Answer:

x = 15

Step-by-step explanation:

MULTIPLY 1/4 with each number in the parentheses:

1x/2 - 7/2 = 4

ADD 7/2 to both sides:

x/2 = 15/2

MULTIPLY both sides by 2:

x = 15

Kayla went over the allotted cell phone minutes this month by 42 minutes. Her regular bill is $39.95, but this month is was $54.

Nimfa-mama [501]

$\frac{\text{ over time minutes }}{\text{ cost for overtime minute}} = \frac{42}{14.7}$

The ratio of overtime minutes to the cost of those minutes is 42 : 14.7

Solution:

Kayla went over the allotted cell phone minutes this month by 42 minutes

Therefore,

over time minutes = 42 minutes

Her regular bill is $39.95, but this month is was $54.65

Regular bill = $ 39.95

This month bill = $ 54.65

Therefore, cost for overtime minute is given by:

cost for overtime minute = This month bill - regular bill

cost for overtime minute = $ 54.65 - $ 39.95

cost for overtime minute = 14.7

Thus ratio of over time minutes to cost of those minutes is given by:

$\frac{\text{ over time minutes }}{\text{ cost for overtime minute}} = \frac{42}{14.7}$

Thus the required ratio is found

At which values does f(x)=2/3x(x-1)(x+5) have a vertical asymptote

vova2212 [387]

$f(x) = \frac{2}{3x(x-1)(x+5)} 
\\ \\ Denominator
x \neq 0,
\\ \\x-1 \neq 0, x \neq 1,
\\ \\x+5 \neq 5, x \neq -5.

It should be 3 vertical asymptote
x=0, x=1,x=-5$
