If x + 3(2x-5) = 6 then x =<br> O<br> -3<br> 3<br> O 15<br> O Option 4<br> O-14
Ronch [10]
<h2>x = 3</h2>

Step-by-step explanation:

x + 3(2x - 5) = 6 \\ x + 6x - 15 = 6 \\ 7x = 6 + 15 \\ 7x = 21

\frac{7x}{7}  =  \frac{21}{7}  \\ x = 3

Step 1 Use 3 to open the bracket

Step 2: Collect like terms and simplify

Step 3: Divide both sides by 7

Answer:

A. y = 80x

B. g(x) = 80x

C. To graph the equation, plot a point at (0,0) and a point at (1,80). Connect the points. Continue adding points by moving up $80 and over 1 day.

Step-by-step explanation:

Part A:  

To write an equation, use y= mx where m is the slope, x is the number of days, and y is the rent cost.

x and y remain the same in the equation.

To find m, use the slope formula with (5,465) and (7, 625).

m=\frac{y_2-y_1}{x_2-x_1}= \frac{625-465}{7-5} =\frac{160}{2} =80

It costs $80 a day.

The equation is y = 80x.

Part B:  

Function notation replaces Y as g(x). So the equation is g(x) = 80x.

Part C:

To graph the equation, plot a point at (0,0) and a point at (1,80). Connect the points. Continue adding points by moving up $80 and over 1 day.

vlada-n [284]
The absolute error is 4 cubic inches. To find the absolute error, you simply subtract the two values.

The percent error is 10%. To find the percent error, we create a fraction out of the error and the actual value.
4 / 40 x 100 = 10%
