The answer would be 6 3/8
Hope this helps c:
Step-by-step explanation:
the one on the left (b)
y= mx+b
at x= 0 y = -2
then b= -2
at x= -1 y= 1
1= -m -2
m= -3
y= -3x -2
......
the one on the right side (d)
at x= 2 y = 1
at x= 4 y = 2
1= 2m+b
2= 4m +b
subtract
1= 2m
m= 1/2
y= 1/2 x
Answer:
The increase is 3/4
75%
Step-by-step explanation:
<span>The curve equation y3 + 3yx - x3 = 9</span>
Differentiate implicitly with respect to x.
<span>3y2(dy/dx) + 3[y + x(dy/dx)] - 3x2 = 0</span>
<span>3y2(dy/dx) + 3y + 3x(dy/dx)] = 3x2</span>
<span>(dy/dx)(3y2 + 3x) = 3x2 - 3y</span>
<span>dy/dx = 3(x2- y)/3(y2 + x)</span>
<span>dy/dx = (x2- y)/(y2 + x)</span>
Slope is easy you can look that up and the y- intercept is the point of the y axis
