Answer: -7/2
Step-by-step explanation:
Answer:
Step-by-step explanation:
As per definition of the function, every x- value (input) has exactly one corresponding y-value (output)
<u>We can see on the table:</u>
- x = 3.45 and y= 1.72
- x = 3.45 and y = 3.36
Two same input values with different outputs.
So this not a function
I am sending more pictures so you can see how I got the answer
Answer:
x=7
y=-1
Step-by-step explanation:
When the two equations are solved together, they form simultaneous equations.
x+y=6
x-y=8
Let us use the elimination method. if we add the two equations, we eliminate y.
2x=14
x=7
Let us substitute for the value of x obtained above.
x-y=8
7-y=8
y=7-8
y=-1
2/5 is the answer to your question
