The value of the given expression after simplification is 12.16

Expression:        

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is called an expression or an algebraic expression.

Simplification:

The act of substituting a complex mathematical expression with a simpler counterpart is known as simplification (usually shorter).

Simplifying the given expression i.e.(2)(2.3) + (3.14)(4) - 5

⇒(2)(2.3) + (3.14)(4) - 5

⇒4.6 + 12.56 - 5

⇒17.16 - 5

⇒12.16        

⇒(2)(2.3) + (3.14)(4) - 5 = 12.16

Therefore,The value of the given expression after simplification is 12.16

Step-by-step explanation:

The piecewise function for the discounted price of the purchase is given by:

A piecewise function is a function that has different definitions, depending on the input.

For $300≤x<$1,000, the discount is of 4%, hence the discounted price is 96% of the original price, that is:

D(x) = 0.96x, 300≤x<1,000

For $1,000≤x<$3,000, the discount is of 5%, hence the discounted price is 95% of the original price, that is:

D(x) = 0.95x, 1,000≤x<3,000.

For $3,000≤x<$5,000, the discount is of 6%, hence the discounted price is 94% of the original price, that is:

D(x) = 0.94x, 3,000≤x<5,000.

For $5,000≤x, the discount is of 10%, hence the discounted price is 90% of the original price, that is:

D(x) = 0.9x, 5,000≤x.

Please check the image attached aside to see the representation of the system of inequalities. The points (x, y) = (40, 30) and (x, y) = (10, 40) are solutions of the system of inequalities.

In this question we have a system formed by two inequalities represented by linear expressions in implicit form. Now we proceed to rewritte the system into explicit form:

y ≥ (200 - 4 · x) / 6                  (1)

y < 75 - x                                 (2)

Then, the solution set of the point is represented by an area below the function (2) and equal and greater to the function (1). Finally, we proceed to graph the system of inequalities. The points (x, y) = (40, 30) and (x, y) = (10, 40) are solutions of the system of inequalities.

After 156 seconds the strands will change color at the same time again.

As strand 1 changes color every 12 seconds and Strand 2 .changes color every 13 seconds. we are provided that both strands just changed color and we need to find that After how many seconds will the strands change color at the same time again

To know After how many seconds will the strands change color at the same time again we need to find the least common multiple (LCM) of 12 second and thirteen seconds

The factors of 12 = 2*2*3

The factors of 13 = 1 *13

LCM =2 * 2* 3*13 = 156

Hence, After 156 seconds the strands will change color at the same time again

a = 1, b = 2 is a counterexample, and with that, we conclude that the conjecture is false.

Here we have the conjecture:

"For any two integers a and b, (a - b)^2 = (a^2 - b^2)"

Notice that if we find a single pair of integers a and b such that the equality in the conjecture is false, then we have found a counterexample and that is enough to conclude that the conjecture is false.

If we define=

a = 1

b = 2

Replacing that in the equation of the conjecture we get:

(1 - 2)^2 = (1^2 - 2^2)

(-1)^2 = 1 - 4

1 = -3

This is false, then a = 1, b = 2 is a counterexample, and with that we conclude that the conjecture is false.

The roots will be unchanged by multiplication by 3: 3x2 - 24x + 45

Step-by-step explanation:

Answer:

y = 3x² + 6x - 45

Step-by-step explanation:

given roots x = a and x = b then the factors are (x - a) and (x - b)

then the quadratic is the product of its factors

y = a(x - a)(x - b) ← a is a multiplier

here x = - 5 and x = 3 with a = 3 , then factors are

(x - (- 5)) and (x - 3) , that is (x + 5) and (x - 3) , then

y = 3(x - 3)(x + 5) ← expand factors using FOIL

y = 3(x² + 2x - 15) ← distribute parenthesis by 3

y = 3x² + 6x - 45

The constant of proportionality is 3 for the ratio of robins to cardinals.

We have a table:

Cardinals        Robins

5                      15

6                      18

9                       27

10                      30

We need to find the constant of proportionality.

The constant of proportionality is the ratio that relates two given values in what is known as a proportional relationship.

We know that:

Robins ∝ Cardinals

Robins = K × Cardinals

K = the constant of proportionality

15 = k (5)

k = 3

So, we get the constant of proportionality as 3.

Therefore, the constant of proportionality is 3 for the ratio of robins to cardinals.

The algebraic expression that represents the total amount of money in terms of x is:

y = 45*x + 20

Here we want to find the total value (in cents) of:

The total value will be given by the linear equation:

y = x*25 + (x + 2)*10 + (2x)*5

Where y represents the total value in cents.

Now we can simplify that equation to get:

y = x*25 + (x + 2)*10 + (2x)*5

y = x*25 + x*10 + 20 + x*10

y = 45*x + 20

From division it is possible to find x= -4.

An equation can be represented by a linear function. The standard form for the linear equation is: y= ax+b , for example, y=7x+2. Where:

a= the slope. It can be calculated for [tex]a=\frac{\Delta y}{\Delta x}[/tex] .

b= the constant term that represents the y-intercept.

For the given example: a=7 and b=2.

For solving  linear equations, you should organize variables on one side of the equation and the numbers on the other side. When a number or variables change side, its signal also is changed.

Therefore for -12x=48, you should follow the steps below

-12x=48
