Answer:
Comic Books
a: y=-10x+90
b: He will have 10 books at the end of the seventh day.
Step-by-step explanation:
A: Take two points. The y-intercept is (0,90). The graph decreases by 10 each day.
B: Look at day 8.
Assuming you meant to write: "xy + zy"
The answer is: xy + zy = y(x + z)
The one variable that appear multiple times is: "y". There are no coefficients (other than the implied coefficients of "1"; since "1" multiplied by any number equals that very number). Since "y" appears twice, we can "factor out" a "y" ; as follows:
________________
y(x+z).
____________________
Take note of the distributive property of multiplication:
_____________________
a(b+c) = ab + ac ;
_________________
AND: a(b-c) = ab - ac.
____________________
Likewise: y(x+z) = yx +yz
= xy zy

I guess
The formula for P and B is 4P + 10B = 7
Given,
The number of batteries in a packet = 4 batteries
The number of batteries in a box = 10 batteries
Sarah bought P packets and B boxes of batteries
The total number of batteries Sarah bought = 7 batteries
We have to write an expression;
Here,
4 batteries in a packet.
Sarah bought P packets of battery.
So, she bought 4P batteries
Then,
10 batteries in a box
Sarah bought B boxes of battery
So, she bought 10B batteries
That is,
Sarah bought a total of 4P + 10B batteries which is 7 batteries
Therefore,
The formula for P and B is 4P + 10B = 7
