What is the solution of

Mathematics
2 answers:
loris [4]3 years ago

Answer:

x = -1/2

Step-by-step explanation:

1-3x = x+3

Add 3x to each side

1-3x+3x = x+3x+3

1 = 4x+3

Subtract 3 from each side

1-3 = 4x+3-3

-2 = 4x

Divide each side by 4

-2/4 = 4x/4

-1/2 =x

Answer:

x= -1/2

Step-by-step explanation:

To solve, we want the variables on one side of the equation, and the numbers  on the other

1-3x=x+3

Add 3x on both sides

1=4x+3

Subtract 3 from both sides

-2=4x

Divide by 4 on both sides

x= -1/2

Hope this helps! :)

Determine whether the improper integral converges or diverges, and find the value of each that converges.
Brrunno [24]

Answer:

Converges at -1

Step-by-step explanation:

The integral converges if the limit exists, if the limit does not exist or if the limit is infinity it diverges.

We will make use of integral by parts to determine:

let:

u=x             dv=e^(2x)\cdot{dx}

du=dx         v=2\cdot{e^(2x)}

\int\limits^a_b {u} \, dv = uv -\int\limits^a_b {v} \, du

\int\limits^a_b {x\cdot{e^2^x} \, dx =2xe^2^x- \int\limits^a_b {2e^2^x} \, dx

\int\limits^a_b {xe^2^x} \, dx = 2xe^2^x-2e^2^x-C

We can therefore determine that if x tends to 0 the limit is -1

\lim_{x \to \0} 2xe^2^x-2e^2^x=0-1=-1

What is the answer i'm having trouble :( click the picture
Vikentia [17]

Step-by-step explanation:

So 2 pints = 1 quart

The she need 6 pints which is

2 cups = 1 pint

She need 6, so mutiply with 6
