Jana earns $25 per week for mowing the lawn and deposits the money into her savings account. The amount of money in Jana’s accou
nt can be represented by the equation y = 25x + 125, where x is the number of weeks she has been mowing the lawn. What does the y-intercept of the graph represent in this situation? Choose from the options below. a the amount of money Jana has after she mows 5 lawns
b the amount of money Jana earns mowing each lawn
c the amount of money in Jana's account before she began mowing lawns
d the amount of money Jana deposits into her savings account after 1 week of mowing lawns
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
x = the number of weeks she mows the lawn
y = the amount of money in Jana's savings account
y = 25x + 125
[amount of money in savings account(y) = $125 plus $25 per week(x)]
y-intercept = 125
So if x = 0 weeks and y = $125 in the savings account, $125 was already/initially in the savings account before she started earning and depositing $25 per week. Your answer is C
<span>We have the function: f ( x ) = ( x + 6 ) ( x + 6 ) = ( x + 6 )^2. This is the square of the binomial. It has only one zero ( only one x- intercept ). When f ( x ) = 0, ( x + 6 )^2 = 0. x + 6 = 0; x = - 6. Therefore point ( - 6 , 0 ) is the only x - intercept. Answer: D ) f ( x ) = ( x + 6 ) ( x + 6 ).</span>
