how long will it take 14 machines to complete the task, given that 8 machines can complete the same task in 7 days?
torisob [31]

Answer:

4 days

Step-by-step explanation:

If 8 machines can complete a task in 7 days, how long will 14 machines take?

So, it is obvious that if the number of machines increases, the number of days taken to complete the task decreases; thus proving that this is an indirect / inverse proportion.

Let's take <em>x</em> as the number of days we need to find out.

 8 machines : 7 days

14 machines : <em>x</em> days

14 × <em>x </em>= 8 × 7

14<em>x </em>= 56

x = \frac{56}{14}

x = 4

Identify the values a, b, and c is the first step in using the quadratic formula to find the solution(s) to a quadratic equation
zlopas [31]

The values are a = 7, b = -9, c = -18.

<u>Step-by-step explanation:</u>

The given quadratic equation is 7x^{2} - 9x = 18

The general form of the quadratic equation is ax^{2} + bx + c = 0

where,

  • a is the coefficient of x².
  • b is the coefficient of x.
  • c is the constant term.

Now, you have to modify the given quadratic equation similar to the general form of quadratic equation.

So, bring the constant term 18 to the left side of the equation for equating it to zero.

⇒ 7x^{2} - 9x - 18 = 0

Compare the above equation with general form ax^{2} + bx + c = 0

⇒ a = 7

⇒ b = -9

⇒ c = -18

Therefore, the values of a, b, and c are 7, -9 and -18.

Whitepunk [10]

The answer would be 25 because all of the others are prime numbers, meaning they can only be divided by themselves and 1. So it would be C.
