Answer:
h(-2) = 13
h(5) = -1
Step-by-step explanation:
Given the function
h(x) = -2x + 9
Evaluating at x = -22
substitute x = -2
h(-2) = -2(-2) + 9
h(-2) = 4 + 9
h(-2) = 13
Therefore, 
Evaluating at x = 5
Given the function
h(x) = -2x + 9
substitute x = 5
h(5) = -2(5) + 9
h(5) = -10 + 9
h(5) = -1
Therefore, 
 
        
             
        
        
        
I am going to assume ‘centimetre’ was a typo. 
A^2 + B^2 = C^2
C^2 - A^2 = B^2
32 = B^2 
Square root both sides 
B = 5.7m high 
The ladder will reach 5.7 meters high
        
             
        
        
        
Answer:
Pass the number 5 to the other side with te opposite sign in order to leave the x alone
it would be 
-3x = 23-5
Then you divide by -3 and thats ur answer
