HELP 5 STAR + THANKS What series of transformations from △ABC to △DEF shows that △ABC≅△DEF ? a reflection across the y-axis

nirvana33 [79]

In the given triangle, the verteces are A(-4, 1), B(-6, 5), C(-1, 2).
A refrection across the x-axis will result in A'(-4, -1), B'(-6, -5), C'(-1, -2)
A translation of 1 unit to the right will result in A"(-3, -1), B"(-5, -5), C"(0, -2)
A translation of 1 unit down will result in A"'(-3, -2), B"'(-5, -6), C"'(0, -3) which corresponds to points DEF.
Therefore, the series of transformation required to transform ABC to DEF are <span>a reflection across the x-axis followed by a translation of 1 unit right and 1 unit down.</span>

Minny has two coupons, but can use one of them. The first one is for $5 off an item; the second coupon is for 20% off an item. T

joja [24]

Let's first solve for the $5 off coupon,

$28 - 5 = 23$

The final total is $23.00 with $5 off.

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Now for the final price of the 20% off coupon,

$20\% = 0.2$

0.2 or 0.20 is decimal form of 20%. Easier to multiply than in percent form!

$0.2 \times 28 = 5.6$

$5.6 or $5.60 is 20% of 28, we're not done yet!

Lastly, subtract 20% off of 28 (5.6) from 28,

$28 - 5.6 = 22.4$
$22.4 or $22.40 is the final after 20% off!

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Q. Which is less after the discounts??

$23.00 or $22.40

A. $22.40 of course which was the 20% off.

Part A : Which coupon should she use ?

Answer : Well, to get a lower price, less to pay, the 20% off coupon is better!

Part B: How much money will she save by using the better coupon?

Answer : $5.6 / $5.60 is the amount she'll save!

I hope that helps you out!!
