<em>2 x - 5 = 4 x - 1 
combine variables and constants we get
2 x - 4 x = -1 + 5
- 2 x = 4 
dividing - 2 on other side
x = 4 / - 2

How to do the fractions
GaryK [48]
First you make the mixed numbers/fractions into improper fractions. After that, you must find the common denominator, the LCM of 9 and 6 (for the 2nd problem). After that, if you can, simplify the fraction to lowest terms, which also includes making it a mixed number/fraction.

I hope this helps! :)

a boat salesperson earns a 2.5% commission on the sale of each boat Find the commision earned on a boat that sells for 18,500
marin [14]
100% = 1.0
2.5% = 0.025

So now we know the decimal that corresponds to 2.5%, so all we have to do is multiply the price of the boat by this value in order to find the commission earned:

18 500 x 0.025 = $462.50

Given f(x) = 2x2 - 4, find the average rate of change from x1 = -2 to x2 = 4.
Oduvanchick [21]

Answer:

The average rate of change = 4

Step-by-step explanation:

Given the function

f\left(x\right)\:=\:2x^2\:-\:4

x₁=-2, x₂=4

f(x₁) = f(-2) = 2x²-4 = 2(-2)²-4 = 8-4 = 4

f(x₂) = f(4) = 2x²-4 = 2(4)²-4 = 32-4 = 28

The average rate of change = f(x₂) - f(x₁) / x₂ - x₁

                                                = (28-4)/(4-(-2))

                                                = 24/6

                                                = 4

Thus, the average rate of change = 4
