|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.
Answer:
it dropped 48 degrees Celsius (c) in 8 hours
Step-by-step explanation:
6x8=48
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
slope is 1/2
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>
<u></u>
Adding 2x on both sides
<u></u>
<u></u>
Dividing both sides by 5
<u></u>
<u></u>
Let m1 be rate of change of function 1:
<u></u>
<u></u>
<u></u>
<u>Function 2:</u>
<u></u>
<u></u>
Adding 6x on both sides
<u></u>
<u></u>
Dividing both sides by 3
<u></u>
<u></u>
Let m2 be the slope of function 2
<u></u>
<u></u>
As we can see that
<u></u>
<u></u>
Function 2 has greater rate of change
