Answer: 

Step-by-step explanation:
Let x be the number of computers Grade 3 and grade 4 has and y be the numbers of computers the rest of school has.
Then, x= Grade 3 computers +Grade 4 computers.

And y = Total computers - x

Therefore, The equations can be used to find how many computers the rest of the school has.


Answer:
- degree 4
- leading coefficient 18
Step-by-step explanation:
The degrees of the terms in the order they are written (exponent of the variable) are: 0, 4, 3, 2.
The highest degree is that of the second term, so that is the degree of the polynomial, 4.
The leading coefficient is the coefficient of that term: 18.
A. They have negative reciprocal slopes
17 = p - 3 - 3p
Add 3 to 17.
20 = p - 3p
Combine p and 3p (addition)
20 = -2p
Divide by (-2p) to find p.
Since a negative divided by a negative equals a positive, -p would turn into a positive p.
-10 = p
