Answer:
4/3 kg
Step-by-step explanation:
Let x represent a half brick, let y represent a 1 brick.
We know that 1 brick and 1/2 brick weigh 1 kg. so we represent this as
We know that obviously x is half of y. so
Subsitur this for x.
This means one block weight 2/3 kg. So how much 2 weigh.
For this we need to take value of f(x) when x = -3 and value of f(x) when x = 2, sum them up and divide by distance between x = -3 and x = 2
f(-3) = -36
f(2) = 4
average rate of change is:
Avg = (36 + 4)/(3+2) = 8
Note that we have to use +36 and not -36 because we need distance from -36 and 4 and that is 36 + 4 = 40... same goes for -3
153.5
Supplementary means add to 180
180- 26.5= 153.5
Answer:
-.5
Step-by-step explanation:
The point is halfway between 0 and -1 so therefor it must be -.5.
Hopefully that helps you <3
