8+9+10 = 27
27/3 = 9
4+5+6 = 15
15/3 = 5
This is always so, because the third number has one extra that can be added to the first to make them 3x the same numbers.
1.44 divided by 16 which is 0.09 and to check answer you take 0.09 and multiply by 15 and you get 1.44
Y=7 is just a straight horizonal line that is perpendicular to the y axis at 7
and y=1/2x+6, is in y=mx+b form where m=slope and b=yintercept so
to find the intersection, yo just find when both sentances are correct so
y=7
subsitute that into y=1/2x+6
7=1/2x+6
subtract 6 from both sides
1=1/2x
multiply both sides by 2
2=x
so the point (2,7) is the intersection
Answer:
7.)C
8.)B
9.)B
10.)D (I think)
11.)B (yet again I think)
I'm not 100% sure on the last two
hope this helped
