Answer:
C= 25n+100
Step-by-step explanation:
Let's see what's in the graph :
- the image of 4 is 200 C(4)=200
- C(2)= 150
let m be the slope of this function :
- m=
=25
The first value in the graph is 100 wich is c(0)=100
- so the equation is : c=25n+100
Based on the given conditions, formulate: 200x3/15/4
600/15x4
600/60
Answer is 10
June: 30-6=24
July: 31
August:31
September:30
October: 8
Total=24+31+31+30+8=124 days
Discount period:
The period of time between the date a bill of exchange is drawn and the date on which payment is due.
So discount period = 200-124=76 days
He knows he made a mistake so quickly because he substitutes 5 for x in 3x - 7 = x/2
<h3>How did he know so quickly that he made a mistake?</h3>
The equation is given as:
3x - 7 = x/2 + 9
The solution is given as:
x = 5
To quickly know he made a mistake, we substitute 5 for x in 3x - 7 = x/2 + 9
So, we have
3 * 4 - 7 = 5/2 + 9
Evaluate
12 - 7 = 2.5 + 9
Evaluate the like terms
5 = 11.5
The above equation is false.
Hence, he knows he made a mistake so quickly because he substitute 5 for x in 3x - 7 = x/2
