Answer:
x=-2
Step-by-step explanation:
−5x−2+2x=−2x+4+2x
−3x−2=4
Step 2: Add 2 to both sides.
−3x−2+2=4+2
−3x=6
Step 3: Divide both sides by -3.
−3x
−3
=
6

Step-by-step explanation:
Given

The question has missing details; as what's required is not stated.
However, since it is a linear equation, possible questions could be
1. Determine the slope
2. Determine the D-intercept
3. Calculate the amount in dollars for (say) 5 miles
An equation is represented as:

Where


By comparing:
to 
and 
This means that the slope is 0.3 and the d intercept is 25
To get the amount for 5 miles, we substitute 5 for x in 



<em>The cost of 5 miles is $26</em>
Make use of the above explanation to solve the question
The answer is seven because if you divide 49 by 7 it equals 7.
We are given the two functions:
f(x) = 2x + 7
g(x) = 6x – 5
Part A. Find (f + g)(x)
(f + g)(x) = f(x) + g(x)
(f + g)(x) = 2 x + 7 + 6 x – 5
(f + g)(x) = 8 x + 2
Part B. Find (f ⋅ g)(x)
(f ⋅ g)(x) = f(x) ⋅ g(x)
(f ⋅ g)(x) = (2 x + 7) (6 x – 5)
(f ⋅ g)(x) = 12 x^2 – 10 x + 42 x – 35
(f ⋅ g)(x) = 12 x^2 + 32 x – 35
Part C. Find
f[g(x)]
f[g(x)] = 2 (6
x – 5) + 7
f[g(x)] = 12 x
– 10 + 7
f[g(x)] = 12 x
