Answer:
This is absolute value equation so collect like terms and find X
15+5=|x|
20=|x|
since it's absolute value it's going to be 20 or -20

Answer:
1.25+√3  or 2.9821 to the nearest ten thousandth.
Step-by-step explanation:
sin 60 = √3/2,  tan 45 = 1 and cos^2 60 = (1/2)^2 = 1/4
So we get 2 *√3/2 + 1 + 1/4
= √3 +  1.25
 
 
        
                    
             
        
        
        
Answer:
y=4
Step-by-step explanation:
From the graph we can see that-
when, x=-3 ,  y=4
That is , the graph passes through   (-3 , 4)
So, 
for  x=-3 , 
we get    y=4
So, the answer is    y=4
