Evaluate the function for h(1)

h(x) = |1 – 7x|

We conclude that:

Step-by-step explanation:

Given

The function is

To determine

h(1) = ?

Given the function

substitute x = 1 in the function

Apply absolute rule:   |-a| = a

Therefore, we conclude that:

a

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
