Hi,

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

x−3x=2(4+x)

Step 1: Simplify both sides of the equation.

x−3x=2(4+x)

x+−3x=(2)(4)+(2)(x)(Distribute)

x+−3x=8+2x

(x+−3x)=2x+8(Combine Like Terms)

−2x=2x+8

Step 2: Subtract 2x from both sides.

−2x−2x=2x+8−2x

−4x=8

Step 3: Divide both sides by -4.

−4x/−4 = 8/−4

x=−2

Answer:

x=−2

Have a great day!

Square root of 2 divided by the cube root of 2

kifflom [539]

Answer: $\sqrt[6]{2}$

Step-by-step explanation:

You know that the expression is $\frac{\sqrt{2}}{\sqrt[3]{2}}$

By definition we know that:

$\sqrt[n]{a}=a^{\frac{1}{n}$

You also need to remember the Quotient of powers property:

$\frac{a^n}{a^m}=a^{(n-m)}$

Therefore, you can rewrite the expression:

$=\frac{2^{\frac{1}{2}}}{2^{\frac{1}{3}}}$

Finally, you have to simplify the expression. Therefore, you get:

$=2^{(\frac{1}{2}-\frac{1}{3})}\\=2^{\frac{1}{6}}\\=\sqrt[6]{2}$

Answer:

If the input is n then the output f(n) will be 4n - 8.

Step-by-step explanation:

Let the input of the function is denoted by x and the output is denoted by y.

Then, two ordered pairs of the linear function i.e.(x,y) are (2,0) and (3,4).

Therefore, the relation between x and y i.e. the equation of the straight line will be given by

$\frac{y - 4}{4 - 0} = \frac{x - 3}{3 - 2}$

⇒ y - 4 = 4(x - 3)

⇒ y = 4x - 8

⇒ f(x) = 4x - 8

Therefore, if the input is n then the output f(n) will be 4n - 8. (Answer)

It’s B okay so first you’ll take 47-20 and that will give you 20 then you’ll divide by 4.50 and then your finally answer will be 6.
