4 0

Answer:

B

Step-by-step explanation:

Let the nickels = x

Let the dimes = y

You don't know the total value of either. Nor do you know the total number of either.

You only know the total value of both together.

7.80 added to anything makes it bigger than 7.80 A is wrong.

y cannot be alone it should be multiplied by 0.5    C is wrong

D is wrong for the same reason A is

B is the correct answer. That is the way you write the problem

Number of Coins and value on one side. Total on the other.

A sequence of transformations maps ∆ABC to ∆A′B′C′. The sequence of transformations that maps ∆ABC to ∆A′B′C′ is a reflection ac
quester [9]
The correct answer is " (1) Reflect ABC across the x-axis and call this new triangle A'B'C'. (2) <span>Translate A'B'C' 2 units right and 6 units up so that its image is A''B''C''. "
</span>
It is assumed that the points are
A in ABC is (1,9), B in ABC is (3,12), and C in ABC is (4,4). 

<span>A'' in A''B''C'' is (3,-3), B'' in A''B''C'' is (5,-6), and C'' in A''B''C'' is (6,2).</span>

Both triangles are congruent. Since they are congruent, there are no contractions nor dilations occured. After rotating clockwise, we get A"C"B". So we need to reflect it to get A"B"C"

The “Limited Plan” offers a 15% discount for power usage between 7pm – 9am if most of your usage happens during that time. If no
Dovator [93]

The <em><u>correct answer</u></em> is:

$54.75.

Explanation:

We only receive the discount if the majority of our usage occurs between 7 pm to 9 am.  However, in the month of March we used 450 KWH between these hours and 465 KWH between 9 am to 7 pm; this means we lose our discount.

The rate per KWH is $0.05432; this means we pay

450(0.05432) = 24.444 for the hours of 7 pm to 9 am.

We also pay $0.05432/kwh for the hours of 9 am to 7 pm, but we have an additional 20% premium for the usage between these hours; this means we pay

465(0.05432)(1.2) = 30.31056, for a total of

24.444+30.31056 = 54.75456 ≈ 54.75

given the function f(x) = g(x-3)-2, describe transformation of f(x) on a coordinate plane relative to g(x).
Taya2010 [7]

Answer:

f(x) is obtained by translate g(x) 3 units to the right and 2 units down

Step-by-step explanation:

* Lets talk about the transformation of a function

- If the function f(x) translated horizontally to the right  

by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

by k units, then the new function g(x) = f(x) – k

* Lets study the problem and solve it

∵ f(x) = g(x - 3) - 2

- x-coordinate change from x to x - 3, that means

# x-coordinate is translated 3 units to the right

- y-coordinate change from y to y - 2, that means

# y-coordinate is translated 2 units down

∴ The transformation is:

  translated 3 units to the right and 2 units down

* f(x) is obtained by translate g(x) 3 units to the right and 2 units down
