What is the y-intercept of a line perpendicular to y= 1/2x + 6 that passes through the point (4,-3)
zalisa [80]

Answer:

(0,5)

Step-by-step explanation:

Perpendicular lines have slopes which are negative reciprocals of each other. The slope of the line y=1/2x + 6 is 1/2. The slope perpendicular to it is -2.

Using m=-2, substitute it and (4,-3) into the point slope form and simplify to find the y-intercept.

y-y_1 = m(x-x_1)\\y--3=-2(x-4)\\y+3=-2(x-4)\\y+3=-2x+8\\y=-2x+5

The equation is now in slope intercept form y=mx+b and b is the y-intercept. The y-intercept of y=-2x+5 is (0,5).

Carla has a credit card that uses the average daily balance method. For the first 15 days of a 31-day billing cycle, her balance
Advocard [28]

Answer:

Option A $29.46 is correct.

Step-by-step explanation:

Credit card's billing cycle  = 31 days

To calculate the average daily balance we must add Carla's balance from each day in the billing cycle and divide by the number of days of the month.

( Total balance × days ) / number of days of the month

(2560 × 15) ÷31 = $1238.71

Her credit card's APR is 28%  Therefore Carla charged

(1238.71 × 0.28 × 31) ÷ 365

10,752.0028 ÷ 365 = 29.4575 Rounded to $29.46

Carla charged in interest for the billing cycle is $29.46.
