Answer: Easily A.
Step-by-step explanation: All you have to do is look at the power of the tens. The one that is the least is A. Since none of the other choices are equal to or less than 10^7, A is your answer. In scientific notation, you almost always look at the 10^x first. 
 
        
             
        
        
        
Answer:
Y=-1/2x+4
Step-by-step explanation:
-The slope is -1/2 so you just plug it in where the slope would go with an x in front
-all you need now is your y-intercept which can be found by plugging in the provided info to your basic form y=mx+b
-You can take the provided point at (10,-1) and work out what the intercepts is
-1=-1/2(10)-b
-1=-5-b
4=b
 
        
             
        
        
        
In terms of X then x would be equal to -2
        
             
        
        
        
Answer:
f(-14)=-15
Step-by-step explanation:
What ever is in the parentheses after the letter (in this case it's f) will be the x value since f(x).
So 
f(-4)=5(-4)+5
Then solve.
f(-4)=-20+5
f(-4)=-15
-15
