Hello,

1)
y=(2x-7)(x+5)^3

y'=2(x+5)^3+(2x-7)*3*(x+5)²
if x=4 then
y'=2*9^3+1*3*9²=1701

2)
y=(3x-2)/√(x+2)

y'=(3*√x+2 - (3x-2)/(2*√x+2))/(x+2)

HURRY PLZ!

Answer:

Step-by-step explanation:

$f^{-1}(x)$ means the inverse. The inverse is the function reflected over the y=x line. This means the values have been reversed. (x,y)-->(y,x). We are looking for a point that has reversed values from the table.

The table has (1.-5) so the inverse is (-5,1) or D.

Please help!!! I really don’t get this only I get where the 3 are but please help me for the 4/5 and -0.4!

Naily [24]

Answer:

-0.4 should be in between 0 and -0.5, however be as close to -0.5 as possible while not being ON -0.5.

3 4/5 should be in between 3 and 4, so you can split 4/5 into 8/10 which are equal to each other. Then you can pretend to split the 3 and 4 gap into 10 equal pieces. After you split the gap, count 8 parts to the left of 3.

Step-by-step explanation:

I hope you understand what I mean.

What is the value of x in the equation 4z +16 12 = х - 4?

Serhud [2]

<h3>Solution:</h3>

$\frac{4x + 16}{12} = x - 4 \\ = > 4x + 16 = 12(x - 4) \\ = > 4x + 16 = 12x - 48 \\ = > 16 + 48 = 12x - 4x \\ = > 64 = 8x \\ = > x = \frac{64}{8} \\ = > x = 8$

<h3>Answer:</h3>

x = 8

ExtremeBDS [4]

Answer:

6 packet.

Step-by-step explanation:

Given:

Mrs. White's students are making school spirit packs.

They have 24 bumper stickers and 18 window clings.

Every pack must have the same contents and there should be no leftover items.

Question asked:

What is the greatest number of packs they can make?

Solution:

To find the greatest number of packs could be made by 24 bumper stickers and 18 window clings by using same contents in each pack with no left over items, we will simply use Highest Common Factor.

Factor of 24 - 2, 3, 4, 6, 8, 12, 24

Factor of 18 - 2, 3, 6, 9, 18

Highest Common Factor is 6.

Thus, they can make 6 packet at most.
