Answer:

4x^2 and 5x or 4 and 5, not sure how it goes, but it's for sure 4 and 5

Step-by-step explanation:

a factor is something which is multiplied by something else soooo I'd say it's 4x^2 and 5x because they are supposed to be multiplied by whatever x is

Exercice 2: Un remorqueur tire un bateau à la vitesse de 10 noeuds. La tension du câble est de 2500N, Le câble est parallèle à l
Elza [17]

Répondre:

1 285 watts

Explication étape par étape:

La puissance est exprimée selon la formule;

power = travail effectué / temps

Puissance = Force * (distance / temps)

Depuis Vitesse = distance / temps

Puissance = Force * vitesse

Donné

Force = 2500N

Vitesse (en m / s) = 0,514 m / s

Obligatoire

Puissance

Remplacez la formule donnée;

Puissance = 2500 * 0,514

Puissance = 1,285Watts

Par conséquent, la puissance correspondante requise est de 1285 watts

Y=3xy-1, Solve for y
Ket [755]

Answer:

y = \frac{1}{3x-1}

Step-by-step explanation:

Given

y = 3xy - 1

Collect terms in y on the left side by subtracting 3xy from both sides

y - 3xy = - 1 ← factor out y on the left side

y(1 - 3x) = - 1 ( divide both sides by 1 - 3x

y = \frac{-1}{1-3x} ← multiply numerator/denominator by - 1

y = \frac{1}{3x-1}
