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:
The value of the expression = 200
Step-by-step explanation:
The given expression is 
Using the low of exponent 
So, the expression =

<u>So, The value of the expression = 200</u>
No, it is not a function....for it to be a function, it cant have any repeating x values...they all have to be different....they can have repeating y values, just not the x ones.....also, it does not pass the vertical line test
So basically
what percent (x%) is (=) 88 (88) out of (88/) 106 (106)
x%=88/106
x%=0.83
percent means partst out of 100
x%=x/100
x/100=0.83
multiply both isdes by 100
x=83
83%
