Y = -1/2x + 4
X + 2y = -8
Replace y in the second equation with the first one:
X + 2(-1/2x +4)=-8
Simplify:
X -X +8 = -8
Simplify:
8 = -8
Subtract 8 from both sides:
0 = -16
This is a false statement, so there are no solutions.

Answer:
y = -(3/7)x + 2
Step-by-step explanation:
(see attached)
recall that the slope-intercept form of a linear equation is
y = mx + b
where m = slope = given as -(3/7)
and b = y-intercept = 2
substituting these values into the eqation:
y = mx + b
y = -(3/7)x + 2
You would write it as (1/10^12)
any negative exponent does the same thing
ex: x^-1 turns into (1/x^1)
Answer:
D. 33.60
Step-by-step explanation:
A $40 shirt at a 20% discount would be $32. However, once a 5% tax is taken into account, the total cost would be $33.60.
