Step-by-step explanation:
14 students should have red hair, if that's what you're asking.
Carlos can put the blocks in this three ways:
(i) 32 large blocks and 4 small blocks.
(ii) 22 large blocks and 5 small blocks.
(iii) 12 large blocks and 6 small blocks.
The total quantity of blocks equals the number of blocks stored in the sets of blocks. Based on the information given, we derive the following algebraic expression:
,
(1)
Where:
- Quantity of small blocks.
- Quantity of large blocks.
Now we can clear
in terms of
:

(2)
From (2) we get the following combination of sets:
1) 
2) 
3)

We kindly invite to see this question on linear functions: brainly.com/question/3400735
Slope point form is y2-y1 = m(x2-x1)
so in this case the left side is -4
m is rise/run (4/8)
and lastly the term for m is -8
seems that they want it in a diff form so well just ignore all of what i just did
(3-(-1)) = 1/2(-5-3)
