Answer:
(6,-7)
Step-by-step explanation:
subtract them:
-8x - 5y = -13
-4x - 5y = 11
you get
-4x = -24
so x = 6
plug x into the second equation:
-24 - 5y = 11
-5y = 35
y = -7
so your solution is (6,-7).
Answer:
F(m) = -12
Step-by-step explanation:
Given the function:
When m = 4, we substitute the variable 'm' for the number 4:

F(m) = 256 - 384 + 80 + 40 - 4
F(m) = -12
Multiply all of them together.10*9*8 and so on...
