PLEASE HELP!! Alice's bank account showed a balance at the beginning of the month of $180. She spent $2.50 each day buying coffee. The amount left in her bank account, y, after x days can be represented by the equation y = 180 – 2.50x.

Describe what the y-intercept means.

a) none of these
b) The y-intercept represents the starting balance.
c) The y-intercept represents the number of days.
d) The y-intercept represents the change in the bank account per day.

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257

For the equations below which statement is true ?

The vertex of this parabola is at (-2,-3). when the x-value is -1, the y-value is -5. what is the coefficient of the squared expression in the parabola's equation?
