You are offering 16.4% for customers who purchase the 6-coupon book for the oil changes. This problem can be solved by doing a simple percentage formula of mathematic. The customer had to pay $80 only for six oil changes which cost $95.7 ($15.95 * 6) at the original price and the difference between the coupon price and the original price is the discount (($95.7-$80)/$95.7 *100%)<span>. </span>

Graph this function:<br> y = 2x
77julia77 [94]

Graph is attached below.

Step-by-step explanation:

We have to graph function y = 2x,

From  equation, we can see a linear relationship between the values of x and y.  This equation shows that the value of y is double than the value of x.

For example,

<u>x = 0</u>

y = 2(0)

y = 0

So, point would be (0,0)

<u>x = 1</u>

y = 2(1)

y = 2

So, point would be (1,2)

<u>x = 3</u>

y = 2(3)

y = 6

So, point would be (3,6)

<u>x = -1</u>

y = 2(-1)

y = -2

So, point would be (-1,-2)

<u>x = -3</u>

y = 2(-3)

y = -6

So, point would be (-3,-6)

By matching these points, a linear graph can easily be drawn. I have also attached the graph pic below.

BlackZzzverrR [31]

Answer:

the answer is b(-7/4)

Step-by-step explanation:

2(x+5)-3=(2x=1)+1

2x+10-3=-(2x+1)+1

2x+7=-(2x+1)+1

2x+7-2x-1+1

2x+7=2x

2x+7-7+2x-7

x=-7/4

A set of data is given: 3,7,11,11,16. Sue calculated a center of measure and got 9.6. Which center of measure did she calculate.
QveST [7]

Answer: Average or Mean

Step-by-step explanation:

The center of measure calculated was the average or mean. To get the mean of a set of numbers, we have to add all the numbers given and then divide them by the numbers.

In this case, the mean of 3,7,11,11,16 will be:

= (3 + 7 + 11 + 11 + 16) / 5

= 48/5

= 9.6

Interest calculated on a balance every three months is said to be compounded quarterly.
Mariulka [41]

Answer:

True

Step-by-step explanation:

The year is typically divided into equal different lengths of time. There are, for example, quarters, which divide the year by 4, i. e., in 4 periods of 3 months each. Other example are semesters, in this case, the year is divided into 2 periods of 6 months each. Taking this into account, an interest calculated on a balance every three months is compounded quarterly.
