Answer:
a or b
Step-by-step explanation:
it should be p≥18
greater then or equal to 18. because if you have 18, you can get the group rate and I'd you have more than 18 you can also get the group rate.
For this graph the equation is x= -3
Because in the coordinates you gave, all the x values are -3 telling me that the line is a straight vertical line passing through the -3 x-axis and has no y-intercept as it's a vertical line, not diagonal, so it's not passing through the y-axis. Plus because of this too this line has no gradient.
I don't know if I am right but I think this is the answer:
If we write beaker with x and content with y
then y=56.8/2=28.4 this is the content of one beaker
so there are two beakers:
2x+28.4=180.4
2x=180.4-28.4
2x=152/2
x=76
X>2
y<-4
basically you find the answer when one intercept is equal to 0. Which is basically canceling it out
