The domain is the X values.
In an ordered pair, the X value is the first number.
The domain would be C. -2, 0, 4, 10
R = d/2.....the radius is half the diameter
Answer:
By calculating the time taken to reach we get to know that the The time taken by the other person is less than yourself
Step-by-step explanation:
Given that the other person and yourself left at the same time and the speed of the other person is 60 miles per hour and the speed of yourself is 40 miles per hour.
We know that the
Let the time taken to reach the destination at a distance of d by the other person is T1.
Then
Let the time taken to reach the destination at a distance of d by the yourself is T2.
Then
Now the time difference is = T2-T1 = =
Therefore T1 > T2 which means the time taken to reach the destination by yourself is greater than that of other person .

Answer:
2 1/2
Step-by-step explanation:
1200/480 = (240·5)/(240·2) = 5/2 = (4/2) +(1/2) = 2 1/2
Answer:
A. -1.25 ft/hour — the number of feet the pool depth changes in 1 hour
B. 1 is the depth in feet of the pool when x=0 (at the start of it being filled)
Step-by-step explanation:
In these questions, the pool depth is represented by a linear equation in slope-intercept form. The equation gives depth in feet while the independent variable represents a number of hours.
A slope-intercept equation has the form
y = mx +b . . . where m is the slope (rate of change) and y is the intercept
The y-intercept (b) is the "initial value," the value of y when x=0.

<h3>A. </h3>
The equation ...
y = -1.25x +5
represents the depth of water in the Kim family pool. Comparing to the slope-intercept form, we see m = -1.25. That is, the "rate of change" is -1.25. When that value is multiplied by x hours, it gives a result in feet. That is, the units of the rate of change are feet/hour.
The "rate of change" of -1.25 in this context is telling you the depth is decreasing by 1.25 feet every hour as the pool is being drained.

<h3>B.</h3>
The equation ...
y = 1/2x +1
represents the depth of water in the Gutierrez family pool. Comparing to the slope-intercept form, we see b = 1. This is the initial value of depth, the value when x=0, the pool has been filling for 0 hours. It means the water in the pool is 1 foot deep when the pool starts filling.
