Answer:
-13/30
Step-by-step explanation:
I used KCC. It is a method when you<u> keep you 1st # the same</u>, <u>change subtraction to addition</u> and then <u>change the last # to its opposite.</u> So after KCC, the equation would be -7/10 + 4/15
 
        
                    
             
        
        
        
Answer:
1. Reflection across the x-axis
2. Translation 6 units to the left and 1 unit up
Step-by-step explanation:
The quadrilateral ABCD has its vertices at points A(3,5), B(6,5), C(4,1) and D(1,1).
1. Reflect quadrilateral ABCD across the x-axis. This reflection has the rule:

then

2. Translate quadrilateral ABCD 6 units to the left and 1 unit up. This translation has the rule:

then

 
        
                    
             
        
        
        
Answer:
h = 7.333....
Step-by-step explanation:
Formula is A = 1/2h(b1+b2)
Area 77 determine the height
77=1/2h(14+8)
77 = 1/2h(22)h
77/10.5 = 10.5h/1.5
solve for h = 7.333....
