Let’s call the amount of pants x and the amount of shirts y.
12y + 21x = 240
y + x = 14 which could be changed to x= 14-y
now you plug it into the first equation
12y + 21 (14 - y) = 240
12y + 294 - 21y = 240
add the similar terms
12y - 21y = 240 - 294
-9y = -54
cancels the minus signs on both sides
9y = 54
y= 6
now you plug y = 6 into the equation x = 14-y
x = 14 - 6
x = 8

Last one
B.) 3.250*106 days
I figured it out!! Yay!
You take 7.8 and divide it by 24 which will get you 0.325
In order to get it match one of the options, multiply it by 10 (which will add 1 to 105!) Leaving you 3.25*106
Answer:
The slope is 1.
Step-by-step explanation:
A first order function has the following format

In which a is the slope
(6, -12).
This means that when 
So


(15. -3)
This means that when 
So


We have to solve the following system of equations:


We have to find a
In the second equation i will write as:

Replacing in the first






The slope is 1.
