Answer:
x=-1/2
Step-by-step explanation:
-3(x-4)= -9(x-1)
-3x+12= -9x+9
-3x+9x= 9-12
6x= -3
x=-3/6
x= -1/2

See both answers in the explanation
Step-by-step explanation:
Given data
Cost of dinner= $32
TIp=18%
Let us find the amount of the tip
=18/100*32
=0.18*32
=$5.76
Hence the total amount paid is
=5.76+32
=$37.76
The Tip is
=$5.76
The mean/average is found by adding all of your values and then dividing by the number of values found.
7+7+7+7+7+7+7+7+7+7=70
There are 10 size 7 shoes. Divide 70 by 10 to get the mean, which is 7.
Another ex.
Find the average of numbers listed
1+4+8
these add up to 13
there are 3 numbers listed
13/3=4.33 so the mean is 4.33

Step-by-step explanation:
Under a rotation about the origin of 180°
a point (x, y ) → (- x, - y ), thus
T(- 2, 5 ) → T'(2, - 5 )
