Answer:
By delivering oxygen to the cells
Step-by-step explanation:
This is the answer because:
The respiratory system is responsible for moving gases into and out of the blood because it gives the bloodstream the oxygen needs. The circulatory system is responsible for moving blood to all parts of the body and transport nutrients. The circulatory system works with the respiratory system to exchange carbon dioxide and oxygen.
6.
Intersecting chords:
RT x ST = PT x TQ
2 x 6 = 3 x TQ
12 = 3TQ
TQ = 12/3
TQ = 4
7.
AD = 90 -BE = 90-18 = 72
ADE = 180. DE = 180 - AD = 180-72 = 108
AE = 180. AB = 180-18 = 162
DE = 108
BD = BE +DE = 18 + 108 = 126
DAB = 72 + 162 = 234
ADE = 90 degrees
8.
AB^2 = BC* (BC +x)
8^2 = 2 * (2 +x)
64 = 4 + 2x
60 = 2x
X = 60/2
X = 30
Answer:
(-2, 4)
Step-by-step explanation:
The solution to the systems of equations shown on the graph is the point at which the lines of both equations intersect each other.
The solution is (-2, 4). That is, for both lines, when x = -2, y = 4.
