Answer:

It's the first choice -4 a^12b^8 / 5.

Step-by-step explanation:

\dfrac{-8a^8b^{-2}}{10a^{-4} b^{-10}}

= \dfrac{-8}{10} a^8b^{-2} a^{4} b^{10}

= -\dfrac{4}{5} a^{12}b^{8}

Answer: first choice

Find the coordinates of the points of intersection of the graph of y=13−x with the axes and compute the area of the right triang
Paladinen [302]

The x- and y-intercepts are both 13, so the area is ...

... A = (1/2)bh = (1/2)·13·13 = 169/2 = 84.5 . . . square units

_____

Solve for x when y=0 to find the x-intercept:

... 0 = 13 - x

... x = 13 . . . . . add x

Solve for y when x=0 to find the y-intercept:

... y = 13 - 0

... y = 13 . . . . . additive identity property of 0

If the cost of a dress is $75.00 and Janelle gets it on sale for $60.00, what is
Andrew [12]

Answer:

80%

Step-by-step explanation:

Original price =$75.00

Sale price =$60.00

The percentage discount can be calculated by dividing the sale price by the original price multiplied by 100%.

So % discount = $60.00/$75.00 x 100%

0.8 x 100%

80%

Janelle got the dress on a discount of 80%.

This is so because she got the dress for a price less than the original price
