There are two sets of Y values identical ( 0 and 5 ).
There are two sets of identical X values ( -1 and 2)
This makes a rectangle.
The length is 5-0 = 5
The width is 2 - -1 = 3
Area = Length x width = 5 x 3 = 15 square units.
Answer:
y=5x
Step-by-step explanation:
Because if you look at it 5x any of them would equal the answer
Since there isn't a line under the < sign, this means that we used a dotted or dashed line. The dotted or dashed line indicates that we do NOT include the boundary as part of the solution set.
Since y is isolated and we have a less than sign, this means we shade below the dashed/dotted boundary line. Specifically, the boundary line is the graph of y = 2x+1. This boundary line goes through (0,1) and (1,3). Again, points on this boundary line are NOT part of the solution set.
So in summary we have:
A dashed or dotted boundary line
The shaded region is below the dashed/dotted boundary line.
Answer:
The left side of the equation is ignored
i is treated as -1, which it is not, it is instead the square root of negative 1.
To solve it properly we get:
(2 - 5i)(5 + 2i)
= 10 + 4i - 25i - 10i²
= 10 + 21i + 10
= 20 - 21i
