Answer:

  see below

Step-by-step explanation:

A relation is a <em>function</em> when there is exactly one output for each input. That is the case in this table, so the relation between the original price and sale price is a function.

John is arguing that they should use the following expressions to calculate the final cost of this item: (20-20•0.15)+(20-20•0.1
Vikki [24]
If they use (20-20x0.15)+(20-20x.015)x0.05 the final cost would be $34.05

Hope this helps

Please help with this algebra question
blagie [28]
Do you know how to graph the equation 2x-1?

If you do then graph it.

After, check the inequality - it is Y is less than the equation so you will be filling in everything below the line you graphed

IF you don't know how to graph:
You will have a line that goes up 2 then right 1

The equation is really 2/1 x as in 2 right 1 right

The line will start from y=-1 or 1 right below 0,0 because of the -1 at the end of the equation and the line will travel in both direction for infinity (Or as big as the graph is)

So start at y=-1 then go up 2, right 1 and place a point. Keep doing that (down 2 left 1 when going in the opposite direction) Finally just make a line through all those points you made

Use the equation below to answer the question.
JulijaS [17]

Answer:

The signa notation to represent the first five ten f(x) is given by f(x)=\sum\limits^{5}_{n=1}a_n

Step-by-step explanation:

Given sequence is -5, -9, 13...

Let f(x) be the given sequence and is denoted by

f(x)=\{-5,-9,-13,...\}

Let the first term be a_1, 2^{\textrm{nd}}  term be a_3,...

ie, a_1=-5,a_2=-9, a_3=-13,...

To find the common difference d:

d=a_2-a_1

=-9-(-5)

=-9-(+5)

d=-4

d=a_3-a_2

=-13-(-9)

=-13+9

d=-4

Therefore the common difference d is -4 for given sequence f(x) with a_1=-5 and d=-4, the seqence f(x) is an arithmetic sequence

By defintion of arithmetic sequence

a_n=a+(n-1)d\hfill(1)

Now to find a_4, a_5:

put n=4 in equation (1)

a_4=a+(4-1)d

a_4=-5+(3)(-4)        [since a=-5, d=-4]

=-5-12

a_4=-17

in equation (1)

a_5=a+(5-1)d

a_5=-5+(4)(-4)       [since a=-5, d=-4]

=-5-16

a_5=-21

Therefore a_4=-17 and a_5=-21

Therefore f(x)=\{-5,-9,-13,-17,-21,...\}

Now to represent the sum of the first five terms of f(x) using sigma notation as below

f(x)=\sum_{n=1}^5 a_n

where \sum_{n=1}^5 a_n=a_1+a_2+a_3+a_4+a_5

           -5-9-13-17-21

\sum_{n=1}^5 a_n=-65
