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.

The function D =25+0.3 X represents the daily dental charge D in dollars for X miles driven
Lady_Fox [76]

Answer:

See Explanation

Step-by-step explanation:

Given

D = 25 + 0.3X

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:

D = b + mx

Where

b = D\ intercept

m = slope

By comparing: D = 25 + 0.3X to D = b + mx

b = 25 and m = 0.3

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 D = 25 + 0.3X

D = 25 + 0.3 * 5

D = 25 + 1.5

D = 26.5

<em>The cost of 5 miles is $26</em>

Make use of the above explanation to solve the question

Use the functions f(x) = 2x + 7 and g(x) = 6x − 5 to complete the function operations listed below.
noname [10]

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 - 3
