Answer:

f(x) = 9x + 4

Step-by-step explanation:

Consider the output values

13, 22, 31, 40, 49

The difference between consecutive terms is constant, that is

22 - 13 = 31 - 22 = 40 - 31 = 49 - 40 = 9

This indicates the function is of the form

y = 9x + c ( where c is a constant )

To find c substitute the values of the input

x = 1 : y = 9(1) + c = 13 → 9 + c = 13 ⇒ c = 4

x = 2 : y = 9(2) + c → 18 + c = 22 ⇒ c = 4

x = 3 : 9(3) + c = 31 → 27 + c = 31 ⇒ c = 4

x = 4 : 9(4) + c = 40 → 36+ c = 40⇒ c = 4

x = 5 : 9(5) + c = 49 → 45 + c = 49 ⇒ c = 4

The value of the constant is 4

Thus the function representing the data is f(x) = 9x + 4

Answer:

A. f(x)=9x+4

Step-by-step explanation:

Function is f(x) =9x+4, because if x=1, then f(1)=9*1+4=9+4=13;

if x=5,then f(5)=9*5+4=45+4=49

Problem 2

Plot point L anywhere that isn't on segment JK. Draw a line through point L. I find it helps to make the lines parallel.

Next, use a compass to measure the width of segment JK. Keeping this same width, transfer the nonpencil end of the compass to point L. Draw an arc that crosses the line through L.

Mark this intersection point M. Lastly, use a pen or marker to form segment LM and erase everything else of that line.

======================================================

Problem 3

The ideas of the previous problem will be used here. We copied segment JK to form congruent segment LM. So JK = LM.

The same steps will be used to form segment GN where GN = EF. In other words, segment GN is a perfect copy of segment EF.

If you repeat these steps again, you'll get another segment of the same length. This segment goes from point N to point H. So NH = GN = EF

Then we can say,

GH = GN + NH

GH = EF + EF

GH = 2*EF

After a 40% discount an item costs $360. what is the original cost
Reptile [31]
Original Price = Final Price / (100 - Discount)

So...

OP = 360 / 100 - 0.40
OP = 360 / 0.60
OP = 600

The original price is $600. 

To check, do 600 - (600 * 0.40) in a calculator. You get 600 - 240 = 360, the discounted cost.

Some farms use a hay elevator to move bales of hay to the second story of a barn loft. The bottom of the elevator is 9 meters fr
-Dominant- [34]

Answer: The height is 6.07 meters

Step-by-step Explanation: The distance between the elevator and the bottom of the barn is given as 9 meters. Also for the hay elevator to move bales of hay to the second story of the barn lift it makes an angle of elevation of 34 degrees with the ground. With these we can derive a right angled triangle with the reference angle as 34 degrees, the side facing it which is the height or h (opposite) is yet unknown, and the side between the reference angle and the right angle (adjacent) is 9. We shall apply the trigonometric ratio as follows;

Tan 34 = opposite/adjacent

Tan 34 = h/9

0.6745 = h/9

0.6745 x 9 = h

6.0705 = h

Therefore the approximate height of the barn to the ground is 6.07 meters

Your key word is divide. You'll want to divide your 6 pizzas by your four friends, than most likely convert it to a fraction (unless your teacher accepts decimals.), message if you need more help.
