Answer: Carbon
Step-by-step explanation:
Carbon is considered to be the building block of all living things as it is very important in the formation of compounds that are needed by living things to survive such as Carbohydrates and Protein and many more.
This is down to its ability to form stable compounds with other elements such as Hydrogen and oxygen both of which are present in Carbohydrates and Proteins.
Carbon exists in the Earth's crust as Carbonates in water, rocks, petroleum and living things as well especially plants and trees which release a significant amount if they are cut down.
1) C
2)A
from my calculations this should be the rounded answers
ANSWER-
B
EXPLANATION-
log6 x^6 + 2log6 y
log6 x^6 + log6 y^2
log6(x^6 y^2)
As the equation does not consists like terms we can only get x , y equations.
Step-by-step explanation:
Firstly, they are not like terms.
If the value to be is found is X then,
8x+5y=4
Now subtract 5y on both sides
8x+5y-5y=4-5y
here both positive 5y and negative 5y get cancelled
Now divide by 8
x=(4-5y)/8
If we need y value then,
subtracting both sides by 8x
5y=4-8x
Now dividing with 5 on both sides
y=(4-8x)/5 =>y=4/5 -8x/5
According to Y=mx+c
slope = m = 4/5
y-intercept = -8x/5.
Answer:
-2, 5.5
The best way to do this is to draw a graph.
