Usando algebra, veremos que cada estudiante debe aportar $5.00.

<h3>¿Cuál será el aporte de cada estudiante?</h3>

En el caso en el que hay 25 estudiantes, cada uno aporta $4.00, entonces la cantidad total que se colecta es:

25*$4.00 = $100

Ahora, en el caso de que hay 20 estudiantes, cada uno aportara una cantidad x, de tal forma que:

20*x = $100

Debemos resolver la ecuación de arriba para x:

x = $100/20 = $5.00

Es decir cada estudiante debe aportar $5.00

Under the translation T(2, -3) the point (1, 6) will become (3, 9).
seraphim [82]

Answer:

False (under assumption T(2,-3) means move it right 2 units and down 3 units).

Step-by-step explanation:

The statement is false.

T(2,-3) means move the point right 2 (so plus 2 on the x-coordinate) and down 3 units (so minus 3 on the y-coordinate).

So (1,6) will become (1+2,6-3)=(3,3) after the translation.

The point (1,12) will become (1+2,12-3)=(3,9).

If the statement were "Under the translation T(2,-3) the point (1,12) will become (3,9)", then it would be true.

Or!

If the statement were "Under the translation T(2,3) the point (1,6) will become (3,9)", then it would be true.

Find the slope of the line perpendicular to the line graphed below. MUST BE IN ITS SIMPLEST FORM.
NNADVOKAT [17]

The slope of the line perpendicular to the line seen in the picture is - 2 / 3.

<h3>How to determine the slope of a line perpendicular to another line</h3>

The slope of a function is determined by the secant line formula and is defined by the following expression:

m = Δy / Δx         (1)

Where:

  • Δx - Change in the independent variable.
  • Δy - Change in the dependent variable.
  • m - Slope of the line.

Besides, by analytical geometry, the slope of a line perpendicular to another line is equal to:

m' = - 1 / m

If we know that Δx = 2 and Δy = 3, then the slope of the line perpendicular to the line seen in the picture is:

m = 3 / 2

m' = - 1 / (3 / 2)

m' = - 2 / 3

The slope of the line perpendicular to the line seen in the picture is - 2 / 3.
