I’m not entirely certain, but here’s my attempt: d=2.5t+2.2 closely resembles y=mx+b with y=d, m=2.5, x=t, and b=2.2. To derive a new equation, we replace d and t, resulting in 1=2.5(0)+b. After simplification, we find b=1, so the new equation becomes d=2.5t+1

Answer: The unknown values x and y correspond to 8 and 20, specifically;
(x, y) = (8, 20)
Step-by-step explanation: The equation y = 16 + 0.5x represents a linear relationship that can be illustrated with a graph. This indicates that values for x and y can be located at various points on the line.
The ordered pairs signify that for each x value, there exists a matching y value.
The values listed in a two-column format for x and y all fulfill the equation y = 16 + 0.5x. Observing the first example, the pair (-4, 14) is presented.
This reveals that when x is -4, y will be 14.
Where y = 16 + 0.5x
y = 16 + 0.5(-4)
y = 16 - 2
y = 14
Thus, the first pair, similar to the other pairs, satisfies the equation.
Consequently, by reviewing the options provided, we can deduce which one fulfills the equation.
(option 1) If x = 0
y = 16 + 0.5(0)
y = 16 + 0
y = 16
(0, 16)
(option 2) If x = 5
y = 16 + 0.5(5)
y = 16 + 2.5
y = 18.5
(5, 18.5)
(option 3) If x = 8
y = 16 + 0.5(8)
y = 16 + 4
y = 20
(8, 20)
Our calculations confirm that the third option (8, 20) is the correct ordered pair for x and y.
The calculated 95% confidence interval for the percentage of coffee drinkers expressing addiction ranges from 21% to 31%. By defining the sample proportion and acknowledging a sample size of 675, while also factoring in a maximum margin of sampling error set at ±5%, the final confidence interval for addiction rates among all surveyed coffee drinkers is established.
Subtracting seven from sixteen results in nine
The solution is nine
The flea experiences an acceleration of 1,000 m/s².
Detailed explanation
This scenario involves motion with constant acceleration.
The relevant variables include the following.
We know the flea attains a takeoff velocity of 1.0 m/s over a distance of 0.50 mm.
The flea starts from rest, so the initial velocity is zero. The question asks for the flea's acceleration during leg extension.
The equation we apply is:
- a = acceleration (m/s²)
- u = initial speed = 0 m/s
- v = takeoff velocity = 1.0 m/s
- d = displacement = 0.50 mm
First, convert 0.50 mm to meters: 
Solution steps:
Rearrange the formula to isolate acceleration (a).
Insert the given values into the rearranged equation.
This yields the flea's acceleration as 1,000 m/s².
