Anton [14]

Answer:

= -1/2

Step-by-step explanation:

We can use the slope formula

m = (y2-y1)/(x2-x1)

= (11-10)/(8-10)

= 1/-2

= -1/2

zepelin [54]

46.6 feet

Step-by-step explanation:

P = 2ℓ + 2w

P = 2(ℓ + w)

P = 2(15.5 + 7.8)

P = 2(23.3)

P = 46.6 feet

Given: f(x) = x + 2 and g(x) = 3x + 5 <br> f (x)/g (x) =

evablogger [386]

For this case we have two functions of the form y = f (x). We must find the quotient of the following functions:

$f (x) = x + 2\\g (x) = 3x + 5$

So, we have by definition:

$\frac {f (x)} {g (x)} = \frac {x + 2} {3x + 5}$

Answer:

$\frac {f (x)} {g (x)} = \frac {x + 2} {3x + 5}$

with 3x + 5 different from zero, so that the function is defined
