Answer:
Step-by-step explanation:
To write a linear inequalities we use the same guidelines as linear equations. They are written in the form, and or with any other inequality signs.
One line has y-intercept 2 and slope is -5/1 (down 5 and over 1).
This means the equation is
.
Test a point not on the line to determine the direction of the inequality sign.
(0,0)
This is true but not the equation becasue (0,0) is not shaded.
The other line has y-intercept -4 and slope 3/1 (up 3 and over 1).
This means the equation is
.
Test a point not on the line to determine the direction of the inequality sign.
(0,0)
This is false and the equation since (0,0) is not in the shaded portion.
Answer: The third one! Move all terms not containing a from the center section of the inequality 1 < a < 8
How much money is that?? In America
Answer:
D
Step-by-step explanation:
Two matrices are equal when they
- have the same sizes (so options A and B are false)
- have equal corresponding elements (so option C is false, because -6≠6, -6.5≠6.5, 1.7≠-1.7 and so on)
If in option D the second row is 2 -8.5 19.3 , then these matrix is equal to the given.
The answer would be -8 ≤ x ≤ 2
