|3x|=9, solve absolute value equation

Mashutka [201]

|3x|=9

3x=9 -3x=9
X=9/3 x=9/-3
x=3 x=-3

Whenever you have an absolute value sign you have to find both the positive and the negative because they didnt signs into the equation but sometimes a question will ask for strictly the positive value or the negative value but if its not stated, find both.

What is the equation of the line with a y-intercept of 4 and a point (8,8)

vladimir2022 [97]

Answer:

y=1/2x+4

Step-by-step explanation:

to find the slope you need to know the change in y over the change in x

(0,4) and (8,8)

8-4/8-0

Compare the two functions to see which has a greater rate of change. Function 1

AleksAgata [21]

Function 2 has greater rate of change

Step-by-step explanation:

In order to find the rate of change we have to covert the given linear functions in slope-intercept form

<u>Function 1:</u>

<u></u> $-2x+5y = 10$ <u></u>

Adding 2x on both sides

<u></u> $-2x+5y+2x = 2x+10\\5y = 2x+10$ <u></u>

Dividing both sides by 5

<u></u> $\frac{5y}{5} = \frac{2x+10}{5}\\y = \frac{2}{5}x +\frac{10}{5}\\y = \frac{2}{5}x+2$ <u></u>

Let m1 be rate of change of function 1:

<u></u> $m_1 = \frac{2}{5}$ <u></u>

<u></u>

<u>Function 2:</u>

<u></u> $-6x+3y = 18$ <u></u>

Adding 6x on both sides

<u></u> $-6x+3y+6x = 6x+18\\3y = 6x+18$ <u></u>

Dividing both sides by 3

<u></u> $\frac{3y}{3} = \frac{6x+18}{3}\\y = \frac{6x}{3} + \frac{18}{3}\\y= 2x+6$ <u></u>

Let m2 be the slope of function 2

<u></u> $m_2 = 2$ <u></u>

As we can see that

<u></u> $m_2>m_1$ <u></u>

Function 2 has greater rate of change
