Answer:
C no es equivalente a 6/11.
Step-by-step explanation:
24/42 no es equivalente a 6/11 porque, cuando se simplifica, no es igual a este número. Si usamos el número 6 para simplificar, la respuesta a 24/42 sería 4/7, que no es igual a 6/11.
A direct variation has a constant slope, i.e. (y/x)= constant.
Both of the given two points give a slope of (y/x)=14/2=28/4=7, so the equation of the function is
y/x=7, or simply
y=7x
Answer:
w² +9w +20
Step-by-step explanation:
Multiply it out, collect terms, and write as descending powers of w.
(5+w)(w+4) = 5w +5·4 +w² +w·4
= w² +9w +20
