The correct answer is (4,1).
Answer:
P= 2
Step-by-step explanation:
10/7p+13/8+15/2p=-909/56
Combine like terms
10/7p+15/2p=-909/56-13/8
20p+105p/14=-909-13*7/56
125/14p=-909-91/56
125/14p= -1000/56
125/14p*14/125= -1000/56*14/125
simplify
P= 8/4=2

35 would be positive while 40 would be negative
<span>A) -x+y=4
B) 6x+y= -8
Multiplying "A" by -1
A) x -y = -4 then adding it to B
B) 6x + y = -8
7x =-12
x = -12/7 = </span><span>-1.7142857143
y = 4 + x = </span><span><span><span>2.2857142857
</span></span></span>Did you make a typo because as you can see, the solution is not one of the 4 choices.
3. Y=2x+3
4.y=3x+18
