Answer: Yes!
Step-by-step explanation:
Yes, graphite is composed of 100%carbon. With this, can we say that graphite is an element or compound of carbon? Compound is composed of two or more elements combined in a substance in definite proportions, in the form of molecules held together by chemical bonds.
Exact form: x= NEGATIVE 6/7
Answer:
( 7 , 4 )
given:
make y the subject in equation 2:
4x - y = 24
-y = 24 - 4x
y = 4x - 24
insert this in equation 1:
4x + 10y = 68
4x + 10(4x - 24) = 68
4x + 40x - 240 = 68
44x = 68 + 240
44x = 308
x = 7
solve for y:
y = 4x - 24
y = 4(7) - 24
y = 4
1) the polynomial representing the area is
2x^4 + 6x^3 - 5x^2 -7x + 24
2) the constant term is
24
3) the polynomial is a 4th degree
4) if my guess is ryt... the LEADING coefficient is the coefficient of the highest degree of X ...i.e 2
