Answer:

$1628

Step-by-step explanation:

A laptop computer was marked up 100% from an original cost of $740.

Marked up price = 100% of $740

= $740

Current price of the Laptop = Initial price of the Laptop + Marked up price

= $740 + $740

= $1480

Last Friday, Judy bought the laptop computer and paid an additional 10% in sales tax. What was her total cost?

Sales tax = 10% of the cost of laptop

= 10% × $1480

Sales tax = $148

Judy's total cost = Price of the Laptop + Sales tax

= $1480 + $148

= $1628

\displaystyle \large{ {a}^{ - n}  =  \frac{1}{ {a}^{n} } }

Compare the terms.

\displaystyle \large{ {a}^{ - n}  =   {( - 2)}^{ - 3} }

Therefore, a = -2 and n = 3. From the law of exponent above, we receive:

\displaystyle \large{ {( - 2)}^{ - 3}  =  \frac{1}{ {( - 2)}^{ 3} } }

<u>E</u><u>x</u><u>p</u><u>o</u><u>n</u><u>e</u><u>n</u><u>t</u><u> </u><u>D</u><u>e</u><u>f</u><u>.</u> (For cubic)

\displaystyle \large{ {a}^{3}  = a \times a \times a }

Factor (-2)^3 out.

\displaystyle \large{ {( - 2)}^{ - 3}  =  \frac{1}{( - 2) \times ( - 2) \times ( - 2)}}

(-2) • (-2) = 4 | Negative × Negative = Positive.

\displaystyle \large{ {( - 2)}^{ - 3}  =  \frac{1}{4 \times ( - 2)}}

4 • (-2) = -8 | Negative Multiply Positive = Negative.

\displaystyle \large{ {( - 2)}^{ - 3}  =  \frac{1}{  - 8}}

If either denominator or numerator is in negative, it is the best to write in the middle or between numerator and denominators.

Hence,

\displaystyle \large \boxed{ {( - 2)}^{ - 3}  =  -  \frac{1}{  8}}

The answer is - 1 / 8

How many solutions are there to the following system of equations?
sweet [91]
4x-8y=0 \\&#10;\underline{-3x+8y=-7} \\&#10;4x-3x=0-7 \\&#10;x=-7 \\ \\&#10;4x-8y=0 \\&#10;4 \times (-7)-8y=0 \\&#10;-28-8y=0 \\&#10;-8y=28 \\&#10;y=\frac{28}{-8} \\&#10;y=-\frac{7}{2} \\ \\&#10; \left \{ {{x=-7} \atop {y=-\frac{7}{2}}} \right.

There is one solution to this system of equations. The answer is B.

Consider the angle. Which TWO statements are true?
svetoff [14.1K]

Answer:

C, E

Step-by-step explanation:

A. INCORRECT

A is wrong because a reflection across the x-axis DOES move the position of the figure (as it is flipped, so the position changes), but it DOES NOT change the angle (since a shift in position doesn't equal to a change in angle measure)

B. INCORRECT

Although a reflection across the x-axis does change the position of the angle, it DOES NOT change the measure of the angle.

C. CORRECT

A reflection across the x-axis does in fact move the position of the figure and does not change the angle measure. Reflections only deal with flipping a figure, not changing it's shape/distorting it so that the angle will change.

D. INCORRECT

A translation right will change the position of the figure but will not change the measure of the angle.

E. CORRECT

Yes, a translation right WILL change the position of the figure but will NOT change the measure of the angle. This is because a translation is simply moving a figure up and down; it has nothing to do with changing the shape of the figure/distorting it so that the angle is different.
