Step-by-step explanation:
Here we will, Provide index power 5 on both the sides, so that we can cancel out the 5th power root in the L.H.S
so we get as,
==> x+7 = (-2)^5
==> x+7 = -32
==> x = -32-7
==> x = -39
hence, x = -39
Option A.) is correct.
Your answer would be ( -12/5 x + 2 )
Answer:
1st option.
0 to 100 miles per hour
Step-by-step explanation:
as we can see the question states that a particular car' s gas mileage DEPENDS upon its speed.
Since, the independent variable is the domain of the function the speed of the car will act as the domain of the given function.
out of all the option option 1 gives us values of speed( cause its unit is miles/ hour - unit of speed).
so the domain is
0 to 100 miles per hour.
6x + 52 > 130
Subtract 52 from both sides:
6x > 78
Divide both sides by 6:
X > 78/6
X > 13
The first one would be the government
