4(x+2)=4x+8

2(x-1)=2x-2

2(x+1)=2x+2

You use disruptive property when solving equations like this.

**Answer:**

- C = 0.97m
- $1164 for 1200 miles
- 845 miles for $820

**Step-by-step explanation:**

Given a car's **cost of operation is $485 for 500 miles**, you want an **equation** relating **cost for m miles**, and solutions to that equation for **1200 miles**, and for a **cost of $820**.

<h3>Cost per mile</h3>

The cost per mile is found by dividing the cost by the associated number of miles:

$485/(500 mi) = $0.97 /mi

<h3>Equation</h3>

The equation for the cost will show the cost as the cost per mile multiplied by the number of miles:

** C = 0.97m** . . . . . where C is cost in dollars for m miles driven

<h3>1200 miles</h3>

The cost for driving $1200 miles will be ...

C = 0.97(1200) = $1164

**The cost of driving 1200 miles is $1164**.

<h3>$820</h3>

The number of miles that can be driven for a cost of $820 is ...

820 = 0.97m

m = 820/0.97 = 845.36

**About 845 miles are driven for a cost of $820**.

D. asymptote

In the attached graph, the function has two asymptotes, one horizontal (the x-axis) and one vertical (the line x = 2).

A square has 4 sides of equal legnths

in your point of view, it looks tilted because it is actually a rhombus, a paralellogram (4 sided figure with 2 pairs of paralell sides) with 4 equal sides

to find the area, just multiply base by height (look at ilustration/attachmtns)

Ratios don't have to be "per" something, while rates are "per" something.

Ratios compare 2 or more values, as well as rates.
