Answer:
see the explanation
Step-by-step explanation:
we have
<em>Felicia</em>

Apply distributive property


Combine like terms

Let 
a ----> the missing term with coefficient x in Gregory's expression
b ----> the missing constant  term in Gregory's expression
so

equate Gregory's expression to Felicia's expression

so
 ----->
 ----->
 ------>
 ------> 
so
 Gregory's expression is

therefore
The missing terms are 2 and -x
 
        
             
        
        
        
Answer:
3
Step-by-step explanation:
substitute x = 4 , y = 6 into the expression
y - (5 - (x - y))
= 6 - (5 - (6 - 4))
= 6 - (5 - 2))
= 6 - 3
= 3
 
        
             
        
        
        
F(x)=-2x^3-5
f(-2)=2(-2)^3-5
f(-2) = 2(-8)-5
f(-2)= -16-5
f(-2)=-21
(-2,-21)
g(x)=-3x+2
g(7)=-3(7)+2
g(7)=-21+2
g(7)=-19
(7,-19)
