Answer:Ramiro’s method is
Step-by-step explanation:
Did the assignment
Answer:
The answer is 45600 as 621 is less than 650 and should be rounded down.
Draw the graph for each side, member, of the equation and see where the curves cross, are equal. The x values of these points, are the solutions to the equation.
Consider inequality 
This inequality is equivalent to inequality 
This means that 
The greatest integer number n, such that 
when dividing by 7 gives the remainder 4 is 39. Then subtract 7, you get 32, then 25 and so on.
When n=-39, -32, -25, -18, -11, -4, 4, 11, 18, 25, 32, 39 then dividing by 7 the remainder is 4.
Answer: 12 integers.
Answer:
y=-4 is a function
Step-by-step explanation:
It passes the vertical line test, and each x has only one y, so it is a function.
x = -4 is NOT a function because one x has multiple y values. It does not pass the vertical line test.
