The best way for him to check his answer would be to simply plug in the value found for x into the equation.
4(2) - 6 = 2
8 - 6 = 2
2 = 2
The answer is $37,923
<span>y = 844.697x^2 + 3723.485x - 13,650
x - number of years
y - the annual profit
If x = 8, the annual profit y is:
y = </span>844.697 * 8^2 + 3723.485 * 8 - 13,650
y = 844.697 * 64 + 29,787.88 - 13,650
y = 54,060.608 + 16,137.88
y = 37,922.728 ≈ 37,923
Answer:
47
Step-by-step explanation:
This might be wrong but, 320.
I used the formula for simple interest which is I=Prt, thus giving me this:
I = 1000 (.016) (20)
Hope this helps at all!
Answer:
Step-by-step explanation:
<u>STU is an equilateral triangle. And:</u>
- ST = 2x - 1
- SU = 5x - 37
- TU = x + 11
<u>All sides are equal. Then take one pair and solve for x:</u>
- 2x - 1 = 5x - 37
- 3x = 36
- x = 12
<u>Substitute x to find the side length:</u>
- 2x - 1 = 5x - 37 = x + 11 = 23
