It is -2/3
I gotchu don’t worry !
if they had spend 1500 total for goods and expenses 500 which is total 2000 and
revenue is 3000
1500 + 500 - 3000 = 1000 is profit for the business
Average rate of change is just the slope betwen the points
that is just the slope between (-3,-3) and (-4,-1)
slpe between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
so slope between (-3,-3) and (-4,-1) is (-1-(-3))/(-4-(-3))=(-1+3)/(-4+3)=2/-1=-2
the average rate of change is -2
First you should add all the sides of the pillows then multiply it by 3.
Answer:
1. x + 24 = 3x
24 = 3x - x
24 = 2x
12 = x
3x
3 (12)
36
2. 10x - 27 = 7x
10x - 7x = 27
3x = 27
x = 9
7x
7 (9)
63
3. 5x + 1 = 6x - 13
5x - 6x = -13 - 1
-x = -14
x = 14
5x + 1
5 (14) + 1
71
4. 6x + 3 = 4x + 39
6x - 4x = 39 - 3
2x = 36
x = 18
6x + 3
6 (18) + 3
111
