If you apply the linear combination method to the system like:
<span>4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3
2x = 18
Then you can be sure that the solution of all this system is: (9,3). Hope this si what you were looking for</span>
The answer to the question is d
Answer:
29/14
Step-by-step explanation:
9- -20 / 9 - -5 = 29/14 a parallel line will have the same slope so. 29/14
Answer:
p = 9 when q = 5.
Step-by-step explanation:
p is inversely proportional to the square of q
This means that:

In which k is a constant multiplier.
p is 25 when q is 3
We use this to find k.



So

Determine p when q is equal to 5.

p = 9 when q = 5.
