They would be putting 840 each year, so each of them will be putting 420.
N^3+5 is the algebraic expression for it.
Step-by-step explanation:
1.
1% of 500 is 5 so multiply 5 by 8 for one year. which is 40 so multiply that by 2.
1% of 500 = 5
5 × 8 = 40
40 × 2 = 80
2.
1% of 1000 = 10
10 × 5 = 50
50 × 3 = 150
3.
12 months = 6%
6/12 = 1 month
0.5 = 1 month
0.5 × 9 = 4.5 (the amount of interest for 9 months.)
800 × 4.5% = 36
4.
12 months = 7%
7/12 = 1 month ( i'll leave this in fraction form because of the decimal points.)
7/12 x 8 = 4.666667 or 4.7 rounded.
1200 × 4.7% = 56.40
Answer:
y=4x+13 or y-5=4(x+2)
Step-by-step explanation:
we know that
The equation of the line into point slope form is equal to
y-y1=m(x-x1)
In this problem we have
m=4
(x1,y1)=(-2,5)
substitute
y-5=4(x+2) ----> equation of the line into point slope form
Convert to slope intercept form
y-5=4x+8
y=4x+8+5
y=4x+13 ----> equation of the line into slope intercept form
Perimeter = 2(length + width)
16.8 = 2(3.6 + width)
3.6 + width = 16.8/2 = 8.4
width = 8.4 - 3.6 = 4.8 in
