Answer:
-1.9b + 7.8
Step-by-step explanation:
3, if you do the y^2-y^1/x^2-x^1 you will get 3/1 which will be simplified to 3.
Answer:
c=9
Step-by-step explanation:
Let's solve your equation step by step:
- add 6 on both sides
- divide 1.5 from the product of 6 and 7.5 (aka 13.5)
- you will get C
- put 9 in for C.

1. 
1.5 
2.
3. C=9
1.5(9)-6=7.5
13.5-6=7.5
Answer:
No (1,5) is not a solution
Step-by-step explanation:
if you try to solve this equation with the (1,5), you lay it out like 5 = 1/4 * 1 - 7. It turns into 5 = 1/4 - 7, because 1 times anything is that same number. Then you have to add 7 to both sides so that it cancels out on the right and you get 12 on the left. So you end up with the equation 12 = 1/4. This equation is not true, so therefore (1,5) is not a solution. Hope this helps :)
