1 answer:
Step-by-step explanation:
According to question, the initial value, the y-intercept is b = 8 and the rate of change, the slope is m = 2.
<u>This gives us the equation:</u>
- y = 2x + 8
<u>Plot the y-intercept (0, 8) and one more point:</u>
- x = 1 ⇒ y = 2+ 8 = 10
Connect the points to get the line.

<u>Answer: </u>
Physliis invested 32000 dollar at 5% interest rate and 34000 dollar at 7% interest rate.
<u>Solution:</u>
Let Phyllis invest ‘x’ dollar at 5% per year and (66000-x) dollar at 7% per year.
We know,
In the question it is given that Simple interest earned from both the investments at the end of the year is $3980.
Using the given below equation, we will try to find out the investments at each rate.
x = 32000
We can calculate amount for 7% interest rate by,
(66000-32000) =34000
Thus Phyllis invested 32000 dollar at 5% interest rate and 34000 dollar at 7% interest rate.
