Answer:

20%

Step-by-step explanation:

Percent decrease = [(original value - new value)/original value * 100]

Percent decrease = [(75 - 60)/75 * 100]

Percent decrease = [15/75 * 100] = 0.2*100= 20

(2a+b) (a-b) + (2a-b) (a+b)
yanalaym [24]

Answer: 4a^2-2b^2 (I think this is right)

Step-by-step explanation:

Using the order of operations I started by multiplying both of the sides separately. The left side of the equation becomes 2a^2-b^2-ab while the right becomes 2a^2-b^2+ab. Then I put the sides together to add them and after combining like terms it becomes 4a^2-2b^2.

Find the equation of the tangent line to the curve 4x3+2y2−11=4xy−x at the point (−1,2).
katrin [286]
Hello : let : y = f(x)     so : y' = f'(x)
calculate : f'(x)  and : f'(-1)  given f(-1) = 2

by derivate : <span>4x3+2y2−11=4xy−x
12x² +4yy' = 4y +4xy' - 1
4yy' - 4xy' = - 12x² +4y -1 
y' ( 4y - 4x) = 4y -12x² -1 ...(*)
if x = -1   y = 2 subsct in : (*)
y' (4(2)-4(-1)) = 4(2)-12(-1)² - 1
2y' = - 9 
y' = - 9/2 = f'(- 1)  ( the slope of the tangent )
</span>of the tangent line to the curve <span>at the point (−1,2) is : 
y - 2 = (-9/2)(x +1)</span>
