Answer: The amount invested at 10% was $3200.
Step-by-step explanation:
Since we have given that
Principal amount = $7200
Rate of interest are 10% and 9%.
Total interest = $680
Let the amount invested on 10% be 'x'.
Let the amount invested on 9% be '7200-x'.
According to question, we get that
Hence, the amount invested at 10% was $3200.
we will first calculate the cost of each month, then for each day and then for each period and then for each minute.
cost per month = 10750/10 = 1075
considering each month has 30 days
cost for each day = 1075/30 =
cost for each period = 1075/(30×7)
cost for each minute = 1075/(30×7×45)
=$ 0.11375
The answer is D.
3x + 2 > 14, id you plug in 5 for x, it is 3 x 5 > 14 and that is true.
10 - x < 7, If you plug 5 in, it turns into 10 - 5 < 7 and that is true.
The answer to your question is y
=

To find out the intercepts of a graph with the axes, you must substitute either y = 0 or x = 0
To find the intercept with the x-axis, we sub in y = 0, to get:
2x = 12; x = 6, so your x-intercept is (6,0)
To find the intercept with the y-axis, we sub in x = 0, to get:
4y = 12; y = 3, so your y-intercept is (0,3)
