Answer:
- changes by 120 for each copy
- is 1800 if none are sold
Step-by-step explanation:
Let's look at the second question first.
x is the number of copies Chau sells. If he doesn't sell any copies, then x = 0. To find Chau's pay, we use x=0 in the equation, and solve for y.
120×0 +1800 = y
0 +1800 = y
1800 = y
Chau's pay when he sells no copies is $1800.
__
If Chau sells 1 copy, then his pay is ...
120×1 +1800 = y = 1920 . . . . . . . use the equation with x = 1
The increase in Chau's pay is 1920 -1800 = 120.
Chau's pay changes by $120 for each copy he sells.

Answer:
x = -0.8 and 10.8
Step-by-step explanation:
Given the equation x2 – 10x – 8= 0
Using the general formula
x = -b±√b²-4ac/2a
x = -(-10)±√(-10)²-4(1)(-8)/2(1)
x = 10±√100+32/2
x =10±√132/2
x = 10±11.489/2
x = 10-11.489/2 and 10+11.489/2
x = -1.489/2 and 21.489/2
x = -0.8 and 10.8
