Solve for x.

5(x−3.8)=22

enter the answer as the value that you found for x. do not round your answer.

X=8.2

Step-by-step explanation:

First you do distributive property

5x-19=22

*(This is how the problem looks now)*

Then you add 19 to both sides

5x=41

Then you divide, getting the answer of 8.2

Hope it helped!

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

i believe that the answer is

b. y-1=-2(x-4)

hope this !
