Step-by-step explanation:
4) 3x-2 =0
3x= 2
X= 2
3
therefore 2 is the zero of the polynomial
3
if you replace X with 2 and solve the sum you will
3 get zero
7) the degree is 1
8) the points (-3,-7) lie in the 3rd quadrant
9)2x+3y = k
2(3) + 3(2) = k
6+6=k
12=k
therefore k =12
10) Probability= no. of events
no. of total events
= 2 ( no.of girls )
7 ( total children )
