5x-17 = 48

5x = 48-17

5x = 31

x = 31/5

x = 6.2

y = 180 - [5(6.2)-17 ]

y=166

**Answer:You answered 19 questions correctly and 1 question wrong**

**Step-by-step explanation:First you have to divide 20 by whatever number that can get you to the number 100 by 20,which is 5(100 divided by 5 equals 20)Lastly you have to divide 95 by 5 and you get 19!**

**Answer:**

**Step-by-step explanation:**

<u>Given equation:</u>

<u>Change to slope-intercept form:</u>

- 2x + 3y = 1470, isolate y
- 3y = -2x + 1470, divide all terms by 3
- y = -2/3x + 490

The slope is **-2/3** and y-intercept is **490**

<u>Functional notation, change y to f(x)</u>

To graph the line, plot the intercepts and connect with the line.

<u>If the total is $1593 for the next month, the function would be:</u>

<u>Changing to slope-intercept:</u>

The slopes are same, therefore the lines are parallel.

The difference is the y-intercept, it is greater in the next month.

The graphs are attached, with intercepts shown.

A circle has 360 degrees

so circumference = (360 / 60) * 3 = 6*3 = 18 feet
