Answer:

Percentage discount offered is 9.47%

Step-by-step explanation:

We are given that,

Retail price of the item = $475

Discount on the item = $45

It is required to find the percentage of discount offered on the item.

So, we have that,

Percentage of discount offered = \frac{Discount}{Retail}\times 100

i.e. Percentage of discount offered = \frac{45}{475}\times 100

i.e. Percentage of discount offered = 0.0947\times 100

i.e. Percentage of discount offered = 9.47%

Hence, the percentage discount offered is 9.47%.

What is the average rate of change from x = 0 to x = −2?
Sergio039 [100]
<h3>Answer is    -3</h3>

How I got that answer:

The graph shows the two points (0,-4) and (-2,2) are on the parabola. The x coordinates of both points are from x = 0 and x = -2 as given in the instructions. Compute the slope of the line through those points. The slope of this line is the exact same as the average rate of change from x = -2 to x = 0.

m = (y2 - y1)/(x2 - x1)

m = (2 - (-4))/(-2-0)

m = (2 + 4)/(-2-0)

m = 6/(-2)

m = -3

A negative slope means the line slopes downhill as you move from left to right. This is a negative average rate of change.

A printing firm charged $35 for printing 600 sheets and $47 for printing 800 sheets find the formula assuming the relationship i
saveliy_v [14]
Here, Coordinates are: (35, 600) & (47, 800)
Now, Slope (m) = y2 - y1  /  x2 - x1
m = 800 - 600 / 47 - 35
m = 200 / 12 = 100 / 6
m = 50/3

Take any one coordinate into slope-intercept formula:
y - y1 = m(x - x1)
y - 600 = 50/3 (x - 35)
y - 600 = 50x/3 - 1750/3
y = 50x/3 + 50/3

In short, Your Answer would be: y = 50x/3 + 50/3

Hope this helps!

In Ms. Smith's class, the ratio of students that walk to school to students that take the subway is 1:2. The ratio of students t
algol13
Let y and z be the no. of students that walk to school, that takes the subway and that takes the bus

We have,
3/y = 1/2
=> y = 6 --- (1)

and,
y/z = 1/3
=> y/z = 1/3 [from (1)]
=> z = 18
Hence the no. of students that takes the bus are 18 students

What is the image of A(8,2) under R90 ?<br> A. (-2,8)<br> B. (2,8)<br> C.( 8,-2)<br> D.(-8,2)
swat32

Answer: A. (-2,8)

Step-by-step explanation:

We know that the rule for rotation of R_{90} is given by :-

(x,y)\rightarrow(-y,x), where (x,y) is the point of pre-image and (-y,x) is a point of image.

The given point of pre-image : A(8,2)

Then after rotation of  R_{90}, we have the image point as :-

(8,2)\rightarrow(-2,8)

Hence, the image point of A(8,2) is (-2,8) .
