Answer:
<h2>
1.5</h2>
Step-by-step explanation:
We are given two points. Let the points be A and B
A ( 8 , -2 ) ------> ( x1 , y1 )
B ( 12 , 4 ) ------> ( x2 , y2 )
Now, let's find the slope of the given points:

plug the values

When there is a ( - ) in front of an expression in parentheses , change the sign of each term in the expression

Subtract the numbers

Add the numbers

Reduce the fraction with 2


Hope this helps..

X=5
7(5)-8=35-8=27
3(5)+12=15+12=27
        
             
        
        
        
You just divided 1/2 (.5) by 10 which is .05. so the answer is 0.05 gallons
        
             
        
        
        
4000.0093979 = 63.2456275
-15999998
= 8.7
Then you get 50
 
        
             
        
        
        
Answer:
b = 2a - 2
Step-by-step explanation:
Turn the words into an algebraic expressions. so Andrea's (b)  is (=) two years less (-2) than (flips the expression so place this first ->) twice (times 2) her age (a) So b = 2a -2
