Solve the system of equations using subtraction 4x - 3y = -7 4x + y=13
Scorpion4ik [409]

Answer:

(2 , 5)

Step-by-step explanation:

Step 1: Subtract to eliminate x and solve for y

 4x - 3y = -7

- 4x + y= 13

----------------

-4y = -20

y = 5

Step 2. Plug in the value of y into one of the equations and solve for x.

4x - 3y = -7

4x - 3(5) = -7

4x - 15 = -7

4x = 8

x = 2

Sqrt45a^5 simplified
Anestetic [448]

\sqrt{45a^5}

[scomposition of 45]

\sqrt{9*5*a^5}

[9 = 3^2, must use this notation (not 3*3)]

\sqrt{3^2*5*a^5}

[We appy one of the proprieties of square roots]

\sqrt{3^2}* \sqrt{5}*\sqrt{a^5}

[now we semplify: we must take out as much as possible all the elements under roots]

[to do that, we must divide the esponent of each element with the index of square roots (2)]

so

\sqrt{3^2}, 2/2 = 1

\sqrt{5}, 1/2 = 0 with 1 of rest

\sqrt{a^5}, 5/2 = 2 with 1 rest

[well, after do that, we can take out the elements under tbhe square roots!]

The quotient of each division is the esponent of the element out of the root

The rest of each division is the esponent of the element under the root

so:

3^{1} (quotient = 1, see the first operation) * \sqrt{5} (rest = 1, see the second operation) * a^{2} (quotient = 2, see the third operation) * \sqrt{a^1} (rest = 1, see the third operation)

The final result is:

3 (=3^1) * a² * √5 * √a

3a²√5a

It's more intuitive and easy, but the explanation (necessary) is very long. If you have other questions, ask me here in the comments! Also sorry for my english, not so good!

Confused from where I left off PLEASE help
Leviafan [203]

Not sure the right equation so i did both....

#1 - √12m√15m=1m√2

Simplifies to:

13.416408m2=1.414214m

Let's solve your equation step-by-step.

13.416408m2=1.414214m

Step 1: Subtract 1.414214m from both sides.

13.416408m2−1.414214m=1.414214m−1.414214m

13.416408m2−1.414214m=0

Step 2: Factor left side of equation.

m(13.416408m−1.414214)=0

Step 3: Set factors equal to 0.

m=0 or 13.416408m−1.414214=0

m=0 or m=0.105409

Answer:  m=0 or m=0.105409


#2 - √12m√15m

Simplifies to:

13.416408m2

=13.416408*m2

=13.416408*(m*m)

=13.416408m2
