Answer:
The sale price is $8.4915
Step-by-step explanation:
Consider the provided information.
The local drugstore is offering 15% off the normal price for a 16-pack of AAA batteries.
That means customer needs to pay 85% of the normal amount.
The price of 16-pack of AAA batteries is normally $9.99
Calculate the 85% of 9.99
Hence, the sale price is $8.4915

Answer:
Solving the inequality we get
Option D is correct option.
Step-by-step explanation:
We need to solve the inequality and find value of x
Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.
Adding 2 on both sides
Now, we will divide 3 on both sides
So, we get x < 2
Solving the inequality we get
Option D is correct option.

we have
substitute
<em>step 2</em>
Find the equation of the line with negative slope
take the points (0,40) and (8,20)
<em>Find the slope</em>
The formula to calculate the slope between two points is equal to
substitute the given values
simplify
Find the equation of the line in slope intercept form
we have
substitute
step 3
Find the solution of the system
we know that
The solution of the system of equations is the intersection point both graphs
The intersection point is (6,25) ----> see the graph
therefore
The ordered pair (6,25) is a solution to both and
