Answer:the pairs are not a quadratic eqation
Step-by-step explanation:
The differences between the differences of the y value are not consistent
<h3>
Answer:</h3>
y = -4x +2
<h3>
Step-by-step explanation:</h3>
The slope-intercept form of the equation for a line is conveniently found from the point-slope form. In either case, you need to know the slope. That is ...
... slope = m = (change in y)/(change in x)
For the first two points, the slope is ...
... m = (-6 -(-2))/(2 -1) = -4
Using the point-slope equation for slope m and point (h, k) written as ...
... y = m(x -h) +k
we can substitute m = -4 and (h, k) = (1, -2) to get ...
... y = -4(x -1) -2
... y = -4x +2 . . . . . . . simplify
1) y = 1x + 95.50
x = number of bandanas
2) y = (1 • 50) + 95.50
$145.50 for 50 bandannas
3) 116.50 = 1x + 95.50
get x by itself
116.50 = 1x+ 95.50
-95.50 -95.50
21 = 1x
divide by 1
21 = x
you get 21 bandannas when you pay $116.50
Answer:
D
Explanation:
The number multiplied by the variable is always the increasing factor.
