Answer:
(32,16)
Step-by-step explanation:
When you dilate a coordinate by a factor say a, the coordinate of the image are multiplied by this factor to get the coordinate of the pre-image. For example, if the coordinate of the image is (x,y) dilated by a factor of "a", the coordinate of the pre-image will be (ax, ay)
Given the coordinate (16, 8) the coordinate of the pre image of dilated by a factor of 2 is given as;
(2×16, 2×8) = (32, 16)
Hence the coordinates for the pre-image Q is (32,16)
Which function represents exponential decay?
Answer:
the answer is c
Step-by-step explanation:
It appears that your thief is just as obsessive compulsive as you are. What is happening here is 'exponential decay' because the rate of decrease stays consistent from day-to-day. No matter how big your 'population' of jelly beans is on any given day, about 10% will vanish by the next day.
Solve absolute value inequality 4>|x+1|+2
Answer:
-3 < x <1
Step-by-step explanation:
4 > | x + 1 | + 2
1. Isolate the absolute value;
Inverse operations;
4 > | x + 1 | + 2
-2 -2
2 > | x + 1 |
2. Remove the absolute value;
The absolute value of a value is the distance it is from zero. This means that when removing the absolute value, one has to account for two possibilities; when the value within the absolute value brackets is negative, and when it is positive. In the case of dealing with absolute value inequalities, one will have to set up an inequality with this in mind.
2 > | x + 1 |
-2 < x + 1 < 2
Inverse operations
-2 < x + 1 < 2
-1 -1
-3 < x < 1
Answer:
-3<x<1
Step-by-step explanation:
