Answer:

Number of students in vans =15 and bus =46

Step-by-step explanation:

use variables for the vans and buses

let x= vans and y=buses

Now solve the 2 equations simultaneously

remember to number your equations

6x+7y=412..........1

6x+9y=504.........2

make x the subject of one equation

and label it equation 3

6x=412—7y

$x = \frac{206}{3} - \frac{7y}{6} .............3$

subs 3 into 2

$6( \frac{206}{3} - \frac{7y}{6} ) + 9y = 504$

$412 - 7y + 9y = 504$

$- 7y + 9y = 504 - 412$

$2y = 92$

$y = 46...................4$

subs 4 into 1

$6x + 7(46) = 412$

$6x + 322 = 412$

$6x = 412 - 322$

$6x = 90$

$x = 15$

Therefore there are 15 students in each van and 46 students in each bus.

Answer:

the answer is A x=4

Step-by-step explanation:

when we plug x=4 in each of the function we get the value 2

when we plug x=3 we get an undefined value

when we plug x= 2 and x=1 we get complexed values so

the answer is x=4

f(4)=1/(4-3)+1

=1/1+1

=1+1

= 2

g(4)=2√(4-3)

=2(√1)

=2(1)
