What is a example of a linear function?

4x + y = 0

Step-by-step explanation: To determine whether the function 4x + y = 0 is linear, quadratic, or neither, let's first set the function equal to y by subtracting 4x from both sides to get y = -4x or y = -4x + 0.

Now, we can see y = -4x + 0 is in the form y = mx + b.

When a function is written in the form y = mx + b, we know that it's a linear function.

Another way to tell that it's a linear function is that the x in the function is raised to the first power.

answer: 1inch=7days  

12inch=12*7=84days

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
