For her phone service, Charmaine pays a monthly fee of $15, and she pays an additional $0.05 per minute of use. The least she ha

Tamiku [17]

Step-by-step explanation:

after subtracting the monthly fee (which she has to pay, even if she does not make a single call) we have

66.9 - 15 = $51.90

for actual phone call minutes.

1 minute is $0.05

so, in the month with the lowest charge she had used

51.9 / 0.05 = 1038 minutes for calls.

since this was the minimum, for all the numbers of minutes m she used in a month we have

m >= 1038 minutes

[PLEASE ANSWER] Precalculus Question (has 2 parts)

artcher [175]

Part I

$\bf \begin{array}{l|lllllll}
x&2&\boxed{4}&6&8&\boxed{10}&12&14\\\\
y&1&\boxed{6}&11&16&\boxed{21}&26&31
\end{array}\implies 
\begin{array}{llll}
(4,6)\\\\
(10,21)
\end{array}\\\\
-------------------------------\\\\$

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 4}}\quad ,&{{ 6}})\quad 
% (c,d)
&({{ 10}}\quad ,&{{ 21}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{21-6}{10-4}$

part II

$\bf y-{{ y_1}}={{ m}}(x-{{ x_1}})\qquad 
\begin{array}{llll}
\textit{plug in the values for }
\begin{cases}
y_1=6\\
x_1=4\\
m=\boxed{?}
\end{cases}\\
\end{array}\\
\left. \qquad \right. \uparrow\\
\textit{point-slope form}$

now, the form above is the point-slope form, and that'd be the equation, you can leave it like so, or you can solve for "y", and put it in slope-intercept, same equation though.

Suatu ketika Pak Veri membeli dua karung beras untuk kebutuhan hajatan di rumahnya setelah dibawa pulang istri Pak Veri merasa b

Y_Kistochka [10]

Menjawab:

2k + 5

Penjelasan langkah demi langkah:

Mengingat bahwa:

Pembelian pertama:

Karung beras yang dibeli = 2

Tambahan kg beras yang dibeli = 5kg

Misalkan banyaknya kg dalam satu karung beras = k

Karenanya,

Pembelian pertama + pembelian tambahan

2k + 5

Oleh karena itu, ungkapan aljabar untuk Beras yang dibeli oleh Pak Veri dalam kg:

2k + 5

k diberikan dalam kg
