Differentiate with respect to x : 2xe^x​
Gnom [1K]

\\ \sf\longmapsto \dfrac{d}{dx}2xe^x

  • Apply product rule

\\ \sf\longmapsto \dfrac{d}{dx}2x(e^x)

\\ \sf\longmapsto 2x\dfrac{d}{dx}e^x+e^x\dfrac{d}{dx}2x

\\ \sf\longmapsto 2xe^x+2e^x

\\ \sf\longmapsto 2e^x(x+1)

Julain has 200ml of 35% hand sanatizer. Sarah has 150ml of 85% hand sanatizer. They mix the sanatizers together in an effort to
Cerrena [4.2K]

Answer:210ml, 140 ml, 60%

Step-by-step explanation:

Given

Juli has 200 ml of 35% hand sanitizer

Sarah has 150 ml of 85% hand sanitizer

The mixture has 60% con. i.e. 60 % is Alcohol and 40 % water

The final volume of the mixture =200+150=350 ml

Now, 60% of 350 ml= 350\times 0.6=210\ ml

So, pure Alcohol is 210 ml

Water in the final mixture= 350\times 0.4=140\ ml

The concentration of Alcohol is 60%

PLEASE HELP!!!<br> EQUATIONS!!! ASAP :)

1)solve for y.

4x+y=7

Add -4x to both sides.

4x+y+−4x=7+−4x

y=−4x+7



2) solve for y.

y−5x=9

Add 5x to both sides.

−5x+y+5x=9+5x

y=5x+9



3) solve for y.

3y−15x=12

Add 15x to both sides.

−15x+3y+15x=12+15x

3y=15x+12

Divide both sides by 3.

3y/3=15x+12/3

y=5x+4




4) solve for y.

8x+2y=18

Add -8x to both sides.

8x+2y+−8x=18+−8x

2y=−8x+18

Divide both sides by 2.

2y/2=−8x+18/2

y=−4x+9
 



5 ) solve for y.

7x−y=35

Add -7x to both sides.

7x−y+−7x=35+−7x

−y=−7x+35

Divide both sides by -1.

−y/−1=−7x+35/−1

y=7x−35



6)  solve for y.

4x+1=9+4y

Flip the equation.

4y+9=4x+1

Add -9 to both sides.

4y+9+−9=4x+1+−9

4y=4x−8

Divide both sides by 4.

4y/4=4x−8/4

y=x−2



7)  solve for x.

y=5x−2x

Flip the equation.

3x=y

Divide both sides by 3.

3x/3=y/3

x=1/3y



8) solve for x.

r=x+9x

Flip the equation.

10x=r

Divide both sides by 10.

10x/10=r/10

x=1/10r



9) solve for x.

b=3x+9xy

Flip the equation.

9xy+3x=b

Factor out variable x.

x(9y+3)=b

Divide both sides by 9y+3.

x(9y+3)/9y+3=b/9y+3

x=b/9y+3



10)  solve for x.

w=2hx−11x

Flip the equation.

2hx−11x=w

Factor out variable x.

x(2h−11)=w

Divide both sides by 2h-11.

x(2h−11)/2h−11 = w/2h−11

x=w/2h−11
 

11) solve for x.

p=4x+qx−5

Flip the equation.

qx+4x−5=p

Add 5 to both sides.

qx+4x−5+5=p+5

qx+4x=p+5

Factor out variable x.

x(q+4)=p+5

Divide both sides by q+4.

x(q+4)/q+4=p+5/q+4

x=p+5 / q+4




12) solve for x.

m=9+3x−dx

Flip the equation.

−dx+3x+9=m

Add -9 to both sides.

−dx+3x+9+−9=m+−9

−dx+3x=m−9

Factor out variable x.

x(−d+3)=m−9

Divide both sides by -d+3.

x(−d+3)/−d+3=m−9/−d+3

x=m−9/−d+3
