The phone company Ringular has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of mon

ivanzaharov [21]

Answer:

The slope is $0.35/min and it gives the cost per minute of the phone used.

Step-by-step explanation:

We can model this situation with a linear equation of the form

$y =mx+b$

where $y$ is monthly cost, $x$ is the number of minutes, $b$ is the flat monthly fee, and $m$ is the slope of the equation, or in our case, the amount of money charged per minute.

The slope $m$ is

$m= \dfrac{\$372.5-\$131}{990min-300min}$

$m = \$0.35/min$ ,

in other words, the phone company charges $0.5 per minute.

With the slope in hand, the linear equation becomes

$y =0.35x+b$ ,

and we can find the monthly fee $b$ from that fact that for 300 minutes the cost is $131:

$\$131 = 0.35(300min) +b$

$b = \%26$ .

Therefore,

$y = 0.35x+26$

where the slope if the equation give the cost per minute of the phone used.

What is the quotient of StartFraction 7 Superscript negative 1 Baseline Over 7 Superscript negative 2 Baseline EndFraction? Star

Komok [63]

The quotient of the number given number 7 Superscript negative 1 Baseline Over 7 Superscript negative 2 Baseline is 7.

<h3>What is the quotient?</h3>

Quotient is the resultant number which is obtain by dividing a number with another. Let a number a is divided by number b. Then the quotient of these two number will be,

$q=\dfrac{a}{b}$

Here, (<em>a, b</em>) are the real numbers.

The number StartFraction 7 Superscript negative 1 Baseline Over 7 Superscript negative 2 Baseline EndFraction, given can be written as,

$\dfrac{7^{-1}}{7^{-2}}$

Let the quotient of this division is n. Therefore,

$n=\dfrac{7^{-1}}{7^{-2}}$

A number in numerator of a fraction with negative exponent can be written in the denominator with the same but positive exponent and vise versa. Therefore,

$n=\dfrac{7^{2}}{7^{1}}\\n=7$

Hence, the quotient of the number given number 7 Superscript negative 1 Baseline Over 7 Superscript negative 2 Baseline is 7.

To convert 12 yards to inches, you would use the ratio .36inches/1 yard true or false ?

Taya2010 [7]

False. It's 36 not .36 and you would just do 12x36 since 36 inches is 1 yd. But if you want to make it complicated just do 12/1 times 36/1 which still equals 432.

Shtirlitz [24]

Answer:

A) is your answer

Step-by-step explanation:

Multiply the 2x by 9x

then you take the second variable in the second equation and mulitply it by 9x. giving you 98 x squared

THEN you take 9x times Negative 3 and get -87
