Answer:
do it yoself
Step-by-step explanation:
xdddddd
X (Time in Hours) y (Distance)
0 900
1 850
2 800
3 750
The y-intercept of this function would be the value of y when x = 0
Reading from the table, when x = 0, y = 900
Interpreting this value it means that initially, the distance of the car from its destination is 900 miles
------------------------------------------------------------------------------------------------------------
PART B
The rate of change is calculated by finding the vertical and horizontal distance between two points
The decrease is the same value every time; for every hour, there's a decrease of 50 miles.
So, the rate of change is 50 miles per hour
------------------------------------------------------------------------------------------------------------
PART C
The function is in the straight line equation form: y = -50x + 900
The value -50 represents the negative slope (the decrease in distance)
The value 900 represents the y-intercept
The car reaches its destination when y = 0, so the value of x would be
0 = -50x + 900
50x = 900
x = 900/50
x = 18 hours
The domain of the function is 0 ≤ x ≤ 18
Here, I'll use C for combinations.
There are 15 boys and you need 3 so 15 C 3 ways
There are 30 girls and you need 7 so 30 C 7
and there are 45 total and you need 10 so 45 C 10
The answer is [15 C 3 • 30 C 7] over 45 C 10
so do that on your calculator if you need an actual decimal.
12/÷(5/6) = 12×6/5 = 72/5=14.4
Answer:

Step-by-step explanation:
In every rectangle, when you have two diagonal segment bisectors, you will always have a circumcentre showing all midpoints of both segment bisectors, however, it measures 120° going <em>vertical</em> and 60° going <em>horisontal</em>, so with that being said, you have your answers.
