then find the value of k.

Q7. For what value of m is x – 2mx + 16 divisible by x+2.​

Answer 1

Step-by-step explanation:

Q2. =8x-6x+2

=8(1)-6(1)+2

=8-6+2

=10-6

=4

Q3. p(x) =6x+5x-3x+2

p(-1) =6(-1)+5(-1)-3(-1)+2

=-6-5+3+2

=-11+5

= -6

Q4. p(y)=2y+7=0

=)2y=-7

y=-7/2

Q5. =x-1/x-1

=1

Q6. q(y) =4y+ky-y-1

q(-1)=4(-1)+k(-1)-(-1)-1=0

=)-4-k+1-1=0

=)-4-k=0

=)-k=4

=)k=-4

Sorry, I don't know Q7.

Please excuse me
