.5 + 4.88375 + 10.875 = 88.25875

Therefore, the total spent on the meal is $88.25875.

Answer:

10 and 16

Step-by-step explanation:

let on number be x then the other number is x + 6

sum the 2 numbers and equate to 26

x + x + 6 = 26

2x + 6 = 26 ( subtract 6 from both sides )

2x = 20 ( divide both sides by 2 )

x = 10

x + 6 = 10 + 6 = 16

the 2 numbers are 10 and 16

By solving the given inequality in question, i.e -8+2x>4 , the solution obtained is x>6, which means the inequality satisfies for all the values of x that are greater than 6.

An inequality is a statement that compares two values and asserts that one value is greater than, less than, or not equal to the other value. Inequalities are used to describe a range of values that a variable can take on. The most common symbols used to express inequalities are ">", "<", "≥" and "≤", which represent "greater than", "less than", "greater than or equal to" and "less than or equal to" respectively.

An example for inequality can be , the inequality x > 2 , which states that x is greater than 2, which means that any value of x that is greater than 2 satisfies the inequality.

Inequality can be solved either graphically or algebraically. The solution of an inequality is the set of all values that make the inequality true.

To solve the inequality -8 + 2x > 4, you can follow these steps:

So the solution of the inequality is x > 6.

This means that x is greater than 6. So any value of x that is greater than 6 satisfies the inequality.

Writing y = log2 x or f(x) = log2 x represents the logarithmic function for the equation x = 2y. Even today, the base is still 2. Y equals log base b of x, or more simply, "y equals log to the base b of x," is how y = logb x is typically read. Similarly to exponential functions, b > 0 and b 1.

In mathematics, a differential equation is an equation involving one or more functions and their derivatives. The derivative of a function defines the rate of change of the function at some point.

According to the given Question:

Differential equation:

In mathematics, a differential equation is an equation that relates one or more unknown functions and their derivatives.  In applications, a function generally represents a physical quantity, a derivative its rate of change, and a differential equation defines the relationship between the two. Such relationships are common. Therefore, differential equations play an important role in many fields such as engineering, physics, economics and biology.

The study of differential equations consists primarily of studying their solutions (the set of functions that satisfy each equation) and the properties of those solutions. Only the simplest differential equations can be solved with explicit formulas. However, many properties of solutions to particular differential equations can be determined without exact computation. In many cases, when a closed formula for the solution is not available, the solution can be approximated numerically using a computer. Although the theory of dynamical systems focuses on qualitative analysis of systems described by differential equations, many numerical methods have been developed to determine solutions with some degree of accuracy.

A first-order linear differential equation is an equation that can be written in the form y0 + p(x)y = q(x). where p and q are continuous functions on the interval I. The second-order linear differential equation has a similar form.

Given:

An 'Or' inequality is also referred to as a disjunction.

In other words, there is no connection on the number line between the range of values that meet either component of the inequality. Finding a truthful statement that satisfies either one of the inequality conditions or both inequality conditions is the aim whenever 'Or' compound inequalities are solved.
