Answer:
A=(16 -5 0 -9)-(3 -4 -11 24)
Step-by-step explanation:
The solution process for any algebraic expression is to "undo" what is done to the variable. Here, matrix A has (3 -4 -11 24) added to it. The next step is to undo that addition, by subtracting that amount from both sides of the equation. The result is ...
A = (16 -5 0 -9)-(3 -4 -11 24)

Answer:
C
HOWEVER: "Less Than" is usually depicted as a dashed line at the border. and there MUST be an OR between these two equations to include all of the blue area. An "and" there would exclude the area between the edge lines.
Step-by-step explanation:
2x + y < 10
y < -2x + 10
3x + 2y < 12
2y < -3x + 12
y < -1.5x + 6

Answer:
The triangle is obtuse, and isosceles.
Step-by-step explanation:
The triangle is obtuse because there is an angle above 90 degrees, which is 104 degrees. The triangle is also isosceles due to the two lines in the triangle which indicate that the size of each side are equal to each other. For a triangle to be isosceles, there have to be at least two sides equal to each other, and in this case the triangle has those two equal sides.
