Answer:

The value of x = -6

Step-by-step explanation:

Step(i):-

Given that g(x) = 2 x + 4 and g (x ) = -8

⇒ Equating

2 x +4 = - 8

Subtracting '4' on both sides, we get

2 x + 4 - 4 = -8 -4

⇒ 2 x + 0 = -12

⇒ 2 x = -12

Step(ii):-

Dividing '2' on both sides, we get

x = -6

The value of x = -6

Reagan and Nathan are 40 miles apart on a bike trail when they start pedaling toward each other on their b bicycles. Reagan ride

irinina [24]

Answer:

They meet in 2.22 hours.

Step-by-step explanation:

We can find the time at which Reagan and Nathan meet by equaling the time as follows:

$v_{R} = \frac{x_{R}}{t}$

$x_{R} = v_{R}t$ (1)

$v_{N} = \frac{x_{N}}{t}$

$x_{N} = v_{N}t$ (2)

Where R is for Reagan and N for Nathan.

Knowing that:

$x_{R} + x_{N} = 40 mi$

By adding equations (1) and (2) we have:

$x_{R} + x_{N} = v_{R}t + v_{N}t$

$t = \frac{x_{R} + x_{N}}{|v_{R}| + |v_{N}|} = \frac{40 mi}{8 mi/h + 10 mi/h} = 2.22 h$

Therefore, they meet in 2.22 hours.

I hope it helps you!
