First we need to isolate the variable so we add 15 to both sides which is
w/4=43 then we need to multiply by 4 to both sides so its 4w=172
then divide by 4 which is 43 so the answer is w=43
The measure of a center and
variation are appropriate for the data is the mean or average. In this, you are
to add the data collected by Kinesha and then divide it by the number of data
obtained by Kinesha. The measure of center and variation is the mean scores.
Answer:
y = 1/3x - 8
Step-by-step explanation:
First you solve:
3x + y = - 5
Then subtract x since we're looking for y on both sides of the ( = ):
3x + y = - 5
-3x -3x
Making it:
y = -3x - 5
and then you make the slope ( m ) positive , like so :
1/3
then set up the equation :
y - y1 = m ( x - x1 )
and fill in the points they gave you :
( 3, -7 )
^x1 ^y1
Like this :
y - y1 = m ( x - x1 )
y + 7 = 1/3 ( x - 3 )
y + 7 = 1/3x - 1
-7 -7
y = 1/3x - 8
( If you have the calculator for it , you could always put the equation in and check if it goes through the point )
