D:11a+8b and the other factor would be 11a-8b
Answer:
8
Step-by-step explanation:
The ratio of nurses to docters a month ago was 3:5. Now, it's 4:5. You can tell that there aren't 4 nurses because 3 => 4 is only one nurse. If you duplicate both ratios (multiply both sides by 2), you get 6:10 (for a month ago) and 8:10 (now). This is correct because 6+2=8. Hope it helps!
Y = mx+b
draw the points on a graph. x-int is (-1,0) y-int is (0,1) you notice that you go up 1 and over 1 to get from the x-int to the y-int, in the positive direction of the x-axis and the y-axis. 1/1=1, so your m=1. b is the y-int, and that is given to you...1. so the whole equation is y = 1x+1 or just y = x+1.
Answer:
I believe the answer is B
