Answer:
i think its A
Step-by-step explanation:
divide both sides by -2 which makes the y int -3 and A has a negative slope
Answer:
- Population: Soil around a former waste dump
- Parameter: Concentrations of toxic chemicals
- Sample frame: Accessible soil around dump
- Sample: 16 soil samples
- Method: Unclear
- Bias: Uncertain if soil samples were randomly chosen
Step-by-step explanation:
The above answer explanation can be more clear by understanding that the population is the soil around the former waste dump and the samples are 16 which were taken from EPA.In report, the method is unclear too.
8-4x-7=5x+30-2
combine like terms
1-4x=5x+28
-27=9x
divide both sides by nine
-3=x
All the choices are in the slope-intercept form where,
y=mx+b
so, the number before the x is the slope. The given slope is -34. We just have to look for the -34 number before the x. So mong the choices, it is the letter a choice that has the slope -34. So the answer is A.
