Answer:
x=8
Step-by-step explanation:
-4 = 12 - 2x
when plus 12 goes to the left hand side it changes its sign so,
-4 -12 = -2x
- * - is plus so add 4 and 12 but keep the sign - because 12 is the greatest number and its sign is -
-16=-2x
when -2 comes to the left hand side it changes its from multiplication to division.So,
-16/-2=x
8=x
we will get positive 8 because minus and minus also gets cancel.
For this case we have the following equation:
v = v0 + at
Where, we have the following values:
v0 = 20 meters / second
a = 1.5 meters / second2
t = 4 seconds
Substituting values we have:
v = 20 + (1.5) * 4
v = 26 meters / second
Answer:
The car's final velocity is:
v = 26 meters / second
Answer:
A(t)=-1.5t-7
Step-by-step explanation:
It is given that Mr. Mole left his burrow that lies 7 meters below the ground and after 6 minutes, he was 16 meters below the ground.
It means the line passing thought the points (0,-7) and (6,-16). It means the initial value is -7.
He started digging his way deeper into the ground, descending at a constant rate. The rate of change is
The rate of change is -1.5.
A(t) denote Mr. Mole's altitude relative to the ground A (measured in meters) as a function of time t (measured in minutes).
Therefore the function's formula is , here negative sign shows the Mr. Mole's altitude relative to below the ground A
