Answer: 6.5%
Step-by-step explanation:
Formula for simple interest : I = Prt , where P= principal , r= rate of interest t= time
As per given , P = $2000 , I=$ 650, t= 5 years
Substitute all theses values in the formula , we get

Hence, the required annual interest = 6.5%
Answer:
7
Step-by-step explanation:
58 divided by 8 is 7
Answer:
third graph and (3, -1)
Step-by-step explanation:
y = 2/3x - 3
y = -2x + 5
2/3x - 3 = -2x + 5
2 2/3x = 8
8/3x = 8
8x = 24
x = 3
find 'y'
y = -2(3) + 5
y = -1
The third graph is correct because it shows both a line intersecting the y-axis at -3 and the negative slope line is crossing at +5
(3,5) (1,1)
(5-1)/(3-1)
4/2
2
M=2
Then you plug in a point to find b
1=2(1)+b
1=2+b
-1=b
y=2x-1
