Answer:
x=-6
Step-by-step explanation:
5x-x-6=6(2x+7)
4x-6=<em>6(2x+7)</em>
4x-6=<em>12x+</em><em>42</em>
-8x=48 |:(-8)
x=-6
Given:
4 relations in the options.
To find:
The relation which represents a function.
Solution:
We know that, a relation is a function if there exist a unique output value for each input value.
In option A, we have two output values y=-5 and y=1 for single input value x=-1. So, it is not a function.
In option B, we have two output values y=2 and y=4 for single input value x=3. So, it is not a function.
In option C, we have two output values y=1 and y=7 for single input value x=-1. So, it is not a function.
In option D, we have unique output value for each input value. So, it is a function.
Therefore, the correct option is D.
Answer:
i think its A
Step-by-step explanation:
Are you needing help with the last box or what are u needing help with ?
C (1,8) and (4,5). To interpret a system of equations when shown a graph, look for the points at which the two function intersect or meet. in this case they meet at both points (1,8) and (4,5)
