1 shirt costs $21.45 before sales tax
Answer:
$30
Step-by-step explanation:
because we know that "1 liter cost(s) $12" we can multiply 12 by 2.5 (the amount we need to know) to get $30
y = 8-5x
Step-by-step explanation:
When two lines are parallel, it means their gradients are the same.
from the given equation
y = 9-5x
and comparing with the general equation of a line
y = mx+c, where m is the gradient, and c is the <em>y-intercept, </em>
m = -5
you can form a line parallel to that using the points (0,8)
(y-8)/(x-0)= -5
this would give you
y = 8-5x
The rate of change or slope is 6 inches or half a foot per year. The initial value, or y intercept is 7 ft. Plug this into mx+b form to get y=.5x+7
