When a person is breathing normally the amount of air in their lawns varies sinusoidally. When full Karen's lungs hold 2.8 L of air when empty her Lawrence hold 0.6 L of air her brother starts timing her breathing at T equals two seconds she has exhaled completely and at T equals five seconds she has completely inhaled. Create an equation for this

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

noncoplanar points are points that do not lie on the same line.

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
