It is like if you have two number lines. Then one has a pointer at 0, and the other one has the pointer facing at 2 then it will be lesser because the first one has 0 or if it turned around it would be greater. If it is equal then it would have the same number, but watch out if it is a negative number.
Answer:

Step-by-step explanation:
We have been given that a bean plant grows at a constant rate for a month. after 10 days, the plant is 30 centimeters tall. after 20 days, the plant is 50 centimeters tall.
First of all we will find slope of our line using given points.

Upon substituting coordinates of our given points in slope formula we will get,


Therefore, slope of our given line is 2.
Since the equation of a line in point slope form is
.
Upon substituting m=2 and coordinates of one point in above equation we will get,

Therefore, the equation that models the height of the plant (y) after x days will be
.
5% if you set up a proportion, it helps you out more.
Answer:
5 months is the answer. 21% of 2000 is 420 and 420x5=2100 which added up is $4,100 dollars and that is just over double the original amount.
Answer:
The solution is the point (-2,-2)
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by substitution
substitute equation A in equation B

Solve for x

Find the value of y
substitute the value of x in the equation A

so

therefore
The solution is the point (-2,-2)
