Answer:
The answer to your question is the second choice (y ≥ 1/3x - 1)
Step-by-step explanation:
Process
1.- Find two points of the graph
A (0, -1)
B (3, 0)
2.- Find the slope
m = (0 + 1)/(3 - 0)
m = 1/3
3.- Find the equation of the line
y - y1 = m(x - x1)
y + 1 = 1/3(x - 0)
y + 1 = 1/3x
y = 1/3x - 1
4.- Find the equation of the inequality
We need the upper part of the line so the inequality must be
y ≥ 1/3x - 1
You missed bringing the negative sign down from the second to third step
Answer:
<em>(8, </em><em>0</em><em>), (12, </em><em>4</em><em>), (16, </em><em>8</em><em>)</em>
Step-by-step explanation:
m =
(20, 12)
(4, - 4)
m = = 1
y - 12 = (1)(x - 20)
<em>y = x - 8</em>
y = 8 - 8 =<em> 0</em>
y = 12 - 8 = <em>4</em>
y = 16 - 8 = <em>8</em>
Let x be the number, then 60 = 40% of x & x =60/40%=60/0.4=150
then the number of which 60 represent 40% of it is 150
2) Let x be the time needed to the 16 clerks to finish the job
In one day the 32 clerks complete a portion of 32/22 of the job
In one day the 16 clerks complete a portion of 16/x of the job
So in 1 day===> 32/22 =16/x ==> x=(22*16)/32 = 11 days
