Answer:
<u><em>(x+5) is not a factor of f(x)</em></u>
Step-by-step explanation:
Step 1 : we solve the equation x +5 = 0
x + 5 = 0 then x = -5
Step 2: we plug in -5 into f(x)
If we get zero then x+5 is a factor of f(x)
If we get a number other than zero then x+5 is not a factor of f(x)
Calculation:
f(-5) = (-5)³ − 4(-5)² + 3(-5) + 7 = - 233
Since we got -233 and not 0
Therefore ,(x+5) is not a factor of f(x)
Answer: i think 4
Step-by-step explanation:
Answer: He had 14 more touchdowns than he did fumbles.
Step-by-step explanation:
Step 1. Ok, so we need to see how many times 9 will divide into 18.
18/9=2.
Step 2. So now that we know that 9 goes into 18 two times and we know he has two fumbles for every 9 touchdowns we can multiply 2 by 2 to find out how man fumbles he had.
2*2=4
Step 3. Now to find out how many more touchdowns than fumbles he had we need to subtract his fumbles from his touchdowns.
18-4= 14. So, now we know he had 14 more touchdowns than he did fumbles.
Hope this helps!
Se escribe una equacion y se resolve.
Vamos a usar x para representar el peso de la piedra.
En en platillo que tiene la piedra, el peso total es: x + 1/9 + 2/3
En el otro platillo: 1/2 + 1/3
La balanza esta equilibrada por eso los pesos en los platillos son iguales.
x + 1/9 + 2/3 = 1/2 + 1/3
x + 2/18 + 12/18 = 9/18 + 6/18
x + 14/18 = 15/18
x = 1/18
Respuesta: La piedra pesa un octavo de kilogramo.
