Answer:

x=6/7, y=-228/35

Explanation:

-4x+5y = -36 /*3

15x-3y = 32  /*5

------------------------- here we multiply both equations to get common y

-12x+15y = -108

75x-15y = 160

------------------------- then we add these two equations to eliminate the y

-12x+75x+15y-15y = 54

63x = 54

------------------------- then we get the x

x = 54/63

x = 6/7 (after we divide both with 9)

------------------------ next up, we add the value of x in first equation

-4 * 6/7 + 5y = -36

-24/7 + 5y = -36

------------------------ we leave 5y on the left side

5y = -36 + 24/7

5y = -252/7 + 24/7

-------------------------- common divider is 7 so we multiply 36*7=252

5y = -228/7

y= -228/7/5/1

------------------------- now we leave only y on the left side

y = -228*1/7*5

y = -228/35

------------------------- when dividing the fragment we multiply outer and inner

How does the structure of the cell membrane support its function?
mylen [45]

Answer:

Phospholipids form the basic structure of a cell membrane, called the lipid bilayer. Scattered in the lipid bilayer are cholesterol molecules, which help to keep the membrane fluid consistent. Membrane proteins are important for transporting substances across the cell membrane

SUNLIGHT
Mazyrski [523]

Answer:

"without light energy from the sun, photosynthesis would still occur" is completely false. Light energy is needed for the light-dependent reactions, or simply the light reactions, of photosynthesis.

"oxygen is an input into photosynthesis, carbon dioxide is an output" is also completely false. It is the opposite.

These statements are true, however:

SUNLIGHT

CARBON DIOXIDE

WATER

MINERALS

OXYGEN

PLANT SUGARS

Carbon dioxide enters the leaves through stomata (tiny holes) in the leaves.

Sunlight is an input, CO2 is an input, water is an input (taken in through the roots, transported through the veins), minerals are a collective input, oxygen is an output (produced during photolysis), and plant sugars are an output (glucose, for an example).
