Answer:
The midpoint is
( (x1+x2)/2, (y1+y2)/2)
Step-by-step explanation:
To find the x coordinate of the midpoint
(x1+x2)/2
To find the x coordinate of the midpoint
(y1+y2)/2
The midpoint is
( (x1+x2)/2, (y1+y2)/2)
Answer:
The expression can be rewritten in 
form as following:
⇒ 
where 
Step-by-step explanation:
Given expression:
To rewrite the expression in the form of .
Solution:
By property of exponents :
<em>So, we can apply this property to the given expression.</em>
We have:
⇒
The above expression is in the form of where
F(x) = 2 - 3x.....f(-4) means u r subbing in -4 for every x
f(-4) = 2 - 3(-4)
f(-4) = 2 + 12
f(-4) = 14
