They will make the same amount after 10 phones sold. Before that Plan A is the better plan. After 10, Plan B is the better plan.
You can find the point of intersection by modelling the two equations and setting them equal to each other. If x is equal to phones sold:
250 + 25x = 50x
250 = 25x
10 = x
Therefore, you make the same at 10 phones.
Answer: y = 2x - 11
Step-by-step explanation:
A linear equation has the following form.
y = a . x + b
where,
y: independent variable
a: slope
x: independent variable
b: y-intercept
The slope is 2, so a is 2. The ordered pair (4, -3) means that when x takes the value 4, y takes the value -3. We can replace these values in the general equation to find the y-intercept.
y = a . x + b
-3 = 2 . 4 + b
b = -11
The linear equation is
y = 2x - 11
Answer:
11
Step-by-step explanation:
4+5+7+14+17+12+18=77
Divide your total by the amount of numbers you have (7); 77/7
In standard form it would be 2x - 3y = 3
They can conclude that the certain animal ( of the fossil) had either migrated to that place or was brought to that certain place this is also proof of of the Continental Drift Theory that there was a Pangaea and split apart around a certain time.
