Answer:
Per minute value fee would be the slope of the line.
Step-by-step explanation:
Given:
Per minute charges by the phone company = $ 0.50
Connection fee (fixed) charged by company = $ 1.0
We have to represent the total cost in terms of y and also explain the slope of the line.
According to the question:
Let the number of minutes be "x" .
And the total cost charged be "y" .
So,
The total cost = (No. of minutes)(Per minute charge) + Connection fee
Re-arranging in term of x and y.
⇒ 
⇒
...equation (i)
Slope- intercept form:
m is the slope and b is the y-is intercept.
⇒ Comparing equation (i) with the slope- intercept form.
⇒
and 
So,
The slope of the line is 0.50 which is also represented by the per minute value of the call.
Per minute value fee would be the slope of the line.
45 = 90% * x
45 = .90x
45/.90 = x
x = 50
45 is 90% of 50
Answer:
<em>x=3</em>
Step-by-step explanation:
<u>Angles and Lines</u>
We must recall:
- The sum of the internal angles of a triangle is 180°
- Two linear angles add up to 180°
The image shows a triangle and the extension of its base to form two linear angles.
Note from the triangle, angle R is what it takes to get to 180°:

From the line SQ, angle R what it takes to get to 180°. Thus:

Equating:

Subtracting 180 and simplifying:


Dividing by 19:
x=3
35/12 is the correct answer
