Answer:

  3x -5

Step-by-step explanation:

You want the algebraic expression for "5 is subtracted from the product of 3 and a number".

"The product of 3 and a number" is represented by 3x.

Subtraction is indicated by a minus sign. When 5 is subtracted from the product, the expression is written ...

  3x -5

Solution of equation 3x² = -2x+ 4 using the quadratic formula x = -1± √13/3.

The definition of a quadratic as a second-degree polynomial equation demands that at least one squared term must be included. It also goes by the name quadratic equations. The quadratic equation has the general form ax² + bx + c = 0. where a, b, and c are numerical coefficients and x is an unknown variable. Due to the fact that the Latin word quadratum, which means "square," and the fact that the area of a square with side length x is equal to x², a polynomial equation with exponent two is referred to as a quadratic ("square-like") equation.

Given,

Equation

3x² = -2x+ 4

3x² + 2x - 4 = 0

Using quadratic formula,

x = -2 ± √2²- 4 × 3(-4)/ 2× 3

Simplifying:

x = -2 ± 2√13/6

Equations:

x = -2 + 2√13/6

x = -2 - 2√13/6

x = -1 + √13/3

x = -1 - √13/3

x = -1± √13/3

Solution of equation 3x² = -2x+ 4 using the quadratic formula x = -1± √13/3.

Answer: 8.1e+31

Step-by-step explanation:

The equation y = 2x + 4 has the following missing value: 3.

The x and y values of an ordered pair whose values, if substituted into the equation, would make it true are the answer to the given equation.

According to the Given information

If the value of x is the missing value in the solution to the equation y = -2x + 4, and the solution is (x, -2) Hence, by adding y = -2 to the equation and solving for x, the value of x can be found:

-2 = -2x + 4

Take 4 away from both sides.

-2 - 4 = -2x + 4 - 4 (subtraction property of equality)

-6 = -2x

Add -2 to both sides.

-6/-2 = -2x/-2

3 = x

x = 3

Answer:

the answer to the division problem is `1x + 6` (a polynomial).

Step-by-step explanation:

To divide polynomials, we use the long division method. Here's how we can divide x² - 36 by x - 6:

x² - 36  |

--------

x - 6

First, we divide the leading coefficient of the numerator (which is 1) by the leading coefficient of the denominator (which is 1).

We get 1 / 1 = 1 as the first coefficient of our quotient.

x² - 36  |

--------

x - 6

  1

Then, we multiply the quotient by the denominator and subtract it from the numerator.

We get (1 * (x - 6)) = x - 6, and x² - 36 - (x - 6) = x² - x - 30.

x² - 36  |

--------

x - 6

  1

      x - 6

----------

 x² - x - 30

We repeat the process, dividing the leading coefficient of the new numerator (which is 1) by the leading coefficient of the denominator (which is 1).

We get 1 / 1 = 1 as the next coefficient of our quotient.

x² - 36  |

--------

x - 6

  1

      x - 6

----------

 x² - x - 30

   1

We multiply the quotient by the denominator and subtract it from the numerator.

We get (1 * (x - 6)) = x - 6, and x² - x - 30 - (x - 6) = x² - 2x + 24.

x² - 36  |

--------

x - 6

  1

      x - 6

----------

 x² - x - 30

   1

      x - 6

---------------

x² - 2x + 24

We repeat the process one more time, dividing the leading coefficient of the new numerator (which is 1) by the leading coefficient of the denominator (which is 1).

We get 1 / 1 = 1 as the next coefficient of our quotient.

x² - 36  |

--------

x - 6

  1

      x - 6

----------

 x² - x - 30

   1

      x - 6

---------------

x² - 2x + 24

   1

We multiply the quotient by the denominator and subtract it from the numerator.

We get (1 * (x - 6)) = x - 6, and x² - 2x + 24 - (x - 6) = x² - 3x + 18.

x² - 36  |

--------

x - 6

  1

      x - 6

----------

 x² - x - 30

   1

      x - 6

---------------

x² - 2x + 24

   1

      x - 6

------------------

x² - 3x + 18

Since the degree of the new numerator is less than the degree of the denominator, we have found the complete quotient.

So, the quotient is `1x + 6`, and the remainder is `x² - 3x + 18`.

Therefore, the answer to the division problem is `1x + 6` (a polynomial).

7.5 cups of tomato paste can be made from 25 pounds and 14 cups can make 46.67 pounds.

The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.

Given, it takes 10 pounds to make 3 cups of tomato paste.

Thus, with 1 pound, number of cups can be made is equal to (3/10) cups

Thus, using 25 pounds, number of cups can be made is equal to

(3/10)*25

= 7.5 cups

3 cups of tomato paste can be made from 10 pounds

1 cup of tomato paste can be made from (10/3) pounds

14 cups of tomato paste can be made from

(10/3)*14

= 46.67 pounds

Answer:

Step-by-step explanation:

The compound interest period rate is P = Po(1±r/t)n(t)

Here,

r = .039

t = 365

The daily rate in this situation is = .039/365

The factor for 1 compounding period for a year = (1+(.039/365))365 = 1.039768317

The growth factor is = 3.9768317%

The accounts value's growth factor is 1.0000107227, and the percent change per compounding period is 0.107227%.

What is the growth factor?

The account value's growth factor is the factor by which the account value increases each compounding period. It is given by the formula:

[tex]$growth factor$ = (1 + APR /{$compounding frequency$}) ^ {($compounding frequency$ / $period$)}[/tex]

In this case, the APR is 3.9%, the compounding frequency is 365 times per year (daily), and the period is one year. Plugging these values into the formula, we get:

growth factor = (1 + 0.039 / 365) ^ (365 / 1) = 1.0000107227

The percent change per compounding period is the amount by which the account value increases each compounding period, expressed as a percentage. It is given by the formula:

percent change = (growth factor - 1) * 100

Plugging the value of the growth factor that we calculated earlier into this formula, we get:

percent change = (1.0000107227 - 1) * 100 = 0.107227%

Therefore, the account value's growth factor is 1.0000107227, and the percent change per compounding period is 0.107227%.
