Si a, b y r son números reales (y si a y b no son iguales a 0), ax+by = r se denomina ecuación lineal en dos variables. (Las “dos variables” son la x y la y.) Los números a y b se denominan los coeficientes de la ecuación ax+by = r. El número r se denomina constante del eje de ecuación + por = r.
Perimeter= 2l+2w
p= 2(2x)+2(x+3)
Distribute
p=4x+2x+6
Combine like terms
p=6x+6
Final answer: 6x+6
Answer:
800 meters
Step-by-step explanation:
y is inversely proportional to x is the same as y is inversely proportional to 
that means
If a wave with a frequency of x=720 kilohertz has a length of y=500 meters, then
Hence, the length of a wave y with a frequency of x=450 kilohertz is
