Answer:
the (x, y) pair solution to the system is: (-2, -4)
That is x = -2 and y = -4
Step-by-step explanation:
I presume there is a variable y missing in the first equation, and in fact the system looks like:
(1/2) x + (3/2) y = - 7
- 3 x + 2 y = -2
In such case, we proceed to multiply both sides of tye first equation by 6
6 (1/2) x + 6 (3/2) y = - 42
3 x + 9 y = - 42 and we add term by term this equation to the second one, so as to cancel out the term in x:
3 x + 9 y = - 42
- 3 x + 2 y = -2
_____________
11 y = - 44
divide both sides by 11 to isolate y
y = -44 / 11 = -4
Then with the value y = -4, now we replace it in the second equation to solve for x:
- 3 x + 2 y = - 2
- 3 x + 2 (- 4) = -2
- 3 x - 8 = - 2
add 8 to both sides
- 3 x = 6
divide both sides by (-3) to isolate x
x = 6 / (-3) = - 2
Therefore the (x, y) pair solution to the system is: (-2, -4)
That is x = -2 and y = -4

A certain animal gets food from another animal without killing it. Identify the type of organism.
(A) Saprophyte
(B) Carnivore
(C) Parasite
(D) Autotroph
Answer:
The correct answer is C. Parasite.
Step-by-step explanation:
Parasitism describes the phenomenon within the animal and plant world that an organism or virus (parasite) misuses a usually considerably larger organism of a different species as a host. The host serves the parasite for food supply (mostly in the form of blood or other body secretions) and in some cases also as a long-term habitat. The host's health is damaged by the parasite, but usually remains alive. The consequences of parasitic infestation range from sting or bite injuries from massive physical complaints to serious infectious diseases and even death in extreme cases. The best known and most widespread human parasites are human lice, mosquitoes and various types of ticks and worms.
