I believe that b<span>. y= -1/2x+3 , y= 2x-3 is the correct answer</span>
Answer:
can u wrote this question in english .Because I don´t understand this languages
So for the first one it is (x-3)(x+3) this is because it is a difference of squares so you square root the 9 and the minus you do both +and - in order to keep up the -9
The zeros are:x=3 and x=-3 ( this is because you change the sign in the bracket
the others should be pretty simple to do for number 2 its a complex
the third is a simple trinomial
and fourth is simple trinomial as well
1. 38-19= 19.
2. 19+12=31.
31 is your answer.
Convert to fractions in 8ths 1/4=2/8. 12×8=96 +2=98 . 15×8=120 +1=121. so (121/8) - (98/8) = 23/8= 3 and 2/8 or 3 and 1/4
