Najat is selling raffle tickets. The table shows the cost (in dollars) of buying different numbers of tickets.
oksano4ka [1.4K]

Answer:

The equation relating x and y is: y=4x

Step-by-step explanation:

Let x represent number of tickets

and y represent cost

a) Plot the ordered pairs

The ordered pairs (1,4),(2,8),(3,12),(4,16) is plotted in figure attached.

b)  Write an equation relating x and y

y= 4x

Now checking by putting values of x to see, if we get values of y

if x=1,  then y=4x => y=4*1 =>y=4

if x=2 then y=4x => y=4*2 =>y=8

if x=3 then y=4x => y=4*3 =>y=12

So, we get same values as table.

The equation relating x and y is: y=4x

First five term for An=n^2-2n
densk [106]

First 5 terms are: -1,0,3,8,15

Step-by-step explanation:

we will put n=1,2,3,4,5 to find first 5 terms of the sequence

Explicit formula for sequence is:

a_n = n^2-2n

Putting n=1

a_1 = (1)^2-2(1)\\= 1-2\\= -1

Putting n=2

a_2 = (2)^2-2(2)\\= 4 - 4 \\=0

Putting n=3

a_3 = (3)^2-2(3)\\= 9-6\\= 3

Putting n=4

a_4 = (4)^2 - 2(4)\\= 16-8 \\= 8

Putting n=5

a_5 = (5)^2-2(5)\\= 25 - 10\\= 15

Hence,

First 5 terms are: -1,0,3,8,15

10 points - questions #13-15. W/ work please.

13. To find the angle of WZY you would have to grab the angle of a straight line (180) and subtract it from the already shown angle of 105. 180 - 105 = 75. 75 is the measure of WZY
14. WZ has a measure of 24 since the parallel side is also 24 (not too sure about this one)
15. XYZ Has the same angle as its corresponding angle of 105. The angle is also 105
