Answer: A.) It is a linear function because there is a constant rate of change in both the input and output values.
============================================================
Explanation:
Note how x is decreasing by 3 each time
- -2-3 = -5
- -5-3 = -8
- -8-3 = -11
At the same time, y is also decreasing by 3 each time
This means we have a linear function. We have,
slope = (change in y)/(change in x)
slope = (-3)/(-3)
slope = 1
Recall that slope is another term for rate of change, so a constant slope means we have a constant rate of change.
----------------
Another way to find the slope is to pick any two points from the table and use the slope formula
m = (y2 - y1)/(x2 - x1)
You should find that any two points you pick will lead to a slope of 1. I recommend you try out all possible pairs to help convince yourself the slope is 1.

Answer:
For each player:
Headbands = 11.67 inches of fabric
Wristbands = 9.31 inches of fabric
Step-by-step explanation:
Shauna is making accessories for the soccer team
For Headbands
She uses 513.48 inches of fabric on headbands for 40 player and 4 coaches
The total number of persons = 40 players + 4 coaches
= 44 persons
Hence:
44 persons = 513.48 inches
1 person = x
Cross Multiply
44x = 513.48 inches × 1
x = 513.48 inches/44
x = 11.67 inches per person
For Wristbands
She uses 372.40 inches of fabric on wristbands for just the players how much fabric was used on a headband and wristband for each player?
Number of players = 40
Hence
40 players = 372.40 inches
1 players = x inches
Cross Multiply
40x = 372.40 inches
x = 372.40 inches/40
x = 9.31 inches
Hence, 9.31 inches per player.
Therefore
For each player:
Headbands = 11.67 inches of fabric
Wristbands = 9.31 inches of fabric
Answer:
Step-by-step explanation:
salut :
en utilisant le theorem de Pythagore on obtient :
AC²= AB² + BC²
(a+5)² = 7²+a²
a²+10a+25 = 49+a²
10a+25 =49
10a =24
donc : a = 24/10 = 12/5 = 2.4 unit
