X + y = 12 x - y = 10, the value of the x-determinant for the system shown is -2. Solution: determinant = (1*-1) - (1*1) = -2.
Answer:
a large dance star
Explanation:
because it is bigger and heavier
The distance between the campsite and the rest area is 9 miles.
The given parameters:
- <em>Initial speed of the campers, u = 4.5 mph</em>
- <em>Final speed of the campers, v = 4 mph</em>
<em />
Let the time of motion from the campsite to rest area = t (hours)
Time for return trip = t hours + 15 mins
= (t + 0.25) hours
Let the distance between the campsite and rest area = d
d = 4.5t
d = 4(t + 0.25)
4.5t = 4(t + 0.25)
4.5t = 4t + 1
4.5t - 4t = 1
0.5t = 1
t = 2 hours
The distance between the campsite and the rest area is calculated as follows;
d = 4.5t
d = 4.5 x 2
d = 9 miles
Thus, the distance between the campsite and the rest area is 9 miles.

The matchup statement associated with rods or cones are:
<h3>Rods:</h3>
- involved with night vision
- smooth plasma membrane surrounding the intramembranous discs
- uses rhodopsin
- used in scotopic vision
- absorption peak occurs at 500 nm
<h3>Cones:</h3>
- highly concentrated in and around the macula
- involved with color vision
- infolded plasma membrane surrounds each disc
- uses photopsin
- absorption peaks occur at 420, 531, and 558 nm
<h3>What are the roles of rods and cones in the eye?</h3>
The Rods are known to help in regards to vision at low light levels or scotopic vision.
The cones are known to help or function in regards to vision at the point of higher light levels or what we call photopic vision.
Hence the matchup above are correct.
