There are 100 sheets of paper in the printer, and the number of sheets of paper, p, left after ,t, minutes of printing is given

zalisa [80]

P(t)=number of sheet of paper after t minutes.
p(t) will have to be equal to 0, wnen the printer use all 100 sheets of paper;
Therefore;
if p(t)=0
Then:

-8t+100=0

We solve this equation.
-8t+100=0
8t=100
t=100/8
t=12.5

Answer: the printer prints 100 sheets of paper in 12.5 minutes.

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Reflection is the flipping of a point about an axis. If a figure with point A(x, y) is reflected about the y axis, the new point is A'(-x, y)

The quadrilateral KLMN has vertices at K(-2, 6), L(-3, 8), M(-4, 4) and N(-3, 2). If the quadrilateral is reflected about the y axis, the new point is at:

K(2, 6), L(3, 8), M(4, 4) and N(3, 2)

The figure was plotted using geogebra online graphing tool.
