Answer:
Step-by-step explanation:
sum of ratio=3+6=9
Jeff invest=3/9×146,000=146000/3=48666 2/3 $
Trudy invest=6/9×146,000=292,000/3=97,333 1/3 $
6.50x+2.50y = total
with x = # of movie tickets
with y= # of bags of popcorn
Answer:
The y-intercept is -4
Step-by-step explanation:
You have your x intercept, which is 4 and your y is -4. Hope this helps :)
-2a + 3b = 9 / x 2;
-4a + 6b = 18;
Then, -4a + 6b = 18
+4a - 2b = 3
__________________(+)
We obtain 4b = 21;
b = 21/4;
-2a + 63/4 = 9;
-8a + 63 = 36;
-8a = - 27;
a = 27/8 ;
