Answer:
No
Step-by-step explanation:
11. Correct
11a. a is the number of accessories bought
12. 32 = 3.5a + 25
7 = 3.5a
a = 2
12a. cost of the bear
13. correct
13a. f(-1)=8
Answer:
19
Step-by-step explanation:
4(4)+3
16+3=19
For the first equation, I put it in y=mx+b form, so y=-3x-9
the second one is x=4

M=2 or m=-3 hope this helps
In the problem, the first equation should be represented like this base on the variable given in the problem:
20p + 9t = 44.4
with that equation, the second equation would is given by this formula, in response with the additional number of paperback and textbook
21p + 14t = 51
to get the system equation in getting the mass of each variable, you should subtract the two equation to simplified the formula.
20p + 9t = 44.4
- 21p + 14t = 51
-------------------------
p + 5t = 6.6 // this is the system equation that could be use in getting the mass of each object
