Answer:
The solution set is {-7, 7}.
Step-by-step explanation:
He was half right .There are 2 solution d = -7 and d = 7.
Well, since a is Susan’s current age, we would add three to a to get her age in three years
So our expression would be:
a + 3
The solutions are given by the intersections of the graphs, we conclude that the negative solution for x is x = -2.
<h3>Which point represents a negative solution for x?</h3>
Here we have a system of equations graphed, each graph (red and blue ones) represents each side of the given equation:
The red one represents the right side, while the blue one represents the left side.
Then, the solutions are all of these points where the two graphs intersect (meaning that both equations have the same value in that point).
Then, the negative solution for x is given by the intersection in the left side of the vertical axis, which happens at x = -2, so we conclude that the negative solution for x is x = -2
