Answer:
the rate of change is 20 calories per minute.
Step-by-step explanation:
5(v+2) = -2(7v-3) + 9
------------------------------------
Distribute:
5v + 10 = -14v + 6 + 9
Combine Like Terms
5v + 10 = (-14v+9v)+6
5v + 10 = -5v + 6
Subtract -5v from both sides
10v + 10 = 6
Subtract 10 from both sides
10v = -4
Reduce
5v = -2
Divide both sides by 5
v = -2/5
Simplify
v = -0.2
Answer:
x = 8
Step-by-step explanation:
Given
7 + (- 5x) = - 33
Note that + (- ) = -
7 - 5x = - 33 ( subtract 7 from both sides )
- 5x = - 40 ( divide both sides by - 5 )
x = 8
12miles
Step-by-step explanation:
