Answer:
no solutions
Step-by-step explanation:
Given the 2 equations
y = - 7x + 8 → (1)
y = - 7x - 8 → (2)
Substitute y = - 7x - 8 into (1)
- 7x - 8 = - 7x + 8 ( add 8 to both sides )
- 7x = - 7x + 16 (add 7x to both sides )
0 = 16 ← not possible
This indicates the system has no solutions
Answer:
It is D, I think it’s because the letters need to be around in the same order
The answer would be 7(a - 1)
May be there is an operator missing in the first function, h(x). I will solve this in two ways, 1) as if the h(x) = 5x and 2) as if h(x) = 5 + x
1) If h(x) = 5x and k(x) = 1/x
Then (k o h) (x) = k ( h(x) ) = k(5x) = 1/(5x)
2) If h(x) = 5 + x and k (x) = 1/x
Then (k o h)(x) =k ( h(x) ) = k (5+x) = 1 / [5 + x]
