Answer:
Begin at the point, draw a vertical line either up or down to the x-axis to get the x-coordinate.
Begin at the point, draw a horizontal line either to the left or right of the y-axis to get the y-coordinate.
Step-by-step explanation:
In a two-dimensional plane, coordinates of a point define its exact location. The coordinate plane has two axes that are perpendicular to each other which are known as the x and y axis.
To find out the coordinates of a point in the coordinate system, follow the following procedure.
Begin at the point, draw a vertical line either up or down to the x-axis to get the x-coordinate.
Begin at the point, draw a horizontal line either to the left or right of the y-axis to get the y-coordinate.
The x-coordinate and the y-coordinate determine the new coordinates of a point.
The answer is:
[B]: -4 .
_____________________________Here is the problem:
_____________________ "Find f(3)."
_______________________ f(x) =
;
______________________________________
Since we are asked to find: " f(3)" ; we consider the number, "3", which is GREATER THAN OR EQUAL TO "-2" ; (that is, " 3
-2" ;
and f(x) = -4 if x
-2 .
_____________________________________________________So, in this case, f(x) = f(3) = -4 ; which is: "Answer choice: [B] ".

Answer:
This is the same as writing y = 650(0.907)^t
=====================================================
Explanation:
Exponential equations can be of the form y = a*b^t
- a = initial amount
- b = growth or decay factor
In this case, we have
- a = 650 mg to start with
- b = 1 - 0.093 = 0.907 as the decay factor
If we had exponential growth, then we'd compute 1 + 0.093 instead.
Based on those values, we go from y = a*b^t to y = 650(0.907)^t which is the same as writing
Other exponential forms are possible, but I think this form is the most intuitive. The 0.907 means that 90.7% of the sample remains after each year.
Y = 10x + 2. pls mark as brainliest
