The simplified expression of 3 (-5 + 2x) is -15 + 4x.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

3 (-5 + 2x)

The distributive property of multiplication over addition states that,

a x (b + c) = a x b + a x c

Now,

3 x (-5 + 2x)

3 x (-5) + 2 x (2x)

-15 + 4x

Thus,

The simplified expression is -15 + 4x.

The average rate of change for the interval from x = 5 to x = 6 can be calculated by taking the derivative of the quadratic function and evaluating it at the midpoint of the interval (x = 5.5).

Given that the vertex of the function is at (1, 0), the equation of the quadratic function is in the form of:

f(x) = a(x-1)^2 +0

The derivative of the function is:

f'(x) = 2ax - 2a

We know that the vertex of the function is at (1,0), which means that the value of a is 0.

So the derivative of the function is 0.

Therefore the average rate of change for the interval from x = 5 to x = 6 is 0.

As per the unitary method, the cost of 8 pear is at the rate of $12.

The term unitary method is defined as a process of finding the value of a single unit, and based on this value and then we can find the value of the required number of units.

Here we have given that the grocery store the cost of 6 pear is $9.

Let us consider that x be the cost of one pear.

Here we know that the the cost of 6 pear is $9.

Then the cost of one pear is calculated as,

=> x = 9/6

When we simplify this one then we get, the cost of one pear as,

Simply put, interest is the cost of borrowing money, whether it be through a student loan, a mortgage, or a credit card. When you borrow money, you typically have to pay it back along with interest that is calculated as a percentage of the loan amount. There are a few exceptions, such as when you pay off your credit card balance in full each month or when you have a promotional 0% interest rate.

In linear equation, The number of pounds of apples is 12 and the number of pounds of raspberries is 20.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                    Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Given that, the cost of a pound of apples = $2.25 and the cost of a pound of raspberries = $1.50.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of pounds of apples be x, then the number of pounds of raspberries(y) be y=x+ 12

Now, the total cost of apples = The number of pounds of apples × The cost of a pound of apples

=x × 1.50

= 1.50x

The total cost of raspberries = The number of pounds of raspberries × The cost of a pound of raspberries

=(x+12) × 3

=3x+ 36

So, the total cost = The total cost of apples + The total cost of raspberries

⇒ 72 = 1.50x+ 3x+ 36

⇒  72 = 4.5x + 36

        4.5x = 72-36

            x =  8

So, y= x+ 12 = 20

Therefore, the number of pounds of apples is 12 and the number of pounds of raspberries is 20.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. An expression, rule, or law in mathematics that establishes the relationship between an independent variable and a dependent variable (the dependent variable).

Here The graphs of g may be obtained from the graph of f by shifting up c units. The graph moves downward if we take c out of f(x). Let h(x) = f(x)-c shifting downward c units yields this graph of h from the graph of f.

Now given function f(x)= 4IxI.

It is stated that its graph of  is obtained by reflecting a graph of f(x)= 4IxI over the x-axis.

When a figure is reflected across the x-axis, the rule for reflection is

Step-by-step explanation:

Answer:

(1,4)

Step-by-step explanation:

The average rate of change of h(x) on the interval [-1, 8] is r = -3.6

For any function, the average rate of change on an interval [a, b] is given by:

r = ( f(b) - f(a))/(b - a)

In this case, the function is:

h(x) = -x^2 + 4x + 12

And we want to find the average rate of change on the interval [-1, 8]

Evaluating the function in these values we will get:

h(-1) = -(-1)^2 + 4*(-1) + 12

h(-1) = -1 - 4 + 12 = 7

h(8) = -(8)^2 + 4*8 + 12 = -20

Then the average rate of change is:

r = ( h(8) - h(-1) )/(8 + 1)

r = (-20 - 12)/9

r = (-32/9) = -3.6

Answer: v would be root2 and u would be 2

Step-by-step explanation:

The midpoint formula is used to calculate elasticity because it overcomes the limitations of the traditional method.

The old point-slope method has significant drawbacks that are overcome by the midpoint formula, which determines the elasticity of demand. The elasticity of demand refers to how sensitively a good's quantity desired is to a price shift. Inelastic goods are those in which a little price shift causes a large change in quantity demanded, while elastic goods are those in which a small drop causes a small change in quantity demanded.

The conventional point-slope formula for elasticity employs the change in quantity and price at a particular point, which might be deceptive in some circumstances. Contrarily, the midpoint formula determines the elasticity of demand by averaging the quantity and price at the beginning and end and utilising the percentage change in both.
