Answer:
2x-y=8
Step-by-step explanation:
Equation of a line y-y1 =m(x-x1)
Given m=2, x1=7, y1=6
y-6 = 2(x-7)
y-6 = 2x-14
2x-y = 8
The value of f(5) is -37
<em><u>Solution:</u></em>
<em><u>Given function is:</u></em>
We have to find the value of f(5)
To find the value of f(5), we have to substitute x is equal to 5 in given function
Plug in x = 5 in f(x)
Thus value of f(5) is -37
<span>0.121212
</span><span>0.121212/1
</span><span> 0.121212 × 10 × 10 × 10 × 10 × 10 × 10 = 121212
</span><span>1 × 10 × 10 × 10 × 10 × 10 × 10 = 1000000
</span><span>121212 / 1000000
</span><span>121212/1000000
</span><span>30303/250000
</span>
0.121212 as a fraction in simplest form is <span> 30303/250000. </span>
They charge $30 per month as a base so that is y
They also charge $0.25 per text message, this is x
so $0.25x+$30y=$59.50
first subtract 30 from both sides to get x alone
$0.25x=$29.50
To find amount of text messages sent, we have to divide
$29.50/$.25
29.50/.25=118
This person sent 118 text messages
