Hey! The answer is 25,4 centimeters.
Step-by-step explanation:
In a linear function you can use y=mx+n
So if x = hours and y= height.
You know that
So:
If you multiply (24,8=26m +n) x-1
It is: -24,8 = -26m -n
Adding up the other equation
-24,8 = -26m -n
<u>27,8 = 11m + n</u>
<u>3 = -15m</u>
<u>m= -0,2</u>
So
27,8 = 11 x 0,2 + n
27,8 = -2,2 + n
30 = n
This results that te linear function for this equation is:
y = -0,2x + 30
The answer is
y=23(-0,2) + 30
y=-4,6+30
y=25,4
