Answer:

El Dr. Potter aplicó 32 vacunas de polio y 28 de sarampión.

Step-by-step explanation:

- First, the data must be taken into account to create the equations:

  •  X + Y = 60;    (Equation 1)

- Where:

 X = Number of polio vaccines and Y = Number of measles vaccines.

  •  4X + 2Y = 184;     (Equation 2)

Where for each polio vaccine there are 4 doses and for each measles vaccine there are 2 doses.

- We clear the variable that we want to find in each equation:

  • Y = 60 - X;     (And we call it equation 3)
  • Y = (184-4X) / 2;     (And we call it equation 4)

- Now both equations are equalized in terms of the same variable:

  • 60 - X = (184 - 4X) / 2

- Then X is cleared to find its value:

  • 120 - 2X = 184 - 4X
  • 4X - 2X = 184 - 120
  • 2X = 64
  • X = 32

- Now we demonstrate the value of X obtained in equation 1 or 2 to give the values ​​of Y

  • (32) + Y = 60
  • Y = 60 - 32
  • Y = 28

- Finally, both values ​​are used to see if equation 2 gives us the correct data:

  • 4 (32) + 2 (28) = 184
  • 128 + 56 = 184

- The answer is given:

Dr. Potter gave 32 polio and 28 measles vaccines.

Helppp I need the right answer quick

1. Two consecutive integers means that the values are whole numbers and they are located right after the other (eg. 2, 3).

Now, let us call the smaller value x. The consecutive value will be one greater than x, thus the larger value may be written as x + 1.

2. We know that the product of the two values is 420. Given that the smaller value is x and the larger value is x + 1, we can write this as:

x(x + 1) = 420

3. Now we can expand to get:

x^(2) + x = 420

4. Now subtract 420 from both sides to get:

x^(2) + x - 420 = 0

Therefor, the constant of the quadratic expression is -420.
