Answer:
4% Sales Tax
Step-by-step explanation:
$14 is the original total and the total including tax is $14.56 meaning the tax is $.56
$.56 fits int o $14 25 times 14/.56=25
100%=$14 $.56=100%/25=4%
Meaning the Sales tax is 4%
x=5/2 or x=-4
If its parallel to y=2x-10, which has a slope of 2, the slope of the new line is 2 (the same slope).
use point slope form:
y - y1 = M (x - x1) where M is slope
y - 11 = 2( x -(-2))
y - 11 = 2( x + 2)
y -11 = 2x + 4
y = 2x +4 +11
y = 2x + 14 has a parallel slope and goes through (-2, 11)
