Answer:
B. $79 + 0.1($79)
Step-by-step explanation:
Given that;
the shipping cost for an order = 1/10 multiply by the cost of the items bought;
i.e. 
where
x = cost of items ordered for.
This implies that:
x + 0.1x
The objective is to determine the expression for the total cost of an order which is $79
x = 79
Then, the total cost of an order is
$79 + 0.1($79)

= 3(3 - 2r)
Step-by-step explanation:
sorry sorry ^$£%£$¥#^÷£=₩€%¥=£=;÷¥÷¥9=
To answer the question we make the sum on the left side of the equation:
Since both sides are exactly the same. this equation is always true.
A linear equations is y= mx+b
m=slope
b= y- intercept, to help me think of what b is I try to figure out where a point is on the y axis so (0,x) that would be your point on the y- axis
:) hope this helps, if you have any questions please ask
