Answer:
Domain: {-2, -3, 6, 8, 10}
Range: {-5, 1, 7, 9}
Step-by-step explanation:
Given:
{(6, -5), (-2, 9), (-3, 1), (10, 7), (8, 9)}
✔️Domain:
This includes all the set of the x-values that are in the relation. This includes, 6, -2, -3, 10, and 8.
Thus, the domain can be represented as:
{-2, -3, 6, 8, 10}
✔️Range:
This includes all corresponding y-values in the relation. They are, -5, 1, 7, and 9.
Range can be represented as:
{-5, 1, 7, 9}
R=( 432/12)* 1/2= 36* 1/2= 18
R= 18
2/6 and it = 3/6 which simplified as 1/2
Try 75. I could be wrong but try it
Answer:
The average height of a 5-year-old boy is ![98.9\ cm](https://tex.z-dn.net/?f=98.9%5C%20cm)
Step-by-step explanation:
Let
x------> the ages of boys between 2 and 10 years old
y-----> the average heights in centimeters
we have
![y=6.3x+67.4](https://tex.z-dn.net/?f=y%3D6.3x%2B67.4)
so
For
year-old-boy
substitute in the equation the value of x to find the value of y
![y=6.3(5)+67.4=98.9\ cm](https://tex.z-dn.net/?f=y%3D6.3%285%29%2B67.4%3D98.9%5C%20cm)
