Since x is less than 0 we have to use -2x.
Substitute -3 for x.
f(x) = -2(-3)
f(x) = 6

Hi there! Think of x as 2 and 6 and think of y as 8 and 12. 8-12/2-6=-4/-4. Now, -4/-4=1. Therefore, the answer is C. 1
Answer:
There is approximately 5.475 liters of blood in the body.
Step-by-step explanation:
At a resting pulse rate of 75 beats per minute, the human heart typically pumps about 73 ml of blood per beat.
73 ml in liters = liters
Now, 75 beats/min x 0.073 liters/beat = 5.475 liters/min
And 5.475 liters/min x 1 min/body = 5.475 liters/body
Hence, there is approximately 5.475 liters of blood in the body.
For the top: 10(4-7), distribute the 10 to both 4 and -7
10(4) = 40
10(-7) = -70
For the bottom, - is the same as - 1
Distribute -1 to both 4 and -1
-1(4) = -4
-1(-1) = 1
(40 - 70)/(-4 + 1)
Simplify. combine the terms.
40 - 70 = -30
-4 + 1 = -3
Divide:
-30/-3 = 10
D. 10 is your answer
hope this helps
