(f+g-k)(x) means to add the equations f(x) and g(x) then subtract k(x)

2x^2 + 3x + 4x - 9 = 2x^2 +7x -9

2x^2 + 7x - 9 - x^2 -7x = x^2 -9

The answer is : x^2 - 9

statuscvo [17]

Answer:

150 hombres juegan baloncesto.

Step-by-step explanation:

En una escuela hay 315 alumnos de los cuales 1/3 son mujeres y el resto son hombres.

Paso 1

Encontramos el número de estudiantes que son mujeres

= 1/3 × 315

= 105 mujeres.

Se nos dice que el resto son hombres. Por lo tanto, el número de hombres que son estudiantes se da como:

= 315 - 105 mujeres

= 210 hombres

Paso 2

2/7 de los hombres juegan fútbol y el resto baloncesto.

Esto significa que 2/7 de 210 hombres juegan al fútbol

= 2/7 × 210 hombres

= 60 hombres

Por tanto, 60 hombres juegan al fútbol.

Paso 3

También se nos dice que el resto juega al baloncesto.

El número de hombres que juegan baloncesto se calcula como:

210 - 60

= 150 hombres.

Por tanto, 150 hombres juegan baloncesto.

Which equations are true?<br>A: -x = -x + x + 0<br>B: -x = 0 + (-x)<br>C: None Of The Above ​
Leto [7]
Answer: B
Explanation: if you look at A and try to combine like terms, you will add the -x on the right side the the one on the left, cancelling out the x on the left. then you have 0=x+0, and unless x=0, it is not true.
With B, when you add x to the -x, you cancel it out, giving you 0=0, which is true. hope it helps!

The students at a High School earned money for an international animal rescue foundation. 82 seniors earned an average $26.75 pe
Anon25 [30]

Answer: A. $16.13

Step-by-step explanation:

Total students = 82+74+96+99 =351

Sum of earnings of 82 seniors  = $26.75  x 82= $2193.5

Sum of earnings of 74 juniors  = $12.25 x 74 = $906.5

Sum of earnings of 96 sophomores  = $15.50  x 96 = $1488

Sum of earnings of 99 freshmen  =  $10.85 x 99 = $1074.15

Total earnings =  $2193.5  + $906.5+  $1488 +$1074.15

= $5662.15

(Total earnings) ÷ (Total students )

= $5662.15÷ 351

= $16.13
