The answer is 20 since 1/5 of 20 is 4, and 20 + 4 = 24.
        
                    
             
        
        
        
Answer:
-9
Step-by-step explanation:
What b represents here is the y intercept.
The first thing we will do here is to find the slope.
Mathematically;
m = (y2-y1)/(x2-x1)
Plugging the values;
m = (12-3)/(7-4) = 9/3 = 3
The equation can thus be written as;
y = 3x + b
To get b, we can use any of the points since they lie on the line
Let’s use point M
Substitute the values of x and y in the equation 
3 = 3(4) + b
3 = 12 + b
b = 3-12 = -9
 
        
                    
             
        
        
        
The x-intercept is 8 because it passes through the horizontal line (x) at point 8.
The y-intercept is -4 because it passes through the vertical line a (y) at point -4.
The correct answer is B.
Hope this helps!
        
             
        
        
        
The answer is y=-8 I’m pretty sure
        
             
        
        
        
f(x) = 5x²
f(10) = 5(10)²  = 5(100)  = 500
f'(x) = 10x
f'(10) = 10(10)   = 100  
Now, find the line that passes through (10, 500) and has a slope of 100
y - y₁ = m(x - x₁)
y - 500 = 100(x - 10)
y - 500 = 100x - 1000
          y = 100x - 500
