Answer:

y = x/x+3 is a rational function

rational functions are such that could be expressed as the division of one function by another

For example;

f(x) = g(x)/h(x)

is a rational function

Which is an equation for the line contains (1,2) and has the slope of 4

spin [16.1K]

The slope is 4. That eliminates the first two answers

Y-y1=m(x-x1)
Y-2=4(x-1)
Y-2=4x-4
Add 2 to both sides
Y=4x-2

Answer:

65.3%

Step-by-step explanation:

what we want: p(2)+p(3)+p(4)

$P(2)={5\choose2}*.4^2*.6^3\\P(3)={5\choose3}*.4^3*.6^2\\P(4)={5\choose4}*.4^4*.6\\P(2)+P(3)+P(4)= .6528$

which equal 65.28%

which rounds to

65.3%
