Jada opens a savings account with a deposit of $800. the bank will pay her 4 3/4% interest per year. a. how much interest will jada receive at the end of 1⁄2 year? b. how much interest will jada receive at the end of 1 year? .

Simple Interest formula is :  , where I = Amount of interest, P= Principal amount, r = rate of interest in decimal and t = time duration in year.

Given in the question that,  P = $800 and r = % = 4.75% = 0.0475

a.  For t = year ....

So, Jada will receive $19 interest at the end of 1/2 year.

b.   For t = 1 year ....

So, Jada will receive $38 interest at the end of 1 year.

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
