Answer:
15 seeds
Step-by-step explanation:
Set up a ratio that represents the problem:
Sown Seeds : Seeds That Grow
100 : 75
Find the unit rate:
The unit rate is when one of the numbers in a ratio is 1. For this problem, let's make the number of sown seeds equal to one.
To do this, divide by 100 on both sides of the ratio.
100 : 75
/100 /100
1 : .75
This means that if Tim sows 1 seed, .75 will grow.
Answer the question:
We need to find the number of seeds that would grow if Tim planted 20 seeds. Therefore, multiply by 20 on both sides of the ratio.
1 : .75
x20 x20
20 : 15
Therefore, if Tim plants 20 seeds, we would expect 15 to grow.

<h3>What is a piece-wise function?</h3>
A piece-wise function is a function that has different definitions, depending on the input.
In this problem, for inputs between -2 and 2, the function is a line that goes through (-2,-4) and (2,6). The slope is:
m = (6 - (-4))/(2 - (-2)) = 2.5.
The y-intercept is of b = 1, hence the rule is:
For x greater than 2 and less than 6, the function is constant at -3, hence the rule is:
