-g(-2) is 10     
<u>Step-by-step explanation:</u>
Step 1: 
Given g(x) = 3x - 4. Find g(-2).
⇒ g(-2) = 3 × -2 - 4 = -6 - 4 = -10
Step 2: 
Find -g(-2) 
⇒ -g(-2) = -(-10) = 10

OK, like I explained in the last one KCF, (Keep Change Flip) so our problem is: 
 8/7÷5/8 So lets Keep 8/7 and change the divide sign to multiplication sign. and then for Flip you flip 5/8 to 8/5. So now our real problem is: 8/7*8/5= (8*8=64) and (7*5=35). So we have 64/35, now you just need to change this improper fraction to a proper one... message me if you have any trouble :)
