Answer:

(1) y = 8.45x

(2) Total cost: $42.25

Step-by-step explanation:

Let's see by constructing a first-hand example of the information we have.

$101.40 = 12x

Divide 12 on both sides.

When we divide 12 from both sides, we get the simplified answer of:

x = 8.45

This means that each pizza will be $8.45 each, therefore this will be out=r equation

y = 8.45x

(where x is the number of pizzas and y is the total amount cost.

To find the cost of 5large pepperoni pizzas, we use our equation above (y = 8.45x) and input a 5 in x;

y = 8.45(5)

y = 42.25

The total cost for the 5 pizzas will be $42.25.

The function for profit given the conditions for  revenue and expense is P = $20a - $1,600.

The first claim is incorrect because profit is $400

The first claim is incorrect because profit is $4,400.

Profit is revenue less total cost. Total cost consists of fixed cost and variable cost. Fixed cost is the cost that does not change with the level of output. Variable cost is the cost that changes with output. It increases as the level of output increases. Revenue is output multiplied by price per unit.

Profit = revenue - total cost cost

Profit = (price x output) - fixed cost - variable cost

P = ($45 x a)  - $1,600 - ($25 x a)

P = $45a - $1,600 - $25a

P = $20a - $1,600

Where:

P = profit

a = output

Profit when 100 units is sold:

P = (20 x 100) - $1,600

$2,000 - $1,600 = $400

Profit when 300 units are sold

P = (300 x 20) - $1600

$6,000 - $1,600 = $4,400

Answer:

Hhhhhhhhhhhhhhhhhh : x=-2

Answer:

f(-2) = 18

Step-by-step explanation:

In order to calculate a function of x, we replace x
For example
f(x) = x
f(-2) = -2

In this specific scenario

f(x) = 3 * (4 - x)
f(-2) = 3 * (4 - -2)

- -2 turns positive
f(-2) = 3 * (4 + 2)

Now we use PAMDAS (parentheses, exponents, multiplication, division, addition) as an operation order, so we first solve the parantheses
f(-2) = 3 * 6

f(-2) = 18

Betty spent $90 and Nan spent $ 30

Mathematical expressions can be used to depict situations or issues, and algebra is the field of mathematics that does this. For a mathematical expression to have meaning, it needs to include variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division. Algebra is used in every area of mathematics, including coordinate geometry, calculus, and trigonometry. A straightforward algebraic expression is 2x + 4 = 8.

Given that :While shopping, Betty spent three times as much as Nan. And they spent a total of $120,

Let the Betty spent total $x and Nan spent total $Y

then,

x = 3y ....(i)

x +y =120 .....(ii)

put value of c from i equation to equation ii

4y = 120

y = 30

x = 90

Hence Betty spent $90 and Nan spent $ 30

A point that lies in the middle of a line and is equally spaced from its ends is the line's midway. The formula for the line's midpoint is [(x)1 + (x)2]/2, [(y)1 + (y)2]/2 if the line's endpoints are (x)1, (y)1, and (x), (y), respectively.

Using the equations [(x)1 + (x)2]/2, [(y)1 + (y)2]/2, one may get the midway. Here, the coordinates of two points are (x), (y), (x)2, (y)2, and the midway is a location that is equally spaced from both of these positions.

The exact middle number between two numbers is referred to as the midway. The midpoint calculation is the same as the two-number average calculation. Therefore, by adding any two numbers together and dividing by two, you may find the halfway between any two integers.

The distance formula, which is derived from the Pythagorean Theorem, is employed to determine the separation between two points in the plane. The Pythagorean Theorem is based on a right triangle where the angles are a and b.

For the given functions, we have that:

a) The numeric value of the division function at x = 4 is of (h/g)(4) = 81/21 = 3.86.

b) The value that is not in the domain of the division function is of x = -1.25.

In this problem, the functions that we are given are defined as follows:

To find the quotient function of h(x) and g(x), we just divide the function h(x) by the function g(x), that is:

h(x)/g(x) = [(x + 5)(x + 5)]/(4x + 5).

At x = 4, the numeric value is found replacing each instante of x by 4, hence:

(h/g)(4) = [(4 + 5)(4 + 5)]/(4(4) + 5)) = 81/21 = 3.86.

The denominator of a fraction cannot be zero, as division by zero does not exist, hence the value of x that is not on the domain of the division function is found as follows:

4x + 5 = 0.

4x = -5.

x = -5/4

x = -1.25.

It depicts horizontal linear equation, as the slope is 0.

The slope of horizontal lines is zero. Consequently, m = 0 in the slope-intercept equation y = mx + b. Y = b, where b is the y-coordinate of the y-intercept, results in the equation.

The y-coordinate of every point on a horizontal line is the same. The line's equation is y=b if two points share the same y coordinate, b. The point (0,b) is the y-intercept of the horizontal line y=b. Horizontal lines don't have an x -intercept other than the line y=0.
