PLEASE HELP WITH THIS ILL GIVE BRAINLIEST
Mrrafil [7]

Answer:

\text{a. }x=7, x=-7, \\\text{b. }x=16, x=-16,  \\\text{c. }x=3, x=-17, \\\text{d. }x=7, x=-7

Step-by-step explanation:

For |x|=y, we have two cases:

\begin{cases}x=y, \\x=-y\end{cases}

Using this, we can solve all four of the problems:

\text{a. }|x|=7,\\\begin{cases}x=7, \\x=-7\end{cases}

\text{b. }|2x|=32,\\\begin{cases}x=16, \\x=-16\end{cases}

\text{c. }|x+7|=10,\\\begin{cases}x+7=10, x=\boxed{3,} \\x+7=-10, x=\boxed{-17}\end{cases}

\text{d. }5|x|=35,\\\begin{cases}x=7, \\x=-7\end{cases}

You are holding a glass of orange juice with ice cubes floating on it.
hammer [34]
You are holding a heterogeneous mixture but once the ice cubes melt the mixture will become homogeneous. A heterogeneous mixture is when you can see and separate the different parts of the item you have. A homogeneous solution is when you can't separate the item you have by physical means<span />

Simplify the given expression, using only positive exponents. Then complete the statements that follow. [ (x2y3)−1 (x−2y2z)2 ] 2
Firlakuza [10]

Answer: y²z⁴ / x¹²

  • The exponent of x is 12

  • The exponent of y is 2

  • The exponent of z is 4

Explanation:

1) Given expression to simplify:

((x^2y^3)^{-1}(x^{-2}y^2z)^2)^2

2) Property: power of power:

(x^{-4}y^{-6})(x^{-8}y^8z^4)

3) Property: product of powers with the same base

x^{(-2-8)}y^{(-6+8)}z^4

4) Add the exponents

x^{-12}y^2z^4

5) Pass the negative power to the denominator:

\frac{y^2z^4}{x^{12}}

The exponent on x is  12. The exponent on y is 2. The exponent on z is 4.
