yan [13]

6% of $1,995 = 1995 x 0.06 = 119.70
1995 - 119. 70 = 1875.30

Sales tax = $119.70
Selling price before tax = $1,875.30

If y varies inversely as x and y=23 when x=8 find y when x=4

valina [46]

<h2>INVERSE VARIATION</h2>

EQUATION: 

$y = \frac{k}{x}$

––––––––

First, find the constant of variation k using the formula k=xy.

$23 = \frac{k}{8}$

$k = (8)(23)$

$k = 184$

––––––––

Then, find y if x is equal to four using the formula y=184/x.

$y = \frac{184}{x}$

$y = \frac{184}{4}$

$y = 46$

F(x) = x^2, g(x) = 2/3 x^2 comparison

daser333 [38]

Answer:

g(x) is a vertical compression of f(x)

Step-by-step explanation:

Equation of graph 1 : $f(x)=x^2$

Equation of graph 2 : $g(x)=\frac{2}{3}x^2$

f(x)→a f(x)

Its is case of vertical stretch or compression

Vertical stretch if |a|>1

Vertical compression if 0<|a|<1

f(x)→a f(x)

So, $x^2$ → $\frac{2}{3}x^2$

So, $a= \frac{2}{3}=0.67$

So,0<|a|<1

So,It is a case of vertical compression

So, g(x) is a vertical compression of f(x)

Franco and Marcia getting high speed Internet access at the same time. Francos provider charges $60 for installation and $42.95

In-s [12.5K]

Answer:

4 months

Step-by-step explanation:

Franco's provider = 60 + 42.95x

Marshal's provider = 57.95x

Where,

x = number of months

Equate both charges

Franco's provider = Marshal's provider

60 + 42.95x = 57.95x

Subtract 42.95x From both sides

60 + 42.95x - 42.95x = 57.95x - 42.95x

60 = 15x

Divide both sides by 15

60 / 15 = 15x / 15

4 = x

x = 4 Months

Franco and Marshal would have paid the same amount for high-speed Internet service after 4 months
