Answer:
y=2x+4
Step-by-step explanation:\solving for the slope you get (12-8)/(4-2)=4/2=2
solving for the y intercept you subtract 4 from 8 because 2*2 is 4 and (2,8) is 2 x values away from the y intercept so 8-4=4 so the y intercept is 4 
so y=2x+4

We know that the area of a circle in terms of π will be πr². However the area with respect to the diameter will be a different story. The first step here is to find a function relating the area and diameter of any circle --- ( 1 ) 
For any circle the diameter is 2 times the radius,
d = 2r
Therefore r = d / 2, which gives us the following formula through substitution.
A = π(d / 2)² = πd² / 4
<u>Hence the area of a circle as the function of it's diameter is A = πd² / 4. You can also say f(d) = πd² / 4.</u>
Now we can substitute " d " as 4, solving for the area ( A ) or f(4) --- ( 2 )
f(4) = π(4)² / 4 = 16π / 4 = 4π - <u>This makes the area of circle present with a diameter of 4 inches, 4π.</u>
 
        
             
        
        
        
Answer:
3.
Step-by-step explanation:
Implicit differentiation:
x^2 y + (xy)^3 + 3x = 0
x^2 y + x^3y^3 + 3x = 0
Using the product rule:
2x* y + x^2*dy/dx + 3x^2 y^3 + x^3* (d(y^3)/dx) + 3 = 0
2xy + x^2 dy/dx + 3x^2 y^3 + x^3* 3y^2 dy/dx + 3 = 0
dy/dx(x^2 + 3y^2x^3) =  (-2xy - 3x^2y^3 - 3)
dy/dx=  (-2xy - 3x^2y^3 - 3) / (x^2 + 3y^2x^3)
At the point (-1, 3).
the derivative =  (6 - 81 - 3)/(1 -27)
= -78/-26
=  3.
 
        
                    
             
        
        
        
The product of the expression given above most likely yield a complex number since the expression as well is a complex number. A complex number is a real number, an imaginary number or a number with both real and imaginary number. Its standard form is:
a + bi
<span>( 9 + 5i)( 9 + 8i)
</span>81 + 72i + 45i -40
41 + 117i
