Mathematics

Proportional is
if you have
y=number of pits
x=profit

then
y1/x1=y2/x2
y1 and x1 are first number of pits and profit
y2 and x2 and second number of pits and profit

so

given
3 pits and 80 then
5 pits and 200
12 pits and 620
3/80=5/200=12/620
true?
3/80=1/40=3/155
use caltulator
0.0375=0.025=0.019
these are obiously not equal
so the answer is no, so either c or d

hmm
c means that the slope (or the values we calculated) wer less than original
0.0375>0.025>0.019
true

d. this is also true since they are not proportional


not sure, it is either c or d, I would go with d

What happens to the value of the expression 70 - 3g as g increases
exis [7]

Answer:

It decreases

Step-by-step explanation:

Given the expression: 70-3g

  • When g=1, 70-3g=70-3(1)=70-3=67
  • When g=2, 70-3g=70-3(2)=70-6=64
  • When g=3, 70-3g=70-3(3)=70-9=61
  • When g=4, 70-3g=70-3(4)=70-12=58
  • When g=5, 70-3g=70-3(5)=70-3=55

From the above, notice that as g increases, the value of the expression decreases.
