Answer:
The answer A. "The absolute value of a number gives its distance from zero on the number line."
Step-by-step explanation:
An absolute number has these in it '| |'. An absolute number always is positive, because it represents a difference.
For example, the difference of 0 and -30 is |30|.
Though 0 - 30 is -30, the DIFFERENCE is |30|.
As the answer says, "its distance from zero on the number line".
Answer:
<u>Option d</u>
Step-by-step explanation:
The graph of an inverse relation is the reflection of the original graph over the identity line, y = x.
So, the graph which contain the line y = x is the correct graph
Graph a ⇒ includes a function, its inverse, and the line x = 1
Graph b ⇒ includes a function, its inverse, and the line y = -x
Graph c ⇒ includes a function, its inverse, and the line y = 1
Graph d ⇒ includes a function, its inverse, and the line y = x
<u>So, the answer is option d</u>
The value of y when x = 5 is 45
<h3><u>Solution:</u></h3>
Given that y varies directly with x. This can be written mathematically as:
y ∝ x
---- eqn 1
Where "k" is the constant of propotionality
Given y = 27 when x = 3. Substitute these values in eqn 1
<h3>k = 9</h3>
Substitute k = 9 in eqn 1
y = 9x ----- eqn 2
<u><em>To find: y = ? and x = 5</em></u>
Substitute x = 5 in eqn 2
Thus the value of y when x = 5 is 45
