The second one because there is all the inputs are different. There is one input for every output.
Answer:
f(n) = 8.5n
Step-by-step explanation:
$8.50 * n = Gross
slope = (y2-y1)/(x2-x1)
= (70-52)/(8-1)
= 18/7
=2.6
point slope form
y-y1 = m(x-x1)
y-52 = 2.6(x-1)
distribute
y-52 = 2.6x-2.6
add 52 to each side
y = 2.6x+49.4
y = 2.6x +49
the initial temperature is 49.4 or about 49
and it increases about 2.6 degrees each week
Answer:
Option D
Y=2.6x
Step-by-step explanation:
When y=10.4 and x=4, these two can be related by the equation
10.4=4x
Making x the subject of the formula then x=10.4/4=2.6
Relating x and y then we have the equation
Y=2.6x
For example, when x is 4 then y=2.6x=2.6(4)=10.4 as given in the question. Therefore, the right option is D
Y=2.6x
