George is planning to save money over the next fourteen years to help with his future college expenses. His goal is to keep his money safe while earning interest. Which savings option will help him to accomplish his goal? A He should give money to his mother each month. She should put it in the family's home safe until he is ready to go to college. B He should put his money in a non-interest bearing checking account so he will have easy access to the money when he needs it. C He should save his money in a bank savings account so he can earn interest and have more money in the future. D He should put his money in a piggy bank and hide it in his room until he is ready to go to college.

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
