Answer:
x < -5
Step-by-step explanation:
- 2x - 7 > x+ 8
Add 2x to each side
- 2x+2x - 7 > x+2x+ 8
-7 > 3x+8
Subtract 8 from each side
-7-8 > 3x+8-8
-15 > 3x
Divide by 3
-15/3 > 3x/3
-5 >x
40%
Step by step explanation is given above
f = 9.25 (I think but maybe I read f(4) wrong)
so f(4) means x = 4.
The new equation is
f(4) = 2x4 ^2 - 4 + 9you first do 2x4^2. The minus 4. The add 9.the answer to that is 4f = 37
Then solve
F = 9.25
