Answer:

Step-by-step explanation:
we have

Remember that 
To predict a value for y, when x = 4
substitute the value of x in the equation
so

 
        
                    
             
        
        
        
Hello!
You put 16 in for u and 4 in for t
v = (16) + 10(4)
Multiply
v = 16 + 40
Add
v = 56
The answer is v = 56
Hope this helps!
        
             
        
        
        
Answer:
a segment cd only
Step-by-step explanation:
segment cd is the only line that passes through segment ab at a right angle
 
        
             
        
        
        
So the ratios are 5:5 and 3:5 so the fractions are 5/10 (1/2) for 7th grade and 5/8 for 8th grade
        
                    
             
        
        
        
Step-by-step explanation:
You can insert different values of x to find y
For example:
x = 4
Plug in x into the equation
y = -1/2(4) + 5
y = -2 + 5
y = 3
So your point will be (4, 3)
If you do 1 more like this, you can draw a line between them. Or you can use Desmos to graph the line.
Hope this helped you!!
