Answer: y = 5/2x + 6
Step-by-step explanation:
y - y₁ = m(x - x₁)
y - (-9) = 5/2(x- (-6))
y + 9 = 5/2(x+ 6)
y +9 = 5/2x + 15
y = 5/2x + 15 - 9
y = 5/2x +6
 
        
             
        
        
        
There are 10 portions to the circle, and 7 of the 10 are shaded. 7/10 is 70%
        
                    
             
        
        
        
f-¹(x)=
Answer:
Solution given:
f(x)=
Let f(x)=y
y=
Interchanging role of x and y
x=
doing crisscrossed multiplication
x(y+7)=-2y+2
now solve it:
xy+7x=-2y+2
keep like terms in one side
xy+2y=2-7x
take common
y(x+2)=2-7x
make a value of y
y=
So,
f-¹(x)=
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
Hi! 
So, a radical is basically a fractional power. 
Square roots are numbers to the 1/2. 
For example, the square root of 4 is just  , or 2.
, or 2. 
So for cube root, the 1/2 changes to a 1/3. 
This can then be rewritten as 
or
