-8x - 10y = 24 <br>6x + 5y = 2<br>​
iris [78.8K]

-8x - 10y = 24

6x + 5y = 2

-8x - 10y = 24

12x + 10y = 4

4x = 28

x = 7

6(7) + 5y = 2

42 + 5y = 2

5y = -40

y = -8

Given the algebraic expression the quantity 64 times x to the two-thirds power end quantity to the negative one-third power comm
11111nata11111 [884]

The given algebraic expression is equal to 1 divided by the quantity 4 times x to the two-ninths power end quantity. The correct option is B.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given algebraic expression can be simplified using the exponential properties. Therefore, the simplification of the algebraic expression can be done as shown below.

(64x^{\frac23})^{-\frac13}

= (4^3)^{-\frac13} \times x^{(\frac23 \times -\frac13)}\\\\= 4^{(3 \times -\frac13)} \times x^{(\frac23 \times -\frac13)}\\\\= 4^{-1} \times x^{-\frac29}\\\\=\dfrac{1}{4x^{\frac29}}

Hence, the correct option is B.

AVprozaik [17]

Answer:

A.)lPace the compass needle on M and, keeping the compass width the same, draw two arcs that intersect

Step-by-step explanation:

In the construction of a line perpendicular to AB←→ and passing through an external point M the first step must be"Place the compass needle on M and, keeping the compass width the same, draw two arcs that intersect AB←→". After that you can draw arcs from intersection points (keeping the compass width same as before) to the opposite side of M, name it as N than use straightedge to draw line passes through M and n that would be perpendicular line to AB.
