4 x 3 = 12 ?? I’m not sure what the question is asking to do.
Answer:
The interest rate is 10%.
Step-by-step explanation:
Interest = principal * rate * time
time is always in years. 6 month = 0.5 year
1.) 165 = 3300 * r * 0.5
2.) multiply 0.5 and 3300
165 = 1650r
3.) divde 1650 to each side
0.1 = r
0.1 = 10%
B is the Y-intercept or where the graph crosses the y-axis. they provide you with a few things which can help you figure this out. they give you the values of x and y in a table
X | Y
2 | -5
4 | -9 The difference between each Y value is 4...so, I add 4 to the -5
6 | -13 and get -1...going up another value for the X would be at 0. This leaves me with an ordered pair of (0,-1).....thus, the value of b is -1.
