4.Find three consecutive integers such that the difference of double the largest number and triple the smallest number is -44. F
Taya2010 [7]

Solving a linear equation, we will see that the 3 numbers are:

48, 49, and 50.

<h3>How to find the 3 numbers?</h3>

3 consecutive integers can be written as:

x, x + 1, x + 2

Here we know that 2 times the largest number minus 3 times the smallest one is -44, then:

2*(x + 2) - 3x = -44

We can solve that linear equation for x:

2x + 4 - 3x = -44

(2 - 3)x = -44 - 4

-x = -48

x = 48

Then the 3 numbers are:

  • x = 48
  • x + 1 = 49
  • x + 2 = 50

What is the solution of this system of linear equations?<br><br> 3y = x + 6<br><br> y – x = 3
iris [78.8K]

Answer:

x=  −3 /2  and y=  3 /2

Step-by-step explanation:

x=  −3 /2  and y=  3 /2  because

3y=x+6

3y+−x=x+6+−x(Add -x to both sides)

−x+3y=6

−x+3y+−3y=6+−3y(Add -3y to both sides)

−x=−3y+6

−x /−1  =  −3y+6 /−1

(Divide both sides by -1)

x=3y−6

Step: Substitute3y−6forxin−x+y=3:

−x+y=3

−(3y−6)+y=3

−2y+6=3(Simplify both sides of the equation)

−2y+6+−6=3+−6(Add -6 to both sides)

−2y=−3

−2y/−2 = −3/−2

(Divide both sides by -2)

y=3 /2

Step: Substitute

3

2

foryinx=3y−6:

x=3y−6

x=3( 3 /2)−6

x = −3/2

(Simplify both sides of the equation)

Therefore the answer is

x=  −3 /2  and y=  3 /2

I hope this helped you.

Kim owns a start-up business that creates software apps. The graph shows her business's revenue function. What is the correct
BaLLatris [955]

The business can turn a profit by cutting costs.The sum of the units sold times the price per unit is the revenue.Multiply the output level by the pricing function to get the revenue function.

How can the business save expenses?

  • Total revenue is important because it gives businesses a high level understanding of the relationship between pricing and consumer demand for an additional unit of product at any given time. The total revenue formula is simply: TR = P * Q (Total Revenue = Price * Quantity Sold)

changing the personnel.

  • using less expensive substitute raw materials.
  • enhancing the pace of production.
  • Profit for a business is the amount of income that remains after all expenses are paid.
  • The profit would increase if these costs were decreased because less income would be needed to pay for manufacturing costs.
  • production crew salaries and raw materials
  • The entire income generated from the sale of x units of the product is represented by the revenue function R(x).
  • The total profit made from producing and selling the x units of the product is represented by the profit function, P(x).
  • Price of goods or services divided by the quantity or number of clients equals revenue.
  • For instance, if a business sells 10 computers for $50,000 each, it may figure out its gross income using the following formula:Gross revenue = ₹50,000 × 10 = ₹500,000.

Right triangle XYZ is drawn with a 23° angle. For right triangles with an angle of 23° the ratio of the leg adjacent the 23° ang
Alika [10]

Answer:

50

Step-by-step explanation:

In a right angled triangle :

Ratio of the leg Adjacent an angle to the hypotenus can be obtained using the Cosine trigonometric ratio

For an angle of 23° and and adjacent leg of 46

Cos 23 = adjacent / hypotenus

Adjacent / hypotenus = 0.92

46 / hypotenus = 0.92

Hypotenus = 46 / 0.92

Hypotenus = 50
