Combine like terms. -2y+y=-y. The equation is now -y-3=6. You need to get the y by itself so add 3 to both sides. The equation is now -y=9. You are solving for y so divide both sides by -1. The equation will be y=-9. The answer is y=-9. Hope this helps! ;)

Each TTF site bought a new rope bridge for 4,500. TTF will make monthly payments of $350 until the bill is paid. Write an equati
strojnjashka [21]

Answer: 4500 - 350m

Step-by-step explanation:

From the question, we are informed that each TTF site bought a new rope bridge for 4,500 and that TTF will make monthly payments of $350 until the bill is paid.

The equation for the unpaid balance B after m monthly payments will be:

= 4500 - 350m

where me = number of months

For example, if the number of months used is 4 months, the unique balance will be:

= 4500 - 350m

= 4500 - 350(4)

= 4500 - 1200

= 3300

Complete the steps to simplify (y^4/3•y^2/3)^-1/2. Apply the product of powers property to the expression inside the parentheses
MrRissso [65]

Option A

\left(y^{\frac{4}{3}} \cdot y^{\frac{2}{3}}\right)^{\frac{-1}{2}} = \left(y^{2}\right)^{\frac{-1}{2}}

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

\left(y^{\frac{4}{3}} \cdot y^{\frac{2}{3}}\right)^{\frac{-1}{2}}

<em><u>Product of powers property:</u></em>

The product of powers property tells us that when you multiply powers with the same base you just have to add the exponents

Which is represented as,

a^m.a^n = a^{m+n}

<em><u>Therefore, the given expression becomes,</u></em>

\left(y^{\frac{4}{3}+\frac{2}{3}}\right)^{\frac{-1}{2}}

Now add the exponents, we get

\left(y^{\frac{4+2}{3}}\right)^{\frac{-1}{2}}

Simplify the above expression

\left(y^{\frac{6}{3}}\right)^{\frac{-1}{2}}

Simplify the exponent of y, we get

\left(y^{2}\right)^{\frac{-1}{2}}

Thus Option A is correct
