Answer:
Step-by-step explanation:
Point-slope formula is represented by the equation . When knowing a point a line crosses through and its slope, you can write an equation in this form. Substitute the
,
, and
for real values.
The represents the slope of the line. Since we know the slope is -2, substitute -2 for
. The
and
represent the x and y values of the point the line passes through. Since the line passes through (4, -6), substitute 4 for
and -6 for
. This gives the following answer and equation:
Answer:
2 people will take 90 days to complete the same house
Step-by-step explanation:
<u><em>Given:</em></u>
T1 = 30 days
P1 = 6
T2 = x
P2 = 2
This is an inverse proportion because if there are more people, less time will be taken to complete the house and vice versa.
<u><em>So, We'll write it in the order of :</em></u>
=> T1:T2 = P2:P1
=> 30:x = 2:6
<u><em>Writing in fraction form</em></u>
=>
<em>Cross Multiplying</em>
=> 2x = 180
<em>Dividing both sides by 2</em>
=> <u><em>x = 90 days</em></u>
So, <u><em>2 people will take 90 days to complete the same house</em></u>
