Question

Early last summer, Xavier planted a flower. Let y be the flower's height (incentimeters) x days after he planted it. Use the table to relate the independent variable x to thedependent variable y. First describe the relationship in words. Then write an equation. Use theequation to find the flower's height after 3 days.

Answer 1

i) The equation is; y = x + 16

ii) After 3 days, the height of the flower is 19 centimeters

Here, we want to describe a relationship

We start by describing the relationship between the flower's height and the number of days after it was planted

As we can see from the table, the value of x plus 16 equals the value of y

In the equation from, we have this as;

`x+16\text{ = y}`

To find the height of the flower after 3 days, we simply substitute the value of 3 for y

We have this as;

`\begin{gathered} y\text{ = 16 + 3} \\ y\text{ = 19 } \end{gathered}`
