The correct answer is A. $18
8 x 125% or 8 x 1.25 = 10
Add $10 to $8 and you get $18
R=16
J=32
20+40(which is 20×2)=60
20-4=16
16×2=32
The correct answer is option D.which is -4 ≤ x ≤ 1.
<h3>What is a graph?</h3>
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
in the graph, we can see that the value of x is increasing from -4 coordinate of x to the 1 coordinate of x so the interval will be given as -4 ≤ x ≤ 1.
Therefore the correct answer is option D.which is -4 ≤ x ≤ 1.
