I assume by starting value, you mean y-intercept. The y-intercept is 15
To find this, we need to use slope intercept form and the given information to find it.
y = mx + b ----> plug in the known values
9 = -3/4(8) + b
9 = -6 + b
15 = b
Therefore, the starting value is 15.
Answer:
482 scones.
Step-by-step explanation:
Given:
Cost of each scones = $1.50
Their current profits are $578.40 which is 80% of his total sales.
Question asked:
How many scones have they sold ?
Solution:
Let total number of scones sold = 
Cost of 1 scone = $1.50
Cost of scones = $1.50 
(Unitary method)
80% of his total sales = $578.40 (given)
Dividing both sides by 1.2
Thus, they have sold 482 scones.
S=15
Whatever the number of sides of a polygon,
the sum of its exterior angles is always <span>360∘</span>
Further, each pair of exterior angle and interior angle adds up to <span>180∘</span>
Hence in a polygon with s sides (or angles),
the sum of all the interior and exterior angles would be <span><span>180∘</span>×s</span>
and sum of interior angles would be <span><span>180∘</span>×n−<span>360∘</span>=<span>180∘</span><span>(s−2)</span></span>
As sum of angles is <span>2340∘</span>
Hence, <span>180<span>(s−2)</span>=2340</span> or <span>s−2=<span>2340180</span>=13</span>
and <span>s=13+2=15</span> and polygon is a Pentadecagon.
i hope u understand :)
