Answer:
Option C. linear: slope = -5, y-intercept = 50
Step-by-step explanation:
Let
b ----> is the automatic decrease on the gift card balance
m ----> is the number of months beyond two years
we know that
The equation of the line into slope intercept form is equal to
where
m is the slope
b is the y-intercept
In this problem the linear equation that represent this situation is
---> equation of the line into slope intercept form
so
The slope is -5
The y-intercept is 50
A = base * height
A = 10 *17
A =170
170 is the correct answer
D, the first equation of the piece wise function is linear, all linear is one is to one function, and the second is essentially a log
Answer:
(3, -5)
T=(0,6) Midpoint = (3, -2)
use the Midpoint formula:
(X1 + X2)/2=X
(Y1 + Y2)/2=Y
(0 + X2)/2=3
X=3
(6 + Y2)/2= -2
3 + Y2 = -2
Y= -5
