Answer:
x<3 means x is less than 3.
Think about a number line, the more left you go, the smaller the numbers get.
So, to represent x<3, you would shade to the left.
Let me know if this helps!
Answer:
1/7
Step-by-step explanation:
The reciprocal is 1 over the number
The reciprocal of 7 is 1/7
-x+y-3z+4w=6^"dfv
+xd-y+23z=0
so x=1 and y=3
Answer:
Slope of equation x = 3 is not defined.
Step-by-step explanation:
The graph for equation
is attached.
As clear from the graph, x=3, is a straight line parallel to y-axis.
Slope:
- Since the given equation of line is parallel to the y-axis and parallel lines have same slope.
- Parallel lines have the same slope and will never intersect. Parallel lines continue, literally, forever without touching
Thus, the given equation will have the same slope as the y-axis.
The slope of y-axis is not defined.
Hence, the slope of this line is not defined.
Answer:
(-∞, -4] ∪ [5, ∞)
Step-by-step explanation:
Hi!
Alright, so greater (or less) than or equal to is denoted with a bracket.
If x is less than or equal to -4, then the bracket is on the left side.
(___, -4]
Because x is <em>any</em> number under or equal to -4, x can range from negative infinity. However, we use a parentheses for infinity because infinity can never truly be reached.
So, x
-4 = (-∞, -4]
X
5
Equal to = bracket
X is any number above 5, so
[5, ∞)
Because we want both of these, we use the union sign (∪)
so,
= (-∞, -4] ∪ [5, ∞)
