Answer:

$2x + 2(x - 3) = 18 \\ 2x + 2x - 6 = 18 \\ 4x = 24 \\ x = 24 \div 4 = 6 \\ y = x - 3 = 6 - 3 = 3$

Simplify the following expression using properties of exponents.<br> (4z)⁻³×(2z)⁵

Elena-2011 [213]

Answer:

z²/2

Step-by-step explanation:

The applicable properties of exponents are ...

(ab)^c = (a^c)(b^c)

(a^b)(a^c) = a^(b+c)

a^-b = 1/a^b

$(4z)^{-3}\cdot(2z)^5=(4^{-3})(z^{-3})(2^5)(z^5)=\dfrac{32}{64}z^{-3+5}\\\\=\boxed{\dfrac{z^2}{2}}$

What is the equation for the line of reflection? On a coordinate plane, triangle A B C has points (6, 3.7), (5.4, 2), (1, 3). Tr

Klio2033 [76]

Answer:

The equation of the line of reflection will be x = y.

Step-by-step explanation:

On a coordinate plane, triangle Δ ABC has points (6, 3.7), (5.4, 2), (1, 3). And triangle Δ A'B'C' has points (3.7, 6), (2, 5.4), (3, 1).

Now, Δ A'B'C' is the image triangle of Δ ABC and we have to find the equation of the line of reflection.

We know that after reflection of a point P(h,k) over the line x = y the image will be P'(k,h).

Same is happened in case of Δ ABC and Δ A'B'C'.

Therefore, the equation of the line of reflection will be x = y. (Answer)
