Answer:

y = 2x - 4

Step-by-step explanation:

10x - 5y = 20

Subtract 10x both sides

-5y = 20 + (-10x)

Divide by -5

y = -4 + 2x

y = 2x + (-4)

In the 1990s the demand for personal computers in the home went up with household income. For a given community in the 1990s, th
WITCHER [35]

Answer:

a) 0.5198 computers per household

b) 0.01153 computers

Step-by-step explanation:

Given:

number of computers in a home,

q = 0.3458 ln x - 3.045 ;   10,000 ≤ x ≤ 125,000

here x is mean household income

mean income = $30,000

increasing rate, \frac{dx}{dt} = $1,000

Now,

a) computers per household are

since,

mean income of  $30,000 lies in the range of 10,000 ≤ x ≤ 125,000

thus,

q = 0.3458 ln(30,000) - 3.045

or

q = 0.5198 computers per household

b) Rate of increase in computers i.e \frac{dq}{dt}

\frac{dq}{dt} = \frac{d(0.3458 ln x - 3.045)}{dt}

or

\frac{dq}{dt}=0.3458\times(\frac{1}{x})\frac{dx}{dt} - 0

on substituting the values, we get

\frac{dq}{dt}=0.3458\times(\frac{1}{30,000})\times1,000

or

= 0.01153 computers

Graphing Natural Exponential Functions In Exercise, sketch the graph of the function.
Mnenie [13.5K]

Answer:

Let g(x)=e^{2x-1}

View Graph

Step-by-step explanation:

Let g(x)=e^{2x-1}

find the cutting points with respect to the axes.

We can say that g(x) = y, well then y=e^{2x-1}, if x=0 then y=e^{2x-1}=e^{(2*0-1)}=e^{-1}=0.36787

with respect to x there are no cut points since it is an asymptote

To x=1 y≅2.718, x=-1 y≅0.049, x=2 y≅20.08, x=-2 y≅0.0067, this for plotting  some values
