Answer:
11y + 20
Step-by-step explanation:
Given that:
Distance south = 5y miles
East = (2y + 10) miles
Final = (4y + 8) miles
Total cycle in terms of y
Take the sum of the distances :
5y + 2y + 10 + 4y + 8
11y + 20
Answer:
Not sure, but it should look like the graph below!
Step-by-step explanation:
Graph using a few selected points.
Horizontal Asymptote: y
=
0
It increases at T because the behavior increased its speed
Answer:
y = 2.00 + .10x
9.60
Step-by-step explanation:
Let y = the total fine and x = the number of days the book is overdue.
y = 2.00 + .10x
There is a 2.00 if it is overdue + .10 per day for each day
The cost of 1 overdue book at 12 days overdue
y =2.00 +.10*12
y =2+1.20
= 3.20
She has 3 books that are 12 days overdue
Multiply this by 3
3.20*3 = 9.60
Answer:
x + 4
Step-by-step explanation:
Area of rectangle= length × breadth
In this question, one length is 5x + 3 and the area is 5x^2 + 23x + 12
This means that;
5x2 + 23x + 12 = 5x + 3 (b)
Hence, to get the other length (b) = 5x2 + 23x + 12/ 5x + 3
To get the other length, we can factorize the algebraic expression;
5x2 + 23x + 12
Product: 60x^2 (20x × 3x)
Sum: +23x (20x + 3x)
Hence;
= 5x^2 + 20x + 3x + 12
Next, we find factors;
5x (x+4) + 3 (x+4)
Therefore, the factors are (5x + 3) and (x +4)
This means that the other length is (x +4)
