The y-intercept (where x = 0) of the equation is at -20.

For every 60 the x runs, the y falls by -10. Use rise over run to determine the slope of the equation.

$\frac{-10}{60} = - \frac{1}{6}$

Slope-intercept form is determined by the following equation:

$y = mx + b$

m is your slope, and b is your y-intercept.

Plug the slope and y-intercept into the equation.

$y = -\frac{1}{6}x - 20$

Which expression finds the measure of an angle that is coterminal with a 300° angle?

icang [17]

The expression that gives an angle that is coterminal with 300 is 300-720. Two angles are said to be coterminal if when they are drawn in a standard position, their terminal sides are on the same location. The expression gives an angle of 420 where when it is drawn the terminal sides are on the same location with the 300.

In 1985, there were 285 cell phone subscribers in Arlington. The number of subscribers increased by 75% per year since 1985. Fin

ANTONII [103]

Answer:

The number of subscribers in 2008 is 110,845,988

Step-by-step explanation:

The number of cell phone subscribers in Arlington, in t years after 1985, can be modeled by the following equation.

$N(t) = N(0)(1+r)^{t}$

And which N(0) is the number of subscribers in 1985 and r is the rate it increases per year, as a decimal.

In 1985, there were 285 cell phone subscribers in Arlington.

This means that $N(0) = 285$

The number of subscribers increased by 75% per year since 1985.

This means that $r = 0.75$

$N(t) = 285(1.75)^{t}$

Find the number of subscribers in 2008.

2008 is 2008-1985 = 23 years after 1985. So we have to find N(23).

$N(23) = 285(1.75)^{23} = 110,845,988$

The number of subscribers in 2008 is 110,845,988

What is the volume of a cube with length 4 inches? V=lwh

Nata [24]

The answer is: "64 cubic inches" ; or, write as: "64 in³ " .
_______________________________________________________
Explanation:

V = L * w * h ;

= (4 inches) * (4 inches) * (4 inches) ;

(since a "cube" has the same length, width, and height)

= (4*4*4) inches * inches * inches) ;

= 16 * 4 * inches³ ;

= 64 inches³ ; or, write as: "64 in³ " ; or, write as: "64 cubic inches" .
