Hi there!
Let's solve this problem step by step!
The zeros of a function are the input values that produce an outcome of 0. To find this input values we must set up and solve an equation.

Set up the equation

thus

Now use the rule AB = 0 gives A = 0 or B = 0. This rule basically means that if we have a product that equals 0, at least one of the factors must be 0.
Hence, we get the following:

Finally add 8 to both sides in the right equation.

The zeros of the function are 0 and 8.
~ Hope this helps you!
1/8 is the answer when you subtract 4/8from 5/8
It looks like one row with one more dot is being added each time :)
let
x-------> the number of Lucy's orders
y-------> the number of Sam's orders
z-------> the number of Bob's orders
we know that
<u>
</u>----> equation A
-----> equation B
-----> equation C
substitute equation B and C in equation A

find z

find y

therefore
<u>the answer is</u>
the number of Lucy's orders is 
the number of Sam's orders is 
the number of Bob's orders is 
Slant angle letter c is the answer
