You have the formula. Put in the numbers and solve for r.
The interest earned in 4 years on 5000 is (6500 -5000) = 1500.
.. I = Prt
.. 1500 = 5000*r*4
.. 1500/20000 = r = .075 = 7.5% . . . . . . matches selection B
You could find this by doing 6 * 5 * 4, or 6 choices * 5 choices * 4 choices = total choice combinations.
6*5*4 = 120
Answer:
3h-9
Step-by-step explanation:
you can't fit it into an equation because 1, i dont a image of it and 2, you can't subtract a number from a coefficient/variable
It will take 1 minute to tub to drain to his desired level, by Rate of change.
What is rate of change?
Rate of change is used to mathematically describe the percentage change in value over a defined period of time.
Given, starting water value = 42 and desired water level = 28
Rate of change = 14 gallons.
Let x be the time,
According to question,
42-14x=28
-14x=-14
x=1
Hence, it will take one minute.

Answer:
Options (2), (4) and (6)
Step-by-step explanation:
Given system of equations is,
f(x) = x² - 5x + 7
g(x) = 2x + 1
By equating both the functions,
f(x) = g(x)
x²- 5x + 7 = 2x + 1
x² - 5x - 2x + 7 - 1 = 0
x² - 7x + 6 = 0
x² - 6x - x + 6 = 0
x(x - 6) - 1(x - 6) = 0
(x - 1)(x - 6) = 0
x = 1, 6
For x = 1,
g(x) = 2x + 1
g(1) = 2(1) + 1
= 3
For x = 6,
g(6) = 2(6) + 1
= 13
Common points (solutions) of both the functions 'f' and 'g' are (1, 3) and (6, 13).
Both the solutions lie in quadrant 1.
x-coordinate of the solution (1, 3) is x = 1.
y-coordinate of the solution (1, 3) is y = 3.
Therefore, options (2), (4) and (6) are the correct options.
