<u>Step-by-step explanation:</u>
A linear function : Linear functions are those whose graph is a straight line.
, A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. a is the constant term or the y intercept. It is the value of the dependent variable when
. b is the coefficient of the independent variable.
- rate of change: Ratio between two related quantities that are changing.
- slope: The ratio of the vertical and horizontal distances between two points on a line; zero if the line is horizontal, undefined if it is vertical.
In real life, we know that voltage is directly proportional to current , having resistance as a proportionality constant or more precisely slope of line :
, slope remains constant but , voltage is directly proportional to current .
I think you forgot to add the cord picture?
Answer:
a^2 + -2
Step-by-step explanation:
This is using the Foil method : First , Outer , Inner , Last using this should help you solve to get your answer .
Hope this helped :)
For red is it is 9/41 and or blue it is 10/41 so together 19/41 so the answer is b: 19/41
