Answer:
y=12x 12=k k=constant of Proportionality
Step-by-step explanation:
Answer:
Step-by-step explanation:
-x/4 <7
Multipy both sides by 4
4 (- x /4 ) < 7 . 4
Simplify
- x < 28
Multiply both sides by - 1 ( inverse the inequality)
( -x ) ( -1 ) > 28 ( -1 )
Simplify
x > - 28 Answer D
Answer:
1.) y = 1.10(x – 1) + 1.35
Step-by-step explanation:
When x pounds of apples are purchased, the number of "additional" pounds is (x-1). The cost of those additional pounds is then added to the cost of the first pound to get ...
y = 1.10(x -1) +1.35
_____
<em>Comment on the function rule</em>
Personally, I think it is easier to write the rule as y = 1.10x +0.25, considering the first pound to have a $0.25 premium added to its otherwise $1.10 cost. This saves an operation when evaluating the formula for some value of x.
the line of best fit would be something like in the picture(but straighter)
you would get the equation of it by using y = mx+c
m = the change of y divided by the change of x on the line
c = when the line was on the y axis
put the values in y = mx + c and you have the equation
once you have that just replace x with 100 and rearrange it to equal y and you have the customers
1000 millimeters = 100 centimeters
